CO2 System BIO from Tropica is a CO2 fertilisation system for improved plant growth in aquariums from 60 litres. Especially in a very planted tank, a CO2 system ensures healthy and strong plants. The supply of CO2 takes place exclusively via a biological process. The necessary mixing of the biomass is simple and easy, and the mass is also completely biodegradable and can easily be disposed of after use. With the Tropica CO2 System BIO Refill the system can easily supply an aquarium with CO2 for another 60 days.


  • For a better plant growth
  • Inexpensive alternative CO2 supply
  • Sufficient for approx. 60 days
  • Easy and safe to use
  • Simple to refill with the little Activator Refill bags


Put 300 ml of warm water in the bottle. Approx. 50°C.
Place the lid without the vent and shake the bottle vigorously for one minute or until the contents are thoroughly mixed.
Then leave the bottle at room temperature for at least 24 hours until the contents have turned into a solid gel.
Meanwhile, place the CO2 diffuser in clean water to soak.

Wait 24 hours!

Add one portion of Activator to 200 ml of lukewarm water at max. 35°C.
Let the mixture sit for 5 minutes and then stir until the activator has completely dissolved in the water.
Then pour the mixture into the bottle.
Insert the seal into the cap with the vent and place it on the bottle.
Attach one end of the air hose to the bottle and the other end to the CO2 diffusor.
Place the CO2 diffuser in the aquarium.
Now wait until the CO2 production starts. Depending on the temperature, this usually takes a few hours.

The set is now installed and with Activator Refill you can produce up to 60 days of CO2.
