ReefBay data · Real reef tank water parameters
What are normal water parameters in a real reef tank?
This page is being computed. Check back soon.
Most parameter guides repeat textbook targets. This page shows what reef tanks actually run, from readings logged in the ReefBay app. Each tank counts once per parameter, using its latest reading in the last 12 months.
Method
- Source: tank profiles and logs created by ReefBay app users. ReefBay is a reef aquarium app for iOS and Android.
- Excluded: deleted tanks, deleted accounts, ReefBay staff and test accounts.
- Counted: the latest reading per tank and parameter in the last 365 days, so frequent loggers do not dominate.
- Normalized: specific gravity is converted to ppt (1.026 SG = 35 ppt), all temperatures to one scale (shown in °F), ppb phosphate to ppm, meq/L alkalinity to dKH.
- Dropped: readings outside a plausible range for the parameter (for example alkalinity below 4 or above 16 dKH). These are almost always unit or typing errors. The dropped count is shown per parameter.
- Percentiles use the nearest-rank method. "Typical range" is the 25th to 75th percentile.
