I moved my 125g 3 times without losing anything. I removed all the CC and LR, left the fish in the tank and moved it last, so that the fish had minimal time to get stressed out. Put the tank on a furniture dolley threw it in the truck, and it was the first thing set back up in the new house. Haven't lost anything yet due to moving. You have to make sure you have the spot picked out and your water all ready to go, so that you can get the tank into place and put it back together quickly. If inclined, get a couple of 30 trash cans and dump some of your tank water in there, so that you can use it to fill the tank with that water instead of using all new water.
