NextUpReef is the reef tank app that keeps your whole system in one place: water chemistry, dosing, equipment, livestock, reminders and AI advice that actually knows your tank. Built for reefers, by a reefer. LOG A FULL TEST IN SECONDS Record alkalinity, calcium, magnesium, nitrate, phosphate, salinity, pH, temperature, ammonia and nitrite. Your last values pre-fill, and every entry is color-coded against your target range as you type. Pick your tank type (mixed reef, SPS, LPS, softie, nano, ULNS and more) for sensible default targets, or set your own. EVERY TREND, TWO SCORES — REEF PULSE See a chart for every parameter with your target range drawn in and water changes marked. Your Reef Score shows how healthy the tank is today; your Stability Score shows how steadily you keep it that way. Tap either score to see exactly what's helping and what's holding it back. REEF AI ADVISOR (PRO) A full analysis of your tank built from your own data: parameters and trends, water changes, livestock, equipment and dosing. See what's working, what needs attention and what to do next, ranked by urgency. Ask Reef AI Chat anything about your reef, check livestock compatibility with the Stocking Advisor, and log results by snapping a photo of your test kit. EVERY DOSE, ONE CHECKLIST The Dosing screen lists everything due today, whether you dose by hand, with your own pump or automatically. Tap Dosed to log it and watch whether alkalinity, calcium and magnesium are holding steady. Choose from 50+ common products with label strengths built in. Pro adds a dose calculator that dials in your daily dose from your own test trend, and a daily dosing reminder at the time you pick.
