Poster

To perfectly showcase your poster background, we recommend the following procedure:

Preparation:
Thoroughly clean the outside back pane of your aquarium to ensure no dust or dirt interferes with the application.

Applying PosterFix:
Use a soft cloth to evenly apply a sufficiently thick layer of JUWEL PosterFix to the outer back side of the aquarium glass. A layer that is too thin could affect the result.

Attaching the poster:
Place the poster onto the damp surface and press it carefully into position.

Removing excess and air bubbles:
Use a plastic card or squeegee to remove any excess PosterFix and air bubbles by smoothing them outwards from the center.
To enhance the effect of your film background, use a cloth to apply a thin and even coating of JUWEL PosterFix to the outside of your aquarium’s back pane before attaching the background. Then press on the poster and use a piece of plastic card to scrape out any surplus PosterFix and any air bubbles that may have formed. PosterFix prevents unattractive light refraction, thus increasing the colours and structure of your motif to great effect.

HeliaLux APPControl

Recommendation: Restart your router, smartphone and controller beforehand - this is often the easiest way to resolve minor connection problems.

Please check the following:
Is your router up to date with the latest software version?
Is the MyJUWEL app up to date?
Is the DHCP server activated?
Has the router been switched to IPv4? (Alternatively, you can use dual-stack if your router supports this).
Are new devices authorised by the router firewall?
If your HeliaLux AppControl is not found when you add it to the MyJUWEL app, there may be several reasons for this:

Possible reasons:
a) Your HeliaLux AppControl is not in pairing mode. You can recognise the pairing mode by the fact that the blue LED flashes briefly, briefly, long.
b) The Bluetooth function of your smartphone is deactivated.
c) The HeliaLux AppControl is too far away from the smartphone.
d) The location service on your smartphone is not activated

How to solve the problem:
a) Reset the HeliaLux AppControl to factory settings.
To do this, press the Reboot button (E) once and then press and hold the Mode button (D) for about 10 seconds - until the red LED starts to flash. The device is now in pairing mode. Then restart the pairing process in the MyJUWEL app.
b) Activate Bluetooth in the connection settings of your smartphone. You can then start the pairing process again.
c) Make sure that your smartphone and the HeliaLux AppControl are within sight of each other so that the connection can be established reliably.
Possible reasons:
a) Either the wrong WLAN name (SSID) was selected during the set-up process or the WLAN password was not entered correctly.
b) The HeliaLux AppControl is outside the range of your Wi-Fi network.
c) The 2.4 GHz frequency range is deactivated in your router - however, this is absolutely necessary for the connection.

This is how you can solve the problem:
a) Reset the HeliaLux AppControl to the factory settings.
Press the Reboot button (E) once and then press and hold the Mode button (D) for 10 seconds until the red LED starts to flash. The controller now switches to pairing mode. Then restart the set-up process in the MyJUWEL app.
b) Ensure a sufficiently strong Wi-Fi signal at the location of your HeliaLux AppControl - ideally close to the router.
c) Check in the settings of your router whether the 2.4 GHz frequency range is activated. Without this, no connection to the device can be established.
If your HeliaLux AppControl has been successfully integrated and your smartphone is in the same WLAN, but the device status in the MyJUWEL app still shows ‘offline’, this may have the following reasons:

Possible causes:

The HeliaLux AppControl cannot connect to your WLAN or is outside the WLAN range. In this case, the blue LED flashes four times in quick succession (short, short, short, short).

You can resolve the problem as follows:

a) Perform a restart of your HeliaLux AppControl. To do this, press the Reboot button (E) on the device once.

b) Check your Internet connection and the router status. Make sure that your smartphone is connected to the same WLAN as the HeliaLux AppControl.

c) Ensure a sufficiently strong Wi-Fi signal at the location of your HeliaLux AppControl.

d) If the WLAN router has changed or you have changed the WLAN name (SSID) of your home network, please reset the HeliaLux AppControl to the factory settings: Press the Reboot button (E) once and then press and hold the Mode button (D) for approx. 10 seconds until the red LED flashes. The device is then in pairing mode. Then restart the pairing process in the MyJUWEL app.
To access your HeliaLux AppControl while travelling, it is important that both your smartphone and your home WLAN are connected to the Internet. If the device status is displayed as ‘offline’ even though the device has been successfully set up, this may be due to the following reasons:

Possible reasons:
a) Your smartphone currently has no Internet connection.
b) Your home network is not connected to the Internet.
c) The HeliaLux AppControl cannot connect to the WLAN or is out of range. In this case, the blue LED flashes four times in quick succession.
d) There has been a change to the router data, e.g. a new WLAN name (SSID) or a new router. In this case, the blue LED also flashes four times briefly.

