CO2 Diffusers can be used alongside CO2 bottles and CO2 sets to spread the release of bubbles through the water. It is important to make sure that the diffuser is the right size for your preferred CO2 flow rate. Too small and the bubbles will simply rise to the surface and not disseminate the CO2 throughout the water properly.
The Aqua Medic Reactor 1000 is a hermetically sealed unit for introducing CO2 into large aquariums. Its robust mounting plate means that it can be mounted to either the outside of the aquarium or inside the aquarium cabinet.
The Fluval CO2 Ceramic Diffuser is tailor made to allow the highest amount of CO2 to be diffused directly into the aquarium water.
