Nano size and other stuff

[reefburnaby]

Steve,

The definition of a Nano isn't to clear. The way I used to see Nanos was that 20 gallon tank was the minimum size tank for any aquarium. At least, an aquarium that is large enough to be stable and can keep reasonable size fish. However, it is not hard to keep tanks smaller than 20 gallon, it just means less stability and less room for error.

For a while, people had a tough time keep corals in any tank, so tanks with smaller volumes were considered a bad choice. Today, technology and improved knowledge have changed that. It is possible to keep a successful reef (such as a 2.5 gallon) without too much difficulty.

But, keeping a 2.5 gallon reef is much more interesting than keeping a 25 gallon reef. You can still use conventional hardware for 25 gallon, but 2.5 gallon is a lot different. Skimmers, reactors, mega pumps are useless in a 2.5 gallon. However, a weekly 1 gallon water change is all that is needed to keep the 2.5 G happy.
