Aquarium Tracker: Water Tests

Aquarium tracker for your water tests: log pH, ammonia, nitrite, nitrate and other water parameters for each fish tank by hand from your own test kit, then tap a chart point to read the value, date and notes behind a trend. ▶ KEEP YOUR TEST HISTORY AND BACKUPS • Record repeat water tests for multiple tanks, with the date, time, units and notes kept with each test. • Write verified backup creates an archive with a manifest and checked data parts, reads the files back before offering it for sharing and keeps your three most recent backups. • Choose backup opens a Restore preview before you merge anything. See how many entries and previous deletions it holds; missing parts are named and an incomplete backup cannot be merged. • Merge this backup keeps newer records and remembers previous deletions, so an older backup does not bring deleted records back. ▶ READ THE VALUES BEHIND THE CHART • Open Log, choose a parameter and tap a chart point to see its recorded value, date and notes. • Compare a second parameter across the same dates. Each series has its own numeric scale; historical units and ammonia bases stay separate. • Target ranges appear as bands when units match. Records below the chart lists tests, water changes, fishless cycle checks and completed tasks by date; delete a mistaken water change or check after confirming. ▶ A DASHBOARD FOR EACH TANK • Switch between named tanks in Tanks and see the latest readings beside the aquarium illustration and test-tube gauges. • Log pH, KH, GH, ammonia, nitrite, nitrate, phosphate, calcium, magnesium, salinity, temperature and TDS. Parameters with targets or recent readings come first; More parameters shows the rest. Leave unmeasured values blank. • Set the test time with Now, Yesterday or Choose date. Values are shown rounded to readable decimals for each parameter, and switching units converts from your original entry. • Edit Target ranges and Your kit steps to match the numeric steps on your own kit chart. ▶ PLAN ROUTINE CARE • Add care tasks with a due date and a repeat interval. Mark a task Done to keep its completion record and move its next due date forward. • Enable local reminders for the tasks you choose. If notification permission is denied, the task is saved without a reminder. • Water-change estimate fills in the tank’s latest nitrate reading and uses the percentage changed and replacement concentration; Record water change adds it to Records. Label dose calculator uses the label amount, label water volume and volume actually treated. ▶ GOOD TO KNOW • Readings come from manual numeric entry using your own test kit. • Records are stored on your device. Backup sharing opens the device share sheet; restoring requires a backup you select. • Salinity readings retain their entered ppt or SG units and instrument details. • Target presets are editable starting guides, not species-specific care advice. Water-change estimates use mixing arithmetic and do not predict pH or buffer effects. • Replacement concentration starts at zero: enter your source-water measurement when known.

Tank Log’s interval between opening ads when you come back is now remotely configurable, so it can be tuned without updating the app. Tanks, tests and tasks are not affected.
