Basic set jbl proflora co2

CO2 fertilization kit (without bottle) for optimum supply to all plants in freshwater aquariums from 40 to 300 l, preventing algae. Easy installation: screw the pressure reducer onto the bottle (not supplied), connect the hose to the bubble counter/check valve and the diffuser. Set the number of bubbles - done. For aquarists who already own a CO2 cylinder. No hose slippage thanks to screwed hose connections, non-return valve prevents water from entering the bottle. Correct CO2 concentration in the aquarium water is checked on the CO2/pH Permanent test display provided and can be readjusted if necessary. Includes: pressure reducer, 3 m hose, bubble counter with non-return valve, ceramic diffuser, permanent test with reagents.
