Description:
Aquarium fish planted tank CO2 bubble counter with check valve

The bubble counter is indispensable with any CO2 setup system because it helps to count the amount of Co2 injected. Excess Co2 levels will lead to a sudden drop in pH level & cause severe stress to your fish. On the other hand, the underdose of Co2 will affect the growth of your plants. When the counter is set up, you can count the number of bubbles per second to estimate on the Co2 injection rate.
