I thought about it all night, made a plan, made a few alternative plans, rearranged all the furniture in the living room, and made a deal with the devil. I promised the wife to remodel the kitchen, before building the tank. The next morning I bought the tank. A few days later it came home, destined to sit in the back yard for a bit, until I finished the kitchen.
About a week into the kitchen remodel, a friend decided to break down his 90G, I found myself in a place to get a hippo for $20. I couldn't pass it up, the wife agreed. So the tank came to the front burner. I put the hippo in the 29 for the time being. The next day drilled the bottom, set up the plumbing inside the tank, and built the overflow box.
Fortunately, I had procured items during the week of the kitchen remodel. I set the base rock with epoxy, then moved the live rock from the 29 to seed the base rock. Added the used sand from another tank, obviously cleaned thoroughly. Then added saltwater. I filled the tank improperly according to most. but by pumping the water in via hose onto the rock, I had minimal sand movement.
