ReefBay data · Reef tank sizes

What size reef tank do most people have?

This page is being computed. Check back soon.

These numbers come from real tank profiles in the ReefBay app, not from a survey. Every saltwater tank with a volume counts once.

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: every saltwater tank with a display volume between 1 and 5,000 US gallons (about 18,900 liters). Volumes entered in either unit are converted, so every tank counts the same.
  • Sump volume is the user-entered sump volume. Tanks with no sump volume count as no sump.
