a nano reef is a type of marine aquarium that is typically less than 140 litres (30 imperial gallons / 37 us gallons). the exact limit that distinguishes a nano reef from a regular reef is somewhat ill-defined. some claim that anything less than 180 litres (40 imperial gallons / 48 us gallons) would qualify. but 140 litres (30 imperial gallons / 37 us gallons) seems to be the generally accepted limit. nano reefs have become quite popular in recent years among fish keeping hobbyists, primarily because of their smaller size, maintainability, and the possibility of lower costs. the burgeoning interest in this niche of marine aquarium science has fostered several notable contributions ranging from specific consumer products such as specialized aquarium filters, compact high intensity lighting systems and smaller circulation pumps. such equipment allows the aquarist to maintain an environment wherein many marine organisms are capable of thriving.
