Calcium Reactor Media

Calcium is the building block of all stony corals. Inadequate calcium levels in aquarium water inhibits coral growth. Calcium reactors provide a steady supply of calcium to your reef aquarium. Reactors require the use of calcium-rich media in order to function properly. A quality calcium reactor media will dissolve and release calcium and alkalinity into the water. The calcium media must also allow the free flow of water through the reactor so it does not clog with debris. We offer proven reactor media from Two Little Fishies. Reborn calcium reactor media is harvested from a sustainable source in the Western Pacific Ocean. The media is available in course and fine sizes for use in any type of calcium reactor.