You can resolve the problem as follows:
a) Check and activate the mobile data on your smartphone.
b) Make sure that your Wi-Fi router is connected to the Internet.
c) Check whether your WLAN is activated and ensure that the signal at the location of the HeliaLux AppControl is sufficiently strong.
d) If you have recently replaced the router or changed the WLAN name, reset the HeliaLux AppControl to the factory settings:
Press the Reboot button (E) once and then press and hold the Mode button (D) for about 10 seconds - until the red LED flashes. The device is now in pairing mode.
The firmware can be easily updated via the MyJUWEL app. To do this, open the MyJUWEL app, go to the settings and tap on the ‘Updates’ menu item.
All available updates for your connected devices will be displayed here. Tap on ‘Update now’ to start the firmware update.

Note: If the update process takes longer than five minutes, please close the MyJUWEL app completely and restart the update process.
With the HeliaLux AppControl and the HeliaLux SmartControl, we offer you two different options for conveniently controlling your HeliaLux Spectrum. Both solutions support the control of your aquarium lighting, but differ significantly in terms of operation and range of functions.

The HeliaLux AppControl was developed as a modern successor to the HeliaLux SmartControl and offers you extended functions and even more flexible control via the MyJUWEL app.

It completely replaces the HeliaLux SmartControl and will be the recommended solution for smart lighting control in future.

The HeliaLux AppControl gives you particularly flexible control via the free MyJUWEL app - conveniently via smartphone or tablet. A major advantage: you can already control various smart devices (e.g. your aquarium lighting or your automatic feeder) with the MyJUWEL app. You can also control your lighting very easily using voice commands via common voice assistants. Practical additional functions such as the synchronisation of several aquariums, the import and export of light profiles, a special service mode and a selection of pre-installed biotope profiles round off the range of functions. Impressive cloud effects can also be realised effortlessly.

The HeliaLux SmartControl offers you a solid solution for controlling your HeliaLux Spectrum via the browser. Control via app or voice assistant is not provided here.Worldwide access is also not possible - operation takes place locally via your home network. Nevertheless, the SmartControl offers you all the important basic functions such as cloud effects, import and export of light profiles, a service mode and predefined biotope profiles.
Yes, you need a smartphone to control your smart JUWEL aquarium lighting. Set-up and operation is carried out via our MyJUWEL app, which must be installed on your smartphone (Apple iOS or Google Android). The MyJUWEL app guides you step by step through the set-up process and allows you to control your lighting conveniently - simply and intuitively.

A WLAN network in the 2.4 GHz or 2.4/5 GHz range is also required to connect to the MyJUWEL app. A mobile WLAN hotspot is not sufficient.
Please make sure that both Bluetooth and the location service are activated on your smartphone.

Important: Even if the MyJUWEL app has access to the location, the service must also be activated in the smartphone settings. For a stable setup, we recommend placing the controller in the immediate vicinity of the router.
For the setup, we recommend deactivating the repeater for a short time or connecting the controller directly to the main router.
As soon as the setup is complete, the repeaters can be used again as usual.
The reset was not carried out. Service mode has been activated by mistake.
If the green LED on the controller regularly flashes briefly three times (briefly, briefly, briefly), the reset has not been carried out correctly and service mode (manual mode) has been activated by mistake. In this case, the controller is not in pairing mode - please carry out the reset again as described.
Note: First briefly press the Reboot button (button E) and then immediately press and hold the Mode button (button D) for at least 10 seconds - until the red LED starts to flash.

Important: Make sure that the change from the reboot button to the mode button is carried out quickly and without interruption. This is the only way to successfully reset the controller.

