Store description excerpt

Track your aquarium's water quality and never miss a maintenance day. Simple, focused, and built for every type of tank — freshwater, planted, saltwater, or outdoor. 【Log Your Water Quality】 Record pH, temperature, GH, KH, ammonia, nitrite, and nitrate. Add up to 5 custom parameters. Your last reading is shown as a hint while you type, so entry is fast. 【Visualize Trends】 See parameters on a clean graph over 7, 30, 90 days, or all time — with the ideal range highlighted so you can spot problems at a glance. (30-day+ graphs require Pro) 【Maintenance Reminders】 Set repeating tasks for water changes, feeding, fertilizing, filter cleaning, CO2 refills, and more. The home screen shows "next maintenance in X days" for every tank. 【Reagent Timer】 Built-in 2, 5, and 10-minute countdowns — no more guessing when your test kit is ready. 【CSV / ZIP Export & Import — Free】 Export water records as CSV, or back up tanks, photos, logs, and schedules as a ZIP. Import the same files anytime — free for everyone. 【TankDiary Pro — One-Time Purchase】 • Register more than one tank • View graphs beyond 7 days (30 / 90 / all-time) No subscription.
