Some of the largest reef display have enormous demands for calcium and alkalinity to promote their massive coral and clam growth. Such high demands for these parameters led us to create the MRC Commercial Calcium Reactor line. These units use a much larger reaction chamber; as the model size increases, additional chambers are added to increase buffering and dissolution capabilities.

MRC Pro Calcium Reactors are designed and fabricated to meet the immense demands from commercial and large scale systems. Our sturdy construction combined with the MRC spray bar technology results in the perfect solution for the demanding aquarist.

All MRC Pro Calcium Reactors include the MRC spray bar, ph probe holder, feed hose lines and a Blueline recirculation pump.
