ISTA – CO2 DIFFUSER

This acrylic Co2 diffuser with its built-in bubble counter and check valve is very compact and inconspicuous in the aquarium.

Thanks to its replaceable membrane, it is not necessary to change the whole diffuser and cleaning the membrane is very easy.

With the help of the built-in bubble counter the Co2 supply is very easy to adjust. The integrated non-return valve prevents the aquarium water from flowing back.
