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.
