then the fun began, finding a neighbor that wanted to help with the big heavy lifting. Got everything in, reinstalled the drain piping, didn't fit through the door. Got it all set and leveled and even. Found out that the sand i was going to use wasn't going to work, so i haqd to wash out all of the old sand thoroughly, then put it in the tank and starting pumping in water whilst starting to arrange the rock structures. Tried to set it up as 2 islands with lots of open areas. Its amazing how lots of rock in a 55 along with a bunch of dry rock looks very tiny in a 120.
