About ReefCMD: Reef Tank Management
ReefCMD is the modern way to manage your reef tank — water parameters, dosing, livestock, and controller data in one fast, clean app built for saltwater aquarium keepers. Stop juggling spreadsheets, notebooks, and clunky web or controller apps. Integrate your Apex (or log a test in seconds), watch your trends, and catch problems before your corals do. WHAT YOU CAN DO • Track every water parameter — alkalinity, calcium, magnesium, salinity, pH, nitrate, phosphate, temperature, and ORP — with clear trend charts over time. • Log dosing, water changes, and maintenance so nothing slips through the cracks. • Get a reef tank Health Score that turns your numbers into a single, at-a-glance read on tank stability. • Browse a deep animal library of fish, coral, and invertebrates — plus a pest guide — to plan your stocking list and wish list. • Apex now and built controller-neutral, with more devices on the way. BUILT FOR REEFERS Whether you run a nano reef or a mixed-reef SPS display, ReefCMD keeps your reef tank on track. Fast logging, honest charts, and the water parameters that actually matter — alkalinity, calcium, magnesium, and salinity — front and center. PRICING ReefCMD is free to try. A paid subscription unlocks the full app: unlimited logging, full history, the Health Score, the Bridge, and the complete animal library. Subscriptions renew automatically; cancel anytime in your account settings. Stay humble — the ocean always wins. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Questions?