Checklist: Connecting your smart device to Wi-Fi (2.4 GHz, 802.11 b/g/n)

This checklist will help you successfully connect your smart device to your Wi-Fi network.
The device supports 2.4 GHz and the Wi-Fi protocols 802.11 b/g/n. Please go through the following
steps one by one.
- Use 2.4 GHz only: The device works exclusively on the 2.4 GHz band. Please disable 5 GHz during setup or create a separate 2.4 GHz network (e.g. “WLAN_24”).
- Enable Wi-Fi mode b/g/n: The device requires 802.11b mode. Please make sure your router is set to b/g/n mixed and not to “n-only”.
- Check the Wi-Fi channel: Many devices support only channels 1–11. Set the channel manually to 1, 6, or 11.
- Check the Wi-Fi password: The password must be between 8 and 63 characters long. Avoid special characters (ä, ö, ü, ß, €, spaces at the beginning or end) and use only letters and numbers.
- Wi-Fi name (SSID): Avoid special characters and emojis in the Wi-Fi name. The SSID must not be hidden.
- Router security: Enabled: WPA2-PSK (AES or TKIP/AES). Not enabled: WPA3-only, “PMF required”, MAC filtering, client isolation, or a guest network with isolation.
- Mesh / repeater: Connect the device directly to the main router. Disable repeaters or mesh nodes during setup.
- Enable DHCP: Make sure DHCP is enabled and that there are enough free IP addresses available.
- Smartphone settings: During setup, turn off mobile data and VPN, enable location services, and stay close to the router.
Note: The device transmits with +20 dBm output power in 802.11b mode. A stable
connection is only guaranteed if the router meets the conditions listed above.
Recommendation: Restart your router, smartphone and controller beforehand - this is often the easiest way to resolve minor connection problems.

Please check the following:
Is your router up to date with the latest software version?
Is the MyJUWEL app up to date?
Is the DHCP server activated?
Has the router been switched to IPv4? (Alternatively, you can use dual-stack if your router supports this).
Are new devices authorised by the router firewall?
How do the smart devices behave in the event of a power outage or internet outage?

The behavior of our smart devices depends on the type of outage:

a) Power outage – power and internet are available again afterwards

As soon as power is restored and the router has re-established an active internet connection, the devices automatically reconnect to the Wi-Fi.
The current time is synchronized correctly, and all saved programs continue to run as usual without any time shift.

b) Power outage – power is back, but no internet is available

If power is available but the router has no internet connection, the devices cannot retrieve the current time.
In this case, they start internally at 00:00 from the moment power is supplied. The programs will still run, but with a time offset because the correct time is missing.
As soon as the internet connection is restored, the devices automatically re-synchronize.

c) No power outage – only Wi-Fi or internet fails

If only the Wi-Fi or internet connection fails, the devices remain in operation.
Since the time is already known, the saved programs continue to run correctly and without interruption. An internet connection is not required for this.

Accessories

Every JUWEL aquarium is already equipped for easy installation of an automatic feeder by JUWEL. The EasyFeed can be programmed for two feeding cycles a day, and allows you to feed your fish at intervals of six hours. JUWEL Aquarium has developed the SmartFeed to allow for more comfortable feeding with a more comprehensive range of functions. This automatic feeder can be programmed for three feeding cycles a day with 8 different dosing levels. The integrated display facilitates programming and provides for an overview of your settings. Two conveyor screws for flake and granulate feed are included, so you can adjust your automatic feeder to your type of feeding. A feed chamber extension is also included, to allow for automatic feeding during even longer periods of absence.
Both models are ideal tools for cleaning your JUWEL inside filter and the ground material of your JUWEL aquarium. The AquaClean works by means of the Quickstart system, that transports the water flow and dirt into a bucket by means of a shaking motion and without any inconvenient suction. The AquaClean 2.0 has been revised, and the previously used Quickstart system has been replaced by the Easy Start System. Simple, repeated squeezing of the pump activates the water flow immediately.

General information on the connection

Our smart devices from JUWEL Aquarium deliberately use a 2.4 GHz Wi-Fi connection, as this offers a significantly greater range compared to 5 GHz. This ensures a stable connection, even if your aquarium is a little further away from the router.
Before setting up, please ensure that your router is either set to 2.4 GHz or working in automatic mode (2.4/5 GHz). This will ensure that your devices can be connected without any problems - for reliable control directly via the MyJUWEL app.
Note: If your router cannot establish a connection in automatic Wi-Fi mode, you must temporarily deactivate 5GHz in your router.

Please deactivate 5 GHz WLAN during setup.
You can then reactivate automatic mode on the router.
Recommendation: Restart your router, smartphone and controller beforehand - this is often the easiest way to resolve minor connection problems.

Please check the following:
Is your router up to date with the latest software version?
Is the MyJUWEL app up to date?
Is the DHCP server activated?
Has the router been switched to IPv4? (Alternatively, you can use dual-stack if your router supports this).
Are new devices authorised by the router firewall?
You can use any characters in your Wi-Fi password as long as it is no longer than 32 characters.

