My recommendation is to go easy on the refugium with a new tank. It can take out a lot of nutrients (and traces) in the beginning that you will regret later. I am currently dealing with the fallout from a too-strong refugium on a new tank. Limit light in refugium to 6 hours or less at night, and watch the nutrients. Ideally ICP too, but you might not want to do this.
Oh, and I echo the no-chemical sentiment above. Try not to use any of this stuff. I have heavy cyano right now and would still not chemiclean.
