I always cycle with "Cured" live rock. It has enough die off from the shipping process usually to get a good cycle going. The first and last time I cycled with uncured, it smelled so bad that I just can't do that again. I do a three step cycle over about 3 months though, but thats just a quirkly personal supersition thing I have going.
Here's to swimmin with bowlegged women.
Reef with 30G Sump/Fuge Combo
-30G LTAnemonarium with mated porcelain crabs, 10 sexy shrimp, and 2 pink skunks all tied into the other 135G in my system.
