Saltwater Aquarium Log

Saltwater Log tells you what your reef tank is actually doing between water tests. Log alkalinity, calcium, magnesium, nitrate, phosphate, salinity, temperature and pH. See every parameter on one screen, colour-coded against reef target ranges, with the trend at a glance. DOSING THAT WON'T CRASH YOUR TANK Enter your product once from its label — any brand, any country — and Saltwater Log works out exactly how many millilitres you need for your net water volume. If the correction is too big to do at once, it splits the dose across several days automatically, so alkalinity never moves faster than is safe for SPS corals. KNOW YOUR CONSUMPTION This is the number no other app gives you. Saltwater Log compares what you dosed against what your parameters actually did, and tells you how much your tank consumes per day. When that number starts climbing, you know before your levels do. STABILITY SCORE One number for how steady your tank really runs. In reef keeping, stability matters more than hitting a perfect value — this makes it visible. BUILT FOR REEFERS - Litres or US gallons, degrees C or F - Multiple tanks - Test reminders on your schedule - CSV export for your own spreadsheets - No account, no servers - everything stays on your device FREE TO USE One tank, six core parameters (alkalinity, calcium, magnesium, nitrate, phosphate, temperature), 14 days of history and the dosing calculator with one saved product are free, forever - no account, no time limit.
