AquaCalculator

AquaCalculator joins reef chemistry arithmetic to the record that gives those numbers meaning. It can document water measurements, photographs and livestock, then calculate salt needed for a water change or salinity correction and estimate additions for calcium, alkalinity, magnesium, nitrate and phosphate. Support for numerous salt mixtures makes the mixing workflow more specific than assuming every brand has identical composition. Editions are available for major desktop and mobile systems, with cloud synchronization for people who maintain the same aquarium from more than one device.

A product profile and a logged test are still estimates. Salt composition can vary by batch or mixing method, hobby tests have finite resolution, and the real system volume may be smaller than the glass dimensions. Cloud synchronization also means users should review the account and backup terms before making it their only record. AquaCalculator is most useful for preserving trends and checking a planned adjustment. Large salinity or major-ion corrections should be divided, measured again and evaluated against the animals rather than executed solely because the application returned a quantity.
