CO2 bubble counter with built-in non-return valve

The bubble counter with check valve is a must have for any aquarium with CO2 equipment. Using a bubble counter, the user can accurately estimate the CO2 injection rate by counting how many bubbles pass the counter per minute.
Mountable both inside and outside the tank, a modern small and inconspicuous bubble counter, easy to view from all sides through the transparent plastic.
The non-return valve prevents water from the aquarium from flowing back into vulnerable and expensive CO2 equipment.

Before use, fill the bubble counter with water using a small syringe and a piece of air hose and attach the bubble counter inline between the CO2 supply and the diffuser / reactor.
