At AquaCave, we offer some of the best selection and best prices on
Geo calcium reactors and Geo kalkwasser reactor
for you marine, reef, and freshwater aquarium.
The world famous GEO calcium reactors.
Our reactors are fabricated using only the finest cast acrylic materials and high quality fittings. Designed with the user in mind, we feel these are by far the easiest reactors on the market to install, operate and maintain. Bottom up flow of water captures free CO2 and draws it back into the pump. This means less gas in the reactor and less gas in the effluent. There is no need for a second single pass chamber with our design.
These reactors include all of the fittings and tube required for normal installation. The user will need to supply the media, CO2 equipment and feed pump.
