Well, just Threw 2 frozen Raw Shrimp in the tank to get the cycle started I think I will take a piece or 2 of the live rock from my QT tank and put that in the 75g also to get it going. Then maybe this next weekend I will order the 25# of live rock to put in the tank in hopes that in 4 weeks the tank will be cycled and I can put my 2 clowns in there..
