CO2 Systems

Carbon dioxide or CO2 is one of the most important water parameters in the aquarium, along with temperature, pH value and water hardness. As part of photosynthesis, CO2 is essential for plant growth. In turn, high CO2 concentrations can be dangerous for fish. Among others, in order to establish and maintain a perfect biotope balance, reliable devices for CO2 regulation are needed.
The CarbonDoser® is an electronic CO2 valve for a targeted and very precise CO2 supply in freshwater aquariums or calcium reactors for sea water. It has an electronically controlled valve that produces one CO2 portion/ bubble every 0.1 to 10 seconds.
The advantages:
The CarbonDoser® replaces a CO2 valve and a bubble counter, and additionally ensures stable, precision CO2 dosing with guaranteed safety.
In freshwater — especially aquascaping — the CarbonDoser® is an indispensable tool for providing the perfect CO2 dosage regulation to optimize plant growth without laborious CO2 adjustment.
In seawater — especially reef systems - it allows the convenient and risk-free use of a calcium reactor to maintain the biotope balance.
The CarbonDoser® is delivered with very detailed instructions for use, quality non-return valve, all necessary hoses and a 12V power supply.
