CR140 5.5 inch Calcium Reactor

The Reef Octopus calcium reactor series combines quality, design, and affordability. Featuring three different models with a reverse flow water current for optimal contact time with the coral media, each model includes PH probe holders and built-in bubble counters. To effectively maintain alkalinity, calcium, and trace elements, consider incorporating a Reef Octopus calcium reactor into your aquarium system. The reactor utilizes aragonite media to dissolve calcium and other minerals and trace elements, with the help of pressurized carbon dioxide and automated supplementation. Proper setup and usage of the calcium reactor can result in maintained or increased calcium levels with minimal maintenance.
