I have a thread all about my 55g reef called "update of Beengirl's 55g reef" under "members saltwater tanks"-lots of pics and all my equipment is listed on my profile page. To cycle, I used a raw shrimp. I have 80# live sand, started with about 40# LR
, have added some since then and have a little over 60# now, but you can have as much or as little rock as you want. If you want fake decorations, the BB will grow on that. Make the tank look however you like. The BB will find a place to grow- the sand, decorations, filter, any rock you might put in there, etc. Let me know if you have any questions!
