When you buy some sand, make sure it is not play sand from HD. Buy aragonite based sand only!!!!! Otherwise you will be fighting algae! Also, once your tank get up and running, post in the WTB/Trade section here, and we could give you some cups of sand to help seed your new sand. "Live" sand that you buy in the store has usually been there for months, so it's not really live anymore, but the color choices are second to none!
This is a fantastic hobby, and I am extremely glad that you stumbled onto this site. Aprilmayjune told me about MAAST when I bought my first setup, and I adore it! This is a great group here, and everyone is eager to help!
Oh yeah!!!!!!!!! I almost forgot...... Look up wetwebmedia... Bob Fenner is all over that site, and there is also a ton of good info there!
