Acuario Manager

Aquarium Manager is the complete companion for your fish tank — marine reef or freshwater. Track water parameters, care for your fish and corals, and keep your aquarium healthy. It works fully offline and your data stays private on your device.

WATER PARAMETERS Log and chart pH, KH, GH, salinity, ammonia, nitrite, nitrate, phosphate, calcium, magnesium and temperature. See trends over time and get an alert when a value goes out of your target range.

FISH, CORALS & INVERTEBRATES Manage your aquarium animals with a built-in species guide: reef fish, freshwater fish, corals and invertebrates. Check care needs and the symptoms of common diseases.

CALCULATORS & DOSING Salt mix, water changes and dosing calculators for KH, Ca and Mg. Get the numbers right without guessing.

NITROGEN CYCLE Follow the nitrogen cycle and know exactly when your new tank is ready for fish.

PHOTO JOURNAL Watch your aquarium evolve month by month with a before-and-after photo comparison.

REMINDERS & MAINTENANCE Feeding, maintenance, night and emergency routines step by step, plus reminders for water tests and equipment checks.

WORKS OFFLINE — NO ACCOUNT NEEDED Everything works without an internet connection and your data lives only on your device. Create a free account only if you want to back it up to the cloud and use it on another device.

Perfect for beginners and experienced aquarists: reef tanks, saltwater, freshwater, planted tanks and nano tanks.
