Reef Octopus Classic CR-100 Calcium Reactor

Reef Octopus CR-100, quality, design and affordability define the Reef Octopus Classic Calcium Reactor series. Available in 2 different models that feature reverse flow water current for maximum water and C02contact time with coral media.

Reef Octopus CR models come with PH probe holders to monitor Ph levels in the main reactor chamber and built in bubble counters to monitor Co2 drip rates. To help you meet the challenging task of maintaining alkalinity, calcium and trace elements, consider adding a Reef Octopus calcium reactor to your aquarium system.

How Calcium Reactor works

A calcium reactor is essentially a chamber full of Aragonite which is natural form of carbonate mineral or commonly known as crushed hard corals. Aquarium water is circulated through this chamber along with carbon dioxide (CO2). The CO2 lowers the pH in the chamber to an acidic level which dissolves the carbonate minerals into the aquarium water. In addition to dissolving the carbonate minerals, this process also dissolves nearly all the minerals and trace elements the coral needed to grow. Automated Calcium and Alkalinity supplementation – When set up properly with external controller and probe. These perimeters can be pre-set with very little monitoring and maintenance.
