Calcium Reactor

A calcium reactor is a simple, convenient solution used to maintain calcium and alkalinity in a reef aquarium. They require little maintenance after the initial setup and are almost a necessity for tanks heavily stocked with stony corals, where calcium and alkanlinty demands are high.

To remove any guesswork, weâ??ve assembled several packages that include everything youâ??ll need: a calcium reactor, a Co2 regualtor / Calcium Media and Co2 Bottle.

You can controller by the Co2 Regulator  + PH Controller + Calcium Reactor to controller the KH