Attention: Please note that if the router password is changed after a successful connection has been established, the controller switches to connecting mode because it still recognises the old password. It will practically ‘wait’ until the old password is restored and cannot be reached in this mode. However, profiles will continue to be played back.

Note: If the WLAN password has changed, please set the AppControl to pairing mode and connect it again via the MyJUWEL app. The controller cannot be controlled until this is done.

Aquariums/Cabinet

A JUWEL aquarium can be operated extremely cost-efficiently. It is important to remember that the electricity consumption depends on various factors, such as the size of the aquarium, the power of the pump, the lighting and the water temperature.

To measure the electricity consumption of a typical JUWEL aquarium, we took into account 8 hours of lighting per day, an ambient temperature of 22°C and a water temperature of 24°C, as well as three summer months without heating.

Based on an electricity price of 40 cents per kilowatt hour, the average electricity consumption of a JUWEL aquarium is about 29 cents per day. The precise electricity costs will depend on the model of the aquarium, as shown in the table below:
No. Our aquariums are produced using robot-supported processes. This includes the automated application of silicone to the bottom pane. The bulge is merely a point where the applied silicone seams overlap, which is necessary for production. This does not affect the leak-tightness of your aquarium. You can use the aquarium without any reservations.
Our production is geared towards producing complete aquariums. Unfortunately we are not able to consider any special requests with regard to our equipment. This is not possible, due to the fact that our manufacturing process is only suitable for serial production.
The JUWEL aquarium features a safety base frame which ensures an even distribution of the weight. Please do not use a mat under any circumstances!
We guarantee all of our products for 2 years from the date of purchase. Filter sponges and fluorescent tubes as well as all components that are subject to normal wear, e.g. the impeller of the pump, are excluded from the guarantee. Any guarantee claim must be substantiated with a valid proof of purchase.
Arrange the aquarium in accordance with the instructions for use and assemble the filter. In this context, please make sure that the filter media are positioned correctly, e.g. as this is also shown on the packaging of the filter display box. Remove all plastic bags that might protect the filter media (carbon sponge, filter floss, Nitrax sponge and optional Cirax/Phorax basket). If you wish to glue a background or a filter cover into your aquarium, this is the best time. Then load the aquarium with the ground material and the plants as well as other decorative elements, e.g. stones and roots. After that, fill the aquarium with water. Tip: It is best to carefully pour the water through the filter in order to protect the existing set-up. Run the aquarium without fish for approx. 10 days in order to let the important bacteria form in the filter sponges and clear the water of pollutants. Use bioBoost to activate new filter media faster, and thus shorten the run-in period of your aquarium. Use the advice of your specialist retailer.
Unfortunately we are not able to make any general statements about an aquarium’s service life, as this depends on a wide range of different factors. However, we do have customers who have been using their aquariums for more than 20 years without any problems.
Thanks to specially developed float glass, JUWEL aquariums can bear a multiple of their filled weight. Please make sure, however, to observe your base cabinet’s load capacity. For details about the maximum load capacity, please see the technical data provided on our website.
On current models, you will find your aquarium’s model name on the support beam. The model can also be specified based on the aquarium’s shape and width. Our service team will be happy to help you with this.

MyJUWEL APP

Recommendation: Restart your router, smartphone and controller beforehand - this is often the easiest way to resolve minor connection problems.

Please check the following:
- Is your router up to date with the latest software version?
- Is the MyJUWEL app up to date?
- Is the DHCP server activated?
- Has the router been switched to IPv4? (Alternatively, you can use dual-stack if your router supports this).
- Are new devices authorised by the router firewall?
Yes, in order for the MyJUWEL app to find the controller correctly via Bluetooth and WLAN, it needs access to the location.
Please allow the MyJUWEL app all requested authorisations the first time you start it.
So that your WLAN devices can automatically connect to our MyJUWEL app, the release of so-called ‘location data’ is required. Don't worry: this is not GPS data - your location is not actually requested.
The background to this is that Wi-Fi devices communicate via the names of the available networks in your neighbourhood. According to legal requirements, this network information is already considered location data, as it could theoretically allow conclusions to be drawn about your position. The operating system must therefore display this information - even if no location tracking takes place in practice.

Important to know: This data is used exclusively for communication between your smartphone and the control unit. It is not forwarded to our servers. The sole purpose is to ensure that your devices can reliably find and connect with each other.

