Ya Bill that's kinda what I was thinking as well, I think I'm just going to use some of the sand out of the 90 g. I'm using about 50 lbs of live rock from my 90 g and put the sand in last all around the rocks approx. 1/2- 1" deep I'll just do a bit of a rinse with some old tank water before it goes in. I'm hoping to give the new tank a few days and then transfer the livestock. thoughts anyone.
