Contact: [email protected]
TankLog is a water-quality logging app for every kind of aquarium — freshwater, planted, brackish, saltwater, and reef.
What it does
- Add a tank and log water tests: pH, ammonia, nitrite, nitrate and temperature for every tank, plus salinity, KH, GH, calcium, magnesium and phosphate where relevant to that tank type.
- Every reading is instantly checked against ranges built for that tank type — normal, high, or low at a glance.
- Log water changes with a percentage and note; your next reminder resets automatically.
- Set reminders every 3, 7, 14, or 30 days so a water change never slips your mind.
- Track trends on 30- and 90-day charts, and back up your whole tank history to a file you control.
TankLog Pro
A one-time purchase ($4.99) that unlocks unlimited tanks, every chart parameter with 2-parameter overlay, CSV export, and multiple reminder schedules.
