CO2 fertilization kit (without bottle) for optimal supply to all plants in freshwater aquariums from 40 to 300 l, preventing algae.

Easy setup: screw the regulator onto the bottle (not included), connect the hose to the bubble counter/check valve and the diffuser. Set the number of bubbles - done.

For aquarists who already have a CO2 cylinder. No slipping of the hose due to screwed hose connections, non-return valve prevents water from entering the bottle.

The correct concentration of CO2 in the aquarium water is checked on the supplied CO2/pH Permanent test display and can be readjusted if necessary.

Included in delivery: pressure reducer, 3 m hose, bubble counter with check valve, ceramic diffuser, permanent test with reagents.
