well as of tonight i have been given a 55 gal tank. It is in good shape and leak proof. Right now i have a mature 30 gal tank that has been running for 7 months. I plan on using everything from my 30 in the new tank. I have 27 pounds of LR and 40 lbs of live sand. I do want to add more live rock and sand of course and that is my question. Should i buy the rock and sand now and put it in another tank (i have spare 10 gal) and let it cycle in there or can i mix everything together in the new 55 gal. My livestock right now is 1 true clown 1 yellow tail damsel 2 turbo's and 3 a. snails. Im looking for any suggestions..Thanks
