Aquarium Water Calculator is a commercial desktop application developed by Fish Tank Apps to make aquarium-water preparation more accurate, predictable and repeatable.
The program calculates remineralization and fertilization recipes for different water sources and aquarium conditions, using preset or custom target parameters. The calculations include GH, KH, pH, TDS, CO₂ and plant nutrients. Its guided workflow allows aquarists to enter initial water-test results, automatically calculate a complete remineralization and fertilization recipe, and, when necessary, retest and manually adjust individual recipe components to achieve the desired parameter targets precisely.
The application is available for Windows and macOS.
