I am on the conservative side. I would let it run for another week, checking params and then if it looks good, add slowly. I would disagree with Casingbill on this on. But, like I said, I try not to take any chances. Especially the ones that could cost me $$.
I didn't add any coral to mine for 6-8 months. I don't think I would add any till the tank matures just a bit. Maybe couple of months. Remember patience!!
