I found out a long time ago that waiting for a long time is the only safe way to start a reef tank. By that I mean six months before adding any livestock. I have also found that people will not listen, and suffer the consequences. The additives on the market to speed the cycle are just crap. The addition of an anemone to a young tank like that is usually a recipe for disaster. Most people would say to wait at least a year before attempting to add an anemone.
I have gone through it all, and lost a lot of expensive fish before I learned my lesson. :bang1:
