Fluval Ceramic CO2 Diffuser


2 in stock

The Ceramic CO2 Diffuser effectively dissolves CO2 into the aquarium, which is vital to the health and condition of your plants.

My new ceramic CO2 diffuser disc is emitting large bubbles, rather than a fine mist. Is this normal?

Yes, new ceramic CO2 diffuser discs can take up to a week to begin emitting pressurised CO2 in a fine mist. It’s normal to see larger bubbles for the first few days of operation.
