Keeping a reef tank beautiful and healthy doesn’t have to be complicated.

With PARAreef, you can: Log Your Testing Results: Quickly enter your water test values for pH, temperature, alkalinity, calcium, magnesium, nitrate, phosphate, and salinity. View Historical Trends: Review your last 30 saved readings, with quick insights to see what’s stable and what needs attention. Know When It’s Off: The app highlights if a parameter is too high or too low and gives practical suggestions on how to correct it. Maintenance Checklist: Stay on top of reef-keeping basics like cleaning pumps, changing filter media, checking supplements, and water changes. Tasks reset every 7 days for good housekeeping. Multiple Tank Profiles: Own more than one tank? PARAreef lets you create separate profiles and manage each system with ease. Designed for reef hobbyists of all levels, PARAreef avoids clutter and over-complication. Many aquarium apps are overwhelming — PARAreef is built to keep things simple, accurate, and effective.
