Affordable complete CO2 system
An affordable CO2 system for an aquarium where beautiful plant growth is desired. CO2 fertilization is virtually indispensable in a fully planted aquarium with more difficult species. CO2 is the most important source of nutrition for aquarium plants. Plants grow much better if CO2 is added to the aquarium. This complete CO2 set has been specially put together by us with top-quality products. Easy to use and a sustainable step towards better plant growth!
Suitable for an aquarium from 0 to ??? Litre. The limiting factor is the CO2 diffuser. It must have sufficient capacity to dissolve the CO2 in the water. With the optional CO2 diffuser bowl 30, this CO2 set is suitable for an aquarium up to approximately 200 liters. Do you have a larger aquarium? Then the inline CO2 atomizer is a better choice or choose a different diffuser on the CO2 diffuser page.
Complete CO2 set with all the necessities for adding CO2 to an aquarium. Add CO2 without any fuss and easy for everyone to connect.

More information about the accessories
CO2 pressure regulator with pressure gauges and fine adjustment
The supplied CO2 pressure regulator has 2 manometers. The bottle pressure can be read on one meter to see how full the bottle is, and the working pressure can be read on the other meter. The needle/dosing valve allows this to be set very accurately and a precise amount of CO2 can be dosed to the aquarium. The pressure regulator is also protected against overpressure. The CO2 pressure regulator fits almost all refillable CO2 bottles with an external thread and has a so-called DIN 477 thread (European standard).
CO2 Solenoid valve for night shut-off
The CO2 solenoid valve can be connected to a timer in the system. This means the CO2 system can be turned off at night. The CO2 solenoid valve can also be connected to a PH controller for use in combination with a PH-controlled CO2 system.
CO2 bottle
The supplied CO2 bottle is full and refillable. Equipped with carrying handle. The 2kg CO2 bottle can be placed upright. The 500 gram bottle has a round bottom, but can be hung on the carrying handle, for example. (CO2 type EWG-NO. 204-696-9)
CO2 bottle | Dimension (Hx⌀)
| Aquarium contents | Consumption 60 L aquarium*
| Consumption 300 L aquarium* |
0.5kg | approx. 45 x 5 cm | <60L | ~10 months | ~2-3 months |
2kg | approx. 49x 12 cm | > 60 L | ~40 months | ~8-12 months |
* Estimated consumption is highly dependent on various factors. Actual consumption can vary greatly.
CO2 hoses and check valve
High-quality black CO2 pressure hose per meter (max. 20 bar) is supplied for the connection between the pressure regulator and the solenoid valve. For the connection of the solenoid valve to the ADA CO2 Check Valve and CO2 diffuser, CO2 Hose (Flexible) is supplied per m (max. 2 bar). The high-quality ADA check valve prevents water from siphoning to the solenoid valve and pressure regulator.
CO2 Diffuser
The CO2 diffuser determines whether sufficient CO2 can be dissolved in the water. For example, the Bowl 30 is suitable for an aquarium of 80-200 liters. If the aquarium is larger, a larger sparkling surface is required or, for example, the Inline CO2 atomizer. Or choose another CO2 diffuser from the range: CO2 diffusers .
CO2 bubble counter
The CO2 bubble counter is a useful product to see how much CO2 is now being added to the aquarium. It helps adjust the dosage. This can be done in combination with measuring the pH or looking at the color of the water CO2 checker (optional). With a CO2 Bubble Counter Regular, the number of bubbles can be counted up to approximately 4 per second. The CO2 Bubble Counter Spiral. This makes it easier to count a larger number of bubbles per second. Exactly how many bubbles are needed for the aquarium depends on various factors such as water volume, lighting, water parameters, amount of plants, etc. A reasonable starting point is 1 bubble per second per 50 liters of water volume, but as mentioned, it will depend greatly on the situation.
