The CO2 Count Diffuser by DOOA is of great help when supplying the aquarium with the important plant nutrient CO2. This is especially important in aquascapes and plant aquariums to ensure a good plant growth. For a great solubility of the CO2 in the water it is advisable to atomize the CO2 bubbles. This atomization is ensured by the membrane that is included in the CO2 Count Diffuser. Furthermore, the correct adjustment of the input should be controlled and adjusted. In most cases, for this purpose a separate bubble counter is needed. Not so when using the Count Diffuser. Here the bubble counter is included within the diffusor and thus, the two important components are joined in one object.

We recommend to use soft silicone tubing to connect the glass ware in order to reduce the risk of glass breakage. The piece of hose used should be kept as short as possible in order to avoid unnecessary CO2 losses.
Silicone hose is not pressure resistant and therefore can not be used for connection to the pressure regulator.
