Calcium Reactor Contribution Calculator


This calculator estimates the amount of calcium and alkalinity that a calcium reactor contributes to an aquarium system. It should not be used immediately after setting up or adjusting a calcium reactor. Instead, wait until the system calcium and alkalinity levels have stabilized.

Note that the term "effluent" describes the water leaving the reactor. The best way to measure the effluent flow rate is with a small beaker of known volume and a stop watch.
