Unlock Reef Vitality: VarioS CR220 9-inch Calcium Reactor
Quality Calcium Maintenance for Demanding Reef Systems
The VarioS CR220 DC Calcium Reactor is perfectly capable of meeting the challenging task of maintaining alkalinity, calcium, and trace elements in a demanding reef system. Quality, design, and controllability define the Reef Octopus VarioS Calcium Reactor series. Available in three different models, they feature the new VarioS variable speed pump and reverse flow water current reactor design to maximize water and CO2 contact time with the media. All models come with a 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 the VarioS CR220 9-inch Calcium Reactor 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 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.
