Water intelligence
The tank score is a weighted read of three things: how far each parameter sits from where your livestock needs it, how fast it is moving, and how long it has been out. Tap any score and the full derivation opens, line by line, so you can always see exactly why it said what it said.
A stable 7.4 dKH is a different situation from a 7.4 that was 9.1 last week. The score treats them differently because your corals do.
An SPS-dominant tank is scored harder on alkalinity stability than a softie tank. A fish-only system is judged on what matters to fish, and calcium sits out entirely.
When recent data is too thin to judge something, it says so and tells you what to log. Silence beats a confident guess.
Alkalinity, calcium, magnesium, nitrate, phosphate, salinity, temperature, pH, ammonia, nitrite, potassium, iodine, strontium and more — logged by hand from any test kit, imported from a spreadsheet, pulled from an ICP report, or written automatically by a ReefBot.
Manual entries and device readings land in the same history, on the same charts. Every reading carries equal weight.
Set your own thresholds, or let trend detection catch the slow slides that no threshold would ever fire on. Delivered by email and push, and free on every plan — an alert only works if it reaches you, so it stays out of the paid tiers.
