The CO2 Mini Counter by DOOA is a CO2 bubble counter made of high quality glass. It serves in monitoring the CO2 input.
The supply of CO2 and controlling the correct input is especially important in aquascapes and plant aquariums to ensure a good plant-growth while avoiding to hurt the animals within the aquarium. This control is possible by observing the CO2 counter and adjusting the number of bubbles according to the needs of the aquarium. We suggest to additionally use a drop checker to ensure the correct number of bubbles has been established.
The included check valve by ADA does not safeguard your CO2 supplying system but prevents water from leaking from the bubble counter.