Filtering

The circulating pump of the JUWEL inside filter pulls the water from the upper and lower water layers of the aquarium into the filter. Due to the special construction of the filter, the water passes from the top to the bottom through the filter media which greatly simplifies the filter maintenance. The filter media are: The white poly pad as mechanical pre-filter. Tip: It absorbs the rough dirt and prevents the other filter media from clogging quickly. The replacement is realised in a simple, quick manner and ensures the full functionality of the system. The black carbon sponge binds chemical contaminations. The green Nitrax sponge contains special micro-organisms that break down nitrate and consequently counter the growth of algae. The blue coarse filter sponge represents the biological filter stage I. Separation of the water flow Part 1 of the filtered water is directly returned to the aquarium through the riser of the pump. Part 2 of the filtered water moves to the “second” filter stage of the biological “slow filter”. Cirax, the white basket with the filter ceramics, filters with a large surface under aerobic (= oxygen-enriched) conditions. The blue, fine-pored filter sponge represents biological filter stage I which operates in a strong manner under anaerobic (= oxygen-deficient) conditions. After that, the water that has been filtered repeatedly flows back into the aquarium.
The suction power can be adjusted using the flow regulation tube. By turning the regulation tube, the strength of the surface suction can be individually adjusted.
Yes. The JUWEL EccoSkim can be directly attached to the filter system in JUWEL aquariums of the Rio, Lido, Vision, Trigon and Primo 110 series.

For all aquariums
Thanks to the matching suction holder, the JUWEL EccoSkim is also suitable for use in aquariums from other manufacturers.
The JUWEL inside filter "Bioflow" is a biologically operating aquarium filter. The filters are adapted to the respective aquarium volume in an ideal manner: The capacity of the filter pump is designed for twice or 3 times the throughput per hour (e. g. Rio 180 = 180 litres at 600 l/h pump capacity). Thanks to its great volume, the filter features extensive backup capacity and it has a long service life (e. g. fewer maintenance intervals). The JUWEL inside filter is equipped with various filter media that facilitate biological pollutant degradation performance. The dual flow principle: A unique feature of the JUWEL inside filter is the dual flow principle in the models Bioflow M, L and XL. The water passes through the two high volume filter blocks at different speeds. This additionally optimises the biological filter process. Scientifically tested: The JUWEL filter system has successfully been tested with regard to its effectiveness in scientific long-term tests by independent institutes a number of times. All JUWEL inside filters are designed with extensive backup capacity, guaranteeing optimised filtering for top water quality. Users appreciate the inside filter’s ease of use and built-in safety: The water stays inside the aquarium!
There may be various different reasons, if your pump is unpleasantly noisy. Please check that your pump is positioned correctly, and make sure to observe the 6 to 8 week run-in period when taking your Bioflow filter into service. To ensure optimised functionality and running smoothness for your pump, we recommend that the pump is cleaned on a regular basis, and that wear parts such as the impeller and axle along with the rubber bearings, are replaced every 12 months.
In addition to the filter media fitted at the factory, JUWEL Aquarium offers a range of additional filter media. 2. If your aquarium shows increased ammonium values, you should used our filter medium “Amorax”. It quickly and effectively binds ammonium, prevents the formation of ammonia and promotes the vitality of your fish. 3. If you perceive odour formation in your aquarium, or if the water changes in colour, you should use the filter medium “Carbax”. 4. The filter medium “Cirax” provides an even greater surface for filter bacteria to settle, than the fine filter sponge bioPlus, and it thus provides for a consistent filtering effect in your aquarium. 5. If your aquarium shows increased phosphate values, you should use our filter medium “Phorax”. This medium removes phosphates from your aquarium, and it effectively reduces algae growth and promotes improved plant growth.
"BIOFLOW M/L/XL: We recommend that Carbax is used in the upper filter insert, between bioCarb and Nitrax. Amorax, Cirax and Phorax should be placed at the top of the lower filter insert. BIOFLOW SUPER: Carbax, Amorax, Cirax and Phorax can be used in the upper part of the filter basket, instead of the Nitrax sponge. Please refer to our change flyer in the download centre for information about the exact placement of our filter media."
If you are operating the EccoSkim using the filter mount on the filter itself, it is not possible to also attach the FilterGrid to the filter. However, you can attach the EccoSkim to the glass using the provided suction mount, to make room to mount the FilterGrid to the intake slots of the filter.
Yes. However, you will need to individually adjust the cut-out, rather than using the template on the back of the cover. If a FilterCover is already mounted to your filter, you can carefully enlarge the cut-out at the bottom using a box cutter to make the FilterGrid fit.
It goes without saying that the manner and the frequency of cleaning the JUWEL filter depend on the individual conditions. Our recommendations to clean or replace the media are based on average experience: Replace the white poly pad on a weekly basis. Replace the black carbon sponge approx. every month if needed. Replace the optional Carbax filter basket after approx. 2 months. Replace the green Nitrax sponge every 2 months. Replace the blue, coarse-pored filter sponge after approx. 3 months. Replace Cirax filter baskets with ceramics after approx. 12 months, Phorax after approx. 2 weeks and Amorax after approx. 3 months. Replace the blue, fine-pored filter sponge after approx. 9-12 months. Important: For safety reasons, always disconnect all devices that are operated in the water from the power grid during the filter maintenance. Never replace all blue filter media at the same time. Check the water level in the filter at regular intervals; if the water level drops, the media will need to be replaced due to the fact that they are clogged and prevent the water from flowing through them.
The impeller is the rotor equipped with a magnet in the pump. It should be replaced every 12 months in order to ensure operating quietness.
If the filter media have been clogged, the water quantity passing through the filter is reduced. The water level in the filter slowly begins to drop. The capacity of the pumps is designed in such a manner that they have sufficient reserves. Tip: Check the water level in the filter housing every week, when replacing the filter floss. If it dropped in comparison to the water surface of the aquarium, carefully flush the upper filter media or replace them.
You may find the respective information in the instructions for use in the aquarium passport. If you have misplaced your aquarium passport, you are able to access the file “compatibility chart” in our download area. Based on the size of your filter media, you are then able to identify the filter system used in your aquarium. Please feel free to contact our customer service for assistance.
The pump is arranged next to the filter media in the intake chamber of the filter housing. Advantage: Free access to the filter media simplifies the filter maintenance!
With the exception of the Eccoflow 1500 that may be installed in the filter Bioflow L/6.0 and XL/8.0 only, you may insert all JUWEL pumps into each filter. Simply keep in mind for pumps 280 and 1500 that they do not fit into the Bioflow filter. And conversely the pumps Bioflow 280 and 1500 do not fit into the filters Compact, Standard or Jumbo.

