VarioS CR220 DC Calcium Reactor

The VarioS CR is perfectly capable of meeting the challenging task of maintaining alkalinity, calcium and trace elements on a demanding reef system. Quality, design and controllability define the Reef Octopus VarioS Calcium Reactor series. Available in 3 different models that feature the new VarioS variable speed pump and reverse flow water current reactor design to maximum water and Co2contact time with the media. All models come with PH probe holder(probe and PH controller sold separately) to monitor Ph levels in the main reactor chamber and built in bubble counters to monitor Co2 drip rates.

How it works

A calcium reactor is essentially a chamber full of aragonite, which is the crushed skeleton of ancient hard corals. Aquarium water is pumped through this chamber along with pressurized carbon dioxide (CO2). The CO2 lowers the pH in the chamber to an acidic level which dissolves aragonite media into the aquarium water. In addition to dissolving the calcium, this process also dissolves nearly all the minerals and trace elements the coral used in order to grow.

Automated Calcium and Alkalinity supplementation – When set up properly and used correctly, a calcium reactor can maintain or increase calcium levels with little to no maintenance.
