ReefBalance Dose Lab

ReefBalance Dose Lab is a premium, offline-first reef-tank chemistry workshop. It takes the number your test kit just gave you and turns it into an exact, reef-safe dose — no guesswork, no spreadsheets, no network connection required. ONE DRAG ON THE DOSE DIAL Rotate the detent-haptic Dose Dial to set today's target delta. ReefBalance Dose Lab solves the dose from your tank's net water volume, the chosen product's concentration, and a max-safe single-dose cap, then shows the drip rate, the expected swing, and the cost of that correction. Two-part, three-part, kalkwasser, Balling, all-in-one, or your own custom concentration — all handled. THE CA/ALK/MG BALANCE TRIANGLE The balance triangle is a ternary chart you drag your tank point across. It shows which ion to correct first, how far each swing can move the other two, and where the ionic-imbalance warning zone begins. Beginners stop chasing three numbers at once. TANK PROFILES Tank profiles track display litres, live-rock and sand displacement, product line, and per-tank Ca/Alk/Mg target bands for mixed reef, SPS-dominant, softie, or fish-only systems. SALINITY DESK Temperature-corrected specific gravity, hydrometer and refractometer calibration against a 35 ppt reference solution, and a slider that shows exactly how a one-degree temperature shift moves the reading. MIXING STATION Grams-per-litre make-up saltwater for a target salinity, an RO/DI top-off evaporation estimate, and a water-change planner that matches tank temperature and specific gravity. DOSE SCHEDULE SPLITTER Break a correction into morning and evening drips, cap the daily alkalinity swing, and preview the seven-day ramp as a bar chart with reminder times. GUARDRAIL CARDS Enter an out-of-range parameter and a colour-coded caution card explains the reef-safe window and the risk — alkalinity burn, precipitation, or ionic imbalance. PRODUCT LIBRARY Seeded, brand-agnostic product data such as "1 mL raises 100 L by 0.1 dKH" with cost per full dose, plus fully editable custom products. UNIT CONVERTER Live two-way editing: dKH to meq/L to ppm CaCO3, ppm to mg/L, and specific gravity to ppt to refractive index — with your tank's own reading pre-filled. REMINDERS, WIDGET AND EXPORT Dose reminders for each scheduled drip, a home-screen widget showing the millilitres still owed today, and a plain-text dosing sheet you can share or save. WORKS WITHOUT A SIGNAL Every dial, triangle, desk and conversion runs offline, and your tank data stays on your device. Whether you keep a nano reef, run a reef club, work the counter at your local fish store, or simply love aquascaping, ReefBalance Dose Lab gives you the millilitres of the right product for a reef-safe target — every time.
