CR100 4 inch Calcium Reactor

Introducing the Reef Octopus calcium reactor series: the perfect balance of quality, design, and affordability. With three models featuring reverse flow water current for maximum water and CO2 contact time with the coral media, these reactors are equipped with PH probe holders and built-in bubble counters to monitor PH levels and CO2 drip rates. Meet your aquarium's alkalinity, calcium, and trace element needs with ease by adding a Reef Octopus calcium reactor to your system. How it works: The reactor chamber is filled with aragonite, the crushed skeleton of ancient hard corals, and aquarium water is pumped through alongside pressurized CO2. The resulting acidic environment dissolves the aragonite and releases essential minerals and trace elements used by corals for growth. Plus, this automated system requires minimal maintenance for maintaining or increasing calcium levels.
