The Octopus calcium reactors operate by dissolving the aragonite within the reactor chamber. The aragonite dissolves because of the lower pH maintained inside the reactor tube caused by the injection of CO2. The effluent or excess water is high in calcium and alkalinity, and should be between 6.6 pH and 7.0 pH. Please have a pH test handy or have a pH monitor.

DO NOT LIFT A FULL REACTOR BY THE EXTENED FLANGE AREAS.

The reactor comes disassembled for shipping. (See the calcium reactor diagram) Failure to follow the assembly instructions could cause your reactor to leak. Place the reactor as close to your sump as possible, the shorter the hoses the better.
