About
Reef Salt Calculator is designed for marine aquariums, reef tanks, and small saltwater tanks. It helps estimate salt dosage, water change volume, and salinity changes after top-off or maintenance. Core features include tank volume calculation from dimensions, sea salt grams for a target salinity, reverse water change calculation from current and target salinity, maintenance logs for water changes, salt additions, top-off, and measurements, plus saved tank templates and salt mix parameters. All data stays on the device for long-term offline use.