General

You can order spare parts from your specialist Juwel retailer. Find your nearest retailer in our "Where to buy" section.
Our warranty period for all parts of the aquarium is 2 years from the purchasing date. Filter sponges and fluorescent tubes T5/T8 as well as all components that are subject to normal wear, e. g. the impeller of the pump, are excluded from the warranty. The basis for the warranty is the availability of a valid proof of purchase.

LED Lighting

The Primo series features a NovoLux LED Neo White as standard. This light unit is particularly energy efficient and it meets the requirements for operating an aquarium. In order to increase the satisfaction of your individual requirements, you can upgrade your aquarium by placing up to three NovoLux LED Neo lamps in the cover.
LED lighting media have a longer service life than conventional fluorescent tubes. The NovoLux LED, MultiLux LED, HeliaLux LED and HeliaLux Spectrum have a 2 year warranty from the date of purchase.
The Primo series features a NovoLux LED Neo as standard. You can upgrade your aquarium’s light system by placing up to three NovoLux LED Neo lamps in the cover. The additional lamps can be simply attached to the cover, using the included clips. The NovoLux LED Neo can furthermore be operated with a suitable controller. Sunrise, sunset and the duration of dimming can be programmed individually.
The factory-installed MultiLux LED (from 2017 onwards) is not dimmable.
Replacing the unit with the HeliaLux Spectrum, in combination with the HeliaLux AppControl, enables individual lighting schedules and dimming curves.
The HeliaLux Spectrum is a specially developed full-spectrum LED with maximum performance. Special red, green and blue LEDs have been employed in the HeliaLux Spectrum to create intense colours and maximum contrast. They cover the full spectrum and are ideal for supplementing the light-intense white 9000K and 6500K LEDs. When combined with the HeliaLux AppControl, they enable you to adjust the lighting conditions in your aquarium to meet your requirements. In addition to sunrises and sunsets, you can easily programme lighting phases.
The HeliaLux Spectrum is only suitable for use in fresh water aquariums. It is not suitable for saltwater aquariums. We recommend the MultiLux LED with the LED lighting media Marine and Blue to provide for ideal conditions in saltwater aquariums.
The UniversalFit holder allows for the HeliaLux Spectrum also to be used in aquariums from other manufacturers.

