## What is Aquarium Water Tracker?

Stop guessing if your tank is healthy. Reef turns every water test into a clear picture of what your fish, coral, and invertebrates actually need. Log parameters, spot trends on charts, and catch problems before they cost you livestock.

Built for every setup, from a nano reef on a desk to a fish room with a dozen freshwater and saltwater tanks.

WATER PARAMETER TRACKING
- Log pH, ammonia, nitrite, nitrate, temperature, salinity, calcium, alkalinity, magnesium, phosphate, and more
- Color-coded indicators show green, yellow, or red so you see trouble at a glance
- Ammonia and nitrite are held to strict safety thresholds, so a toxic reading always shows red
- Trend charts over weeks, months, or years reveal slow drifts a single test hides
- Overlay maintenance events on charts to see how water changes and dosing affect your parameters
- Set custom ideal ranges for each tank type, whether reef, planted, or brackish

LIVESTOCK MANAGEMENT
- Track every fish, coral, invertebrate, and plant across all your tanks
- Record purchases, quarantine dates, and health observations
- Log losses with cause and date so patterns become visible
- Compatibility checker covering 32 popular freshwater and saltwater species

MAINTENANCE AND DOSING

- Log completed tasks with costs and notes
- Full maintenance history with cost tracking per tank and per month
- Swipe to mark tasks done right from the home screen

## Version history (last 3 releases)

### 1.1.0 — 2026-08-11

The compatibility checker is now where you can actually find it, and it reads correctly.

- The species compatibility checker is reachable from your tank list and from any tank's detail screen. It was previously unreachable.
- Fixed an "Incompatible" result that rendered invisible, so a warning could be missed entirely.
- Fixed five species pairs that could never be matched, so the checker returns a verdict where it previously came up empty.
- Ammonia and nitrite warning thresholds now flag genuinely unsafe readings sooner. Existing tanks are migrated automatically.
- Full dark mode support across every screen.
- Fixed a crash that could occur on launch.
- Species count in the description now reflects the real library.

Thank you for the reports that led to these fixes.

Improved descriptions and keywords to help you find Reef more easily. No changes to app functionality.
