Coralife Calcium Reactors
The Coralife Calcium Reactors come complete with a self priming external pump. However, you will need to also purchase reactor media, and a CO2 system is recommended. We offer the Aqua Medic Hydrocarbonate Reactor Media and a number of CO2 systems. The Coralife Calcium Reactor does include a CO2 Bubble Counter and CO2 Check Valve, so you will not need to purchase those items when purchasing a CO2 system.
