Aqua Medic Reactor 100 for Aquariums
The Aqua Medic Reactor 100 is a passive internal pressure diffuser for introducing CO2 into the aquarium. It does not need a pump for operation, you can simply mount it inside the aquarium near the bottom. The carbon dioxide is forced through a ceramic disc, which produces fine bubbles that dissolve as they rise to the surface.

I installed the Reactor 100 in my planted tank and noticed a clear improvement in plant growth. The bubbles are fine and even, and it works without any additional equipment. Easy to set up and has been running smoothly for over two months.
