How it works

In a reef tank, calcareous organisms like corals and clams along with calcareous algae, such as coralline algae, utilize the calcium dissolved in the water as one of the components to build their skeletons or shells. To keep a constant level in our reef tanks we need to supply calcium into the water column. One of the ways to accomplish this is the use of a calcium reactor. A calcium reactor, in conjunction with CO2 system, dissolves calcium-based filter media inside the reactor to replenish calcium and other minor elements in your aquarium water. For tanks with a high calcium demand, a calcium reactor is an invaluable tool that eliminates the need for 2 parts dosing. 

What's Needed to Run a Calcium Reactor

1. Calcium Reactor 
2. CO2 Regulator w/ Solenoid. (Standard or Electric Carbon Doser) 
3. CO2 cylinder. - Standard Tank 
4. Check Valve - Basic valve is included in this package.
5. Calcium Reactor Media
6. pH Controller or Aquarium Controller with pH probe.
