My 2 cents:
•DO NOT use any chemicals or bottled bacteria colonies to "jump start" your tank...
•Don't put any species of damsel into your tank, unless you want it to be there till the day it dies, or the day you remove every scrap of live rock and chase it with a net for two hours.... they will become very territorial and attack anything else you place in your tank.
Cycleing your tank takes time, don't rush it or you will regret it later...
Lastly, do LOTS of reasearch before buying anything, books, this forum etc.
(PS- The Local Fish Stores are notorious for faulty advice no matter how nice and well intentioned they are)
ask all the really experienced hobbiests on this site for the real scoop...
Good Luck!