Saltwater

Each JUWEL aquarium of the model series Lido, Rio, Vision and Trigon is equipped with a MultiLux LED comprising an LED DAY and an LED NATURE as standard. JUWEL Aquarium offers two further LED tubes for your saltwater aquarium that you can use by simply replacing the existing LED tubes. Both the LED MARINE and the LED BLUE are designed to recreate the lighting conditions of a coral reef and they specifically promote the growth of your corals. The LED MARINE with its brilliantly white 14,000 Kelvin light provides for bright conditions, while the LED BLUE creates fascinatingly deep blue tones.
The filter media filter floss, carbon sponge, fine filter sponge and coarse filter sponge that are fitted at the factory can also be used for saltwater aquariums. The optional filter media such as Amorax, Carbax, Cirax and Phorax are also suitable for saltwater aquariums. Nitrate remover Nitrax, on the other hand, should be used for fresh water aquariums only.

T5/T8 Lighting

To ensure waterproofness of your JUWEL aquarium light unit, we recommend that the fitting rings are replaced once a year. When using a T8 or T5 light unit, the fluorescent tubes should also be replaced on this occasion.
The MultiLux LED features a higher light intensity while saving up to 50 % of energy compared to conventional T5 technology. Further advantages of the MultiLux LED include a longer service life of the LED tubes, and durable light quality compared to T5 fluorescent tubes.
The T8 fluorescent tubes should be replaced every 10 to 12 months, to ensure the tubes’ luminosity. The HiLite T5 fluorescent tube should also be replaced every 10 to 12 months, with the exception of the HiLite Marine and the HiLite Blue. Those two models should be replaced more frequently, every 6 to 8 months.
It is not possible to replace a T5 HiLite fluorescent tube with an LED tube. The MultiLux light units may look identical, however, they feature different integrated control units for the fluorescent tubes’ ignition voltage. Each control units is designed for the specific light unit. If you would like to change to LED operation, you should buy a designated MultiLux LED light unit or a HeliaLux light unit. Both products are a perfect match for your aquarium and they are quick and easy to install.
Each JUWEL aquarium of the model series Lido, Rio, Vision and Trigon is equipped with a MultiLux LED comprising an LED DAY and an LED NATURE as standard. This provides for brilliant lighting and excellent plant growth. The replaceable tubes create an optimum light spectrum, while saving up to 50% of energy compared to conventional T5 light units. While the LED DAY highlights your animal and plant world with its bright and stimulating light, the LED NATURE provides for a warm and natural light that promotes photosynthesis of your plants and brings out the green tones in your aquarium.
We recommend the use of reflectors for T5 and T8 fluorescent tubes for two reasons: Reflectors increase the illumination by 100% which is particularly positive, especially in case of plant aquariums. In addition, they serve in a very convenient manner as a visor which simplifies the maintenance of the aquarium a great deal. All steps in the aquarium may be performed in a more successful and comfortable manner under full illumination. LED light units (such as the MultiLux LED, NovoLux LED, HeliaLux LED, HeliaLux Spectrum) do not require reflectors. The LED light units are already optimally adjusted to the aquariums and they have an ideal beam angle.
As the plants prefer stable light conditions, the lighting cannot be switched on in different steps.
No, you can only use T5 HiLite tubes in a T5 HiLite light unit as these are fitted with special electronic ballasts and have the correct special sockets for the tubes. T5 and T8 are not interchangeable.
The spectrum of the T5/T8 fluorescent tubes or the LED lighting media is printed on the respective packaging and you can also find it in the image gallery on the product page.
Any JUWEL Aquarium that utilises a Multilux light unit (central black bar), i.e. all aquariums of the series Lido, Rio, Vision, Trigon, Panorama and Delta, may be converted by simply replacing the old light unit with a new T5 HiLite version.
As the commercially available standard T5 tubes were only developed for general room illumination purposes, the lighting technology had to be adapted to the common aquarium dimensions in order to ensure the complete illumination over the entire length of the aquariums. As a result, we are able to completely illuminate the entire area of our aquariums with lengths of 60, 80, 100, 120 and 150 cm with high illumination.

SmartFeed AppControl

In factory default mode: After connecting the device to the power supply, it automatically enters pairing mode (LED signal: short, short, long). Now open the MyJUWEL App and follow the instructions for setup.

If the LED signal does not appear, you can manually activate pairing mode by performing a factory reset (see above).

