I wouldn't start dosing anything yet -- and I'd agree with Aquarium Masters' assessment -- 2.5 months is a bit too early for LPS... I'm sure many will disagree here, but I'm a firm believer in a healthy fallow period on new tanks, before stocking them with life... let that live rock become REALLY live!

Good to hear on the refractometer, you won't regret it -- its so much quicker/easier/more accurate, you'll begin to wonder why they even sell the swing arms
