NextUpReef

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.

CONTROL YOUR REEF GEAR (PRO)
• Neptune Apex: sync temperature, pH, salinity and Trident alkalinity, calcium and magnesium into your logs; switch outlets; run Feed Mode; set heater temperatures; and schedule dosing with a built-in safety shutoff.
• Shelly smart plugs: schedules run on the plug, even with no internet. For dosing pumps, each dose is confirmed by power draw and you're alerted if one is missed.
• CoralVue HYDROS (early access): cloud-connected readings and control from anywhere.

NEVER MISS A WATER CHANGE
Schedule water changes and maintenance like filter socks, carbon and RO/DI filters. Reminders arrive inside the notification hours you choose.

EVERYTHING IN YOUR TANK — MY REEF
Track fish, corals and inverts with care info, plus equipment, lighting schedules, dosing, salt mix, monthly tank photos and what it all cost.

NEW TO REEFING? NEW TANK GUIDE
Follow six guided phases from setup through cycling, the ugly phase, first fish and first corals to an established reef, with a checklist for each step.

LEARN FROM THE BEST TANKS — COMMUNITY
Browse the leaderboard and see inside top-ranked tanks: their parameters, salt, lighting, equipment, dosing and water change habits. Compare your tank with others like it. Your tank stays private unless you choose to share it.
