EcoQube C Maintenance Tips

EcoQube C

I'm not able to grow my plants - what can I do? 

If you want to easily grow a plant, we've found that the easiest plant to grow are green onions. All you have to do is take the head (white part with roots sticking out) and stick it straight into the black grow basket/net pot (no plant medium needed). Make sure that the roots have access to water and it should grow very well. Trim the green onions when they grow too tall and replace as needed every 2-6 months with a fresh green onion head. 

Why is my Basil not growing/what is wrong with my White sponge? (Kickstarter EcoQube only) ALL UNITS SOLD IN 2016 or later are OK. 

We have been notified by several of you regarding the white plant media disintegrating under certain conditions. We initially sourced the white plant medium to replace the brown plant medium ( which contains organic tree bark) so that the EcoQube can easily pass through different countries’ customs regulations. Here’s more resources for all the international backers out there!

The white plant medium was tested in our EcoQubes for several months but we do not yet know what conditions are causing the white plant medium to melt. The white plant medium is not harmful to the ecosystem and can be easily replaced by natural ocean sponge which can be found easily online at very affordable prices. We advise against using media like rockwool because harmful mold can easily grow on rockwool and other plant medium that stay too wet over time. Here’s an example of the natural sea sponge we recommend:

USA ONLY: Contact us for a replacement plant medium if you were a Kickstarter backer.

My PUMP/FILTER seems to have stopped working, how do I fix it? (PUMP IS CLOGGED)


1) Remove black top cover to expose what is under the plant

2) Find hex nut internal to the back compartment that is behind the water nozzle in the tank

3) Remove nut from back of nozzle

4) Remove nozzle

5) Unplug, then pull assembly of uv filter and pump up from back of case

6) Check pump for blockage of input side (algae, etc.) I used a new toothbrush and cleaned the circular intakes on the pump

7) Check tubing from pump to nozzle outlet - I used a couple pipe cleaners and made mine spic and span (there was build up of crud in them)

8) Replace and power up all the things

Will my EcoQube C work without the basil growing?

The EcoQube C filter is built similar to a standard aquarium, so it will work without the basil growing. However, the basil takes out the waste created from the fish and food in the system, eliminating the need to change the water. So if the basil is not growing, a 25% water change (with Reverse Osmosis water, or high quality bottled water) is recommended once a week if there is fish or any livestock in the EcoQube.

Can I use tap/public water to fill my EcoQube C?

We do not recommend using water from a faucet to fill your EcoQube, unless you filter it properly. We recommend using Reverse Osmosis water, or high quality bottled water to start your EcoQube C, or to top off evaporated water. Tap/public water can contain chlorine and other harmful chemicals that can cause harm or death to any livestock in the system. 

Which fish thrive the best with the EcoQube C?

We highly recommend keeping 1 betta/siamese fighting fish because it thrives in room temperature water. Other fish like guppies, endlers, white cloud mountain minnows, zebra danios can be kept in the EcoQube C as well but each require a specific set of water parameters. We also recommend amano algae eating shrimp and algae eating nerite snails to keep the ecosystem pristine.

Does the EcoQube C need supplemental light like sunlight?

Sunlight is what usually causes imbalances in an aquarium or ecosystem. Sunlight has a lot of energy and can cause algae growth due to imbalances in the ecosystem. Keep it away from sunlight and your EcoQube C will never have green algae.

What is the size of the EcoQube C?

The EcoQube C is about 7.8 inches by 7.8 inches by 7.8 inches and holds about 1.5 gallons in volume.

Does the EcoQube C need the compact UV sterilizer?

The EcoQube filter was originally designed with commercial use in mind so that it could be scaled for food production and run clean water through the plants that would be harvested. But a typical small aquarium will not require UV sterilization although having it helps keep the water extra clean by acting as a buffer for mistakes such as overfeeding or too much sunlight exposure which causes bacterial and algae growth. You are always more than welcome to use the UV sterilizer as an attachment.

Why can't we eat the plant growing out of the EcoQube C?

The plant is used for filtration. If removed the main filtering mechanism on the EcoQube C will be removed. Aquarium products are also not made for food consumption. Most people will end up using aquarium fish food, dechlorinator and other products recommended by local fish stores that can be toxic.

Will you offer add-ons like the plants, wood and rocks shown in the photos and videos?

Yes! Due to the high demand of the original EcoQube, add-ons such as those listed above are sold on our website, 

Does the EcoQube C consume a lot of energy?

The EcoQube C will consume less than 7 watts when the pump, light, and UV is being used. The UV only needs to be on for 2 hours a day while the light only 7 hours.

Does the EcoQube C work with saltwater?

The EcoQube C was designed and tested for freshwater but it may work with a small mangrove in the filter. No guarantees though.


How exactly does the automatic timer function work?

