Replacement Ceramic Membrane for IO Stainless Steel Series Diffuser and IO Acrylic Series Diffuser Two different sizes; Small for aquariums below 40 gallons Large for aquariums above 40 gallons Note: Please allow the replacement membrane to soak in the aquarium water for at least 2h before pressurizing the diffuser. In the beginning, the diffuser will produce large bubbles around the ring. Over the first 24h of use, all the ceramic pores will fill with water, and the bubble size will decrease to the optimal size. CO² systems are essential for successful aquascaping. This enables aquatic plants to have greater access to Carbon dioxide, which allows a greater selection of aquatic plants to grow well in the tank. So, what's in a CO2 System: CO2 cylinder, CO2 Regulator with attached solenoid and bubble counter, CO2 high-pressure tubing, CO2 diffuser, and check valves.
