You prolly already know,but make sure to keep as much old water as you can(if it good water).Make sure all your water parameters in the holding tank are fine before you transfer stuffs over. I've learned a hard way.
i will be keeping most of my water and washing my sand out
ill let the fish and coral stay in the tanks till every thing settles down im hoping the sand will be in the tank with in the next day or to so it will start the cycle