Next, select your 2.4 GHz Wi-Fi network, enter the Wi-Fi password, and make sure you are within range of your router.
The connection is successful when the blue LED lights up continuously.
If your SmartFeed AppControl is correctly set up but still appears as “offline” in the app, this may have the following causes:
- The device cannot connect to your Wi-Fi or is out of range. In this case, the blue LED flashes briefly at regular intervals.
Solution:
- Restore factory settings:
Press and hold the control button for at least 10 seconds within 30 seconds after connecting the device to power.
The green and blue LEDs will flash rapidly – the device is now in pairing mode. Start the setup process in the app again.
- Activate Bluetooth:
Make sure Bluetooth is enabled on your smartphone.
- Keep devices close together:
Ensure that your smartphone and the SmartFeed AppControl are close to each other during setup.
On the device:

Briefly press the control button – the device will feed automatically using the preset amount (⅛). You can adjust the amount in the app.

Via the app:

Start the feeding manually and conveniently using the MyJUWEL App – with your individually set feed quantity.

Using voice command:

Use voice control via Amazon Alexa or Google Assistant with the command:
“Start feeding”
To do so, voice control must first be activated in the MyJUWEL App.
- Blue flashing (short, short, long): Pairing mode active
- Blue flashing regularly: Connecting to Wi-Fi
- Blue continuously on: Wi-Fi connection successful
- Green continuously on: Normal operation, feed chamber sufficiently filled
- Green flashing (1 second): Low feed level
- Green flashing rapidly: Mechanical error (e.g. jammed feed screw)
The SmartFeed AppControl operates exclusively on the 2.4 GHz frequency band.
Please ensure that your router is running in 2.4 GHz mode or dual-band mode (2.4 / 5 GHz).
Disconnect the device from the power supply before cleaning.
Use a soft cloth and lukewarm water – do not use harsh cleaning agents.
We recommend checking the SmartFeed AppControl for dirt about every four weeks and cleaning it if necessary using the included cleaning brush. This ensures hygienic and reliable feeding.
Yes, after setup in the MyJUWEL App, you can control your SmartFeed AppControl using Amazon Alexa or Google Assistant.

Available voice commands:
- “Start feeding” – immediately starts feeding with the predefined amount
- “Set feed quantity to X (1–8)” – adjusts the feed quantity
Note: Voice commands are currently available in German and English.
The SmartFeed 2.0 is programmed directly on the device and is ideal if you prefer simple and straightforward operation. You can schedule up to three feedings per day with individually adjustable portion sizes and intervals of 24, 48, or 72 hours.

The SmartFeed AppControl is the logical evolution of the SmartFeed 2.0 and is fully controlled via the MyJUWEL App. This gives you complete control over feeding your fish – anytime and anywhere – conveniently via your smartphone.
With the MyJUWEL App, you can schedule up to twelve feedings per day, adjust the feeding quantity in eight levels, and also feed manually. All settings can be changed flexibly – no matter where you are. Additionally, you’ll receive notifications when the feed level is low – so your fish are always reliably supplied.

Both models come with interchangeable feed screws for optimal dispensing of different types of food.
Yes, a smartphone is required to operate the SmartFeed AppControl. Setup and operation are carried out via the MyJUWEL App, which must be installed on an Apple iOS or Android device. The app guides you step by step through the setup and allows for intuitive control.

Please note: To connect with the MyJUWEL App, a Wi-Fi network operating at 2.4 GHz or dual-band 2.4/5 GHz is required. A mobile hotspot is not sufficient for this.
Please make sure that both Bluetooth and location services are enabled on your smartphone.

Important: Even if location access has already been granted in the app, the location service must also be activated in your phone’s system settings. Your location is not stored – it is only required to detect new devices within your network.

For a stable connection, we recommend placing the SmartFeed AppControl close to your router during setup.
Yes, in order for the MyJUWEL App to correctly detect and connect to your SmartFeed AppControl, location data must be enabled.

Don’t worry: this does not involve GPS data – your actual location is not being recorded.
Wi-Fi devices communicate via the names of nearby networks. According to legal requirements, this network information is considered location data because it could theoretically indicate your position. This is why the system is required to display a corresponding message.

Important to know: This data is not transmitted to our servers. It is used exclusively to enable the connection between your smartphone and the device.
Press and hold the control button for at least 10 seconds within 30 seconds of connecting the device to a power source.
If the reset was successful, the green and blue LEDs will flash quickly three times in succession.
