Stable water grows great coral. ReefDose tells you exactly what to dose, shows how steady your reef really is, and catches drifting parameters before your coral does. No account needed. Your data stays private in your own iCloud. EXACT DOSES IN SECONDS Enter your tank volume, test result and target. ReefDose gives you the exact milliliters to add. • Alkalinity (dKH), calcium and magnesium • Two-part, kalkwasser and all-in-one supplements • Trace elements and custom products • Stock solution mode • Track what's left in each bottle with "runs out in" predictions LOG TESTS FASTER • Snap a photo of your test kit display, checker or handwritten notes and ReefDose reads the numbers for you • Import ICP lab results from a PDF, CSV or screenshot • Import probe and Trident data from Neptune Apex, or a CSV from any controller • Or type results in manually, as always STABILITY SCORE AND REEF HEALTH SCORE In range is not the same as stable.