The automatic timer feature will turn on the white, LED grow lights for 7 hours, once a day.To activate the automatic timer, press and hold on the timer button (the clock with a 7 in it) for 3-10 seconds. If you have the inline controller, a small, blue indicator LED will light up just above the button when the timer is active. If you have the remote control, the LEDs on the light panel will blink once to indicate that the timer is now active. The timer is set to turn on at exactly the time you activate it, so if you activate the timer at 7:00 AM, your lights will turn on from 7:00 AM to 2:00 PM every day. NOTE: If the timer is active, the remote/inline controller WILL NOT work for other functions, you need to disable the timer by repeating the same process to turn them on, or unplug the light, plug it back in. 


How many fish can the aquarium hold and what species are recommended?

We would suggest starting off with a single betta fish. Bettas are great fish for beginners as they are very sturdy and adaptable. Just make sure to keep it solitary, they don't play nicely with others! Otherwise start off with two white cloud minnows or zebrafish and, if you’d like, slowly adding more as your plants grow. If you’re keeping the aquarium in a warmer area (75͒ room temperature), you can easily keep smaller tropical fish, like guppies, scarlet badis, and many others. If you're looking to put more fish in, please keep in mind the compactness of the EcoQube. Give them some room to swim around. 


What plants are recommended for the EcoQube C?

We would highly recommend green onions, followed by basil and mint. We've found that green onions are the easiest to grow. If you're looking for something a little more challenging, you can try basil or mint. Inside the aquarium, we recommend EcoQube owners to include aquatic plants, like Java Ferns, aquatic mosses, and Anubias. The more plants there are in the EcoQube, the easier it will be to maintain.

How do I grow green onions in the EcoQube C?

All you have to do is take the head (white part with roots sticking out) and stick it straight into the black grow basket/net pot (no plant medium needed). Make sure that the roots have access to water and it should grow very well. Trim the green onions when they grow too tall and replace as needed every 2-6 months with a fresh green onion head. 

Do any plants come with the standard Ecoqube C kit?

The standard Ecoqube comes with basil seeds to grow on top of the aquarium as part of the aquaponics cycle. No aquatic plants are included with the standard kit. However, they can be purchased to be included with your kit in our shop section. 

Can any type of soil be used for growing the plant at the top section?

In the filter section of the EcoQube, we have a special reticulated foam formulated to germinate/grow seeds. However, for our international backers, we recommend using a hydroponic starter plug, expanded clay pebbles or a natural sea sponge to germinate seeds. Rockwool plugs can be used, however, it has a tendency to generate harmful molds when constantly exposed to water, as it would be in the EcoQube.

Will I need to water the plant up top?

No, using the aquaponics system, your plant will be constantly receiving nutrient rich water via the filter.


Is there a video I can watch to learn about maintenance?

Yes, this one has some helpful tips:

How do I maintain my aquarium if I am away for an extended period of time (i.e. vacation, business trip, etc.)?

Make sure someone tops off your aquarium at least once a week. Maintain the water level above the water chute on the filter. In a developed ecosystem, most fish can be left unfed for about 5-10 days, but the filter cannot run dry for more than a few seconds.

How much dechlorinator should I add to the EcoQube?

You will only need a small amount, roughly 2 to 3 drops will work perfectly.

Will I ever have to change the filter?

The filters do not need to be changed unless you are replacing the plant inside the filter itself. However, every ecosystem is different, and depending on the bioload (amount of livestock) and debris, the filters can get clogged. In that case, simply remove the filter cover, take the sponge out, and rinse the sponge in conditioned water. Remove any debris you see on the bottom of the filter, and place the sponge back into the filter.

So I don’t need to change the filter. Will I still need to feed the fish?

Yes! Your fish need to be fed once a day but only in the amount that they can eat within 30 seconds. Additional food will pollute the ecosystem.

How would I replace the LED light if it were to stop working?

The high quality LEDs are rated for 10,000 hours. However, once in a while, a section of the LEDs can go out due to circuit breakage or disconnecting wires. In this case, the entire LED unit would have to be replaced. If it’s still under ADI’s 12-month warranty, please email us at for a replacement!

Is there a certain water level that must be maintained?

Water level must be maintained above the water spout at ALL times.

UV Sterilizer

Is the compact UV sterilizer necessary?

We originally built the Aquaponics Filter in the EcoQube with commercial use in mind so that it can be scaled for food production and run clean water through plants we harvest from the filter. Typically, a small aquarium will not require UV sterilization, although it helps keep the water extra clear and clean by acting as a buffer for mistakes, such as overfeeding or exposure to too much light, a cause of bacterial and algae blooms. However, the compact UV sterilizer can be added on as an attachment.

How long does the compact UV sterilizer last?

The UV light is the first-ever 265 nanometer LED used for water sterilization in aquarium filters and is rated for over 10,000 hours! It only needs to be on one hour a day to clean your EcoQube, so it should last a lifetime.

How do I install the UV sterilizer?

If you ordered the UV EcoQube C, your UV sterilizer will come pre-installed.


I’m an international customer, what is the voltage for the power cord? Do I need an adaptor?

If you are outside of U.S.A., you will need to purchase an adaptor. Voltage is a wide range 110V AC- 240V AC input.

Is there an international shipping fee?

Yes, the international shipping fee is an additional $18.
