Aquarium Prime

Aquarium Prime turns tank keeping into something you can measure. Add every aquarium you run — freshwater, planted, shrimp, cichlid, marine, reef or biotope — and the app works out what matters from your dimensions alone: true net water volume after substrate and hardscape, loaded cabinet weight, and the glass thickness, filter turnover, heater and lighting power your tank actually needs.

Then keep it stable. Log twelve water parameters graded against the ideal band for your specific tank type, see the trend, and get told how many days until a drifting value leaves safe range — plus the water change percentage that fixes it. A photo journal, recurring care reminders, equipment service tracking and spend and energy insights round it out, alongside twelve calculators covering dosing, RO blending, CO₂, salt mixing, substrate and more.
