I have a fowlr tank, but would like to have a small reef tank as well, now that we know what we are doing. I have read alot about "nano tanks". It seems based on that info that it is possible. Here are my questions:
1. Can I just by my own small (12 or so gallon) tank, not buy the "nano" set up.
2. If I do, what equipment do I need. Being new to reef keeping I don't know the lingo to well, so be basic.
3. What is the purpose of fans on the on the Nano?
4. What exactly can you put in the tank. Can anemones go in? How many different things? I know only 1 or 2 small fish, but what about numbers of inverts, corals etc.
5. Should the substrate be sand? I plan to cycle with sand and live rock.
Thanks so much for your help!
