Glad to have you aboard Louis!

Generally new hobbyists do well to using a larger tank as their first since fluctuations can appear so rapidly in smaller tanks. Nano's are great though and a fun challenge. Just take things slowly and don't go overboard and you should enjoy yourself.

You should also check out www.nano-reef.com as there's a whole community based on maintaining smaller sized tanks.

Hope to see you around.

Chris ;)
