Reef Octopus CR-140 Calcium Reactor– for aquarium up to 800 liter


Quality, design and affordability define the Octopus Calcium Reactor series. Available in 2 different models that feature reverse flow water current for maximum water and Cocontact time with the coral media.All 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 alkanility, calcium and trace elements, consider adding a Reef Octopus calcium reactor to your aquarium system. 

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.
