A reactor to supply dissolved calcium and calcium bi-carbonate ions to reef aquaria up to 100 gallons

The Calcium Reactor 400 is a completely sealed system operating at a very low flow rate. Within the reactor, calcium and calcium bicarbonate ions are released by the controlled dosing of CO2 gas. This provides the calcium hydrocarbonate that hard corals require to build their exoskeletons

The filter can be installed in almost any position, inside or outside the aquarium or the cabinet. To provide water flow we recommend our Dosing Pump SP 3000.

The reactor is filled with Hydrocarbonate - a pure form of calcium carbonate with an extremely low phosphate level.

For optimum control and the most economic use of the CO2 gas, we recommend the reactor be used in conjunction with a pH controller or a pH computer. The reactor is already equipped to accept our specific pressurized electrode.

Dimensions without electrode - 5.8" x 4" x 14.5"
