Calcium Reactors

Calcium reactors are a powerful solution for aquarists who want to maintain stable calcium and alkalinity levels in reef aquariums. These systems dissolve calcium carbonate media using CO2 to create an effluent that replenishes essential calcium and alkalinity that is consumed by corals and invertebrates.

Our calcium reactor collection includes units sized for aquariums up to 500 gallons. When set up properly, calcium reactors offer consistency, less frequent media changes, and reduced effort in maintaining water chemistry.
