Aquarium Water Tracker - Reef

Log every water test, track fish and coral, schedule dosing and maintenance. Reef turns your aquarium data into charts that catch problems early.

Stop guessing if your tank is healthy. Reef turns every water test into a clear picture of what your fish, coral, and invertebrates actually need. Log parameters, spot trends on charts, and catch problems before they cost you livestock.

Built for every setup, from a nano reef on a desk to a fish room with a dozen freshwater and saltwater tanks.
