Anddddd it's almost up. I'm filling it with water now, which is a slow process because my RO/DI unit is tiny. I should take some pics, but it's extremely bare bones at this point. Homemade stand, homemade sump, basic plumbing for overflows and returns. Water flows nicely, I need a few days to fill it so I can mix salt in it. I have to mix salt in the tank because I don't have anything else that large to mix it in without making batch after batch. I'm using a 44g Brute trashcan for RO/DI storage at the moment, which I occasionally pump into the display. I want to be there when I pump it since I've had this tank a long time but never water tested it. So far it's rock solid.
Bought sand and extra salt from AquaPros today. On a scale of 1 to 5 stars, I'd punch the guy who limited me to only 5 so I could get them at least 7 stars. They're rock stars over there, beyond helpful and excellent prices.
It is in-wall, so I've got my little fish room going, still have some supplies to sort out. I need to get my old skimmer back up and make sure it works, going to hurt to find out if it's dead from storage. Need to figure out how I'm going to aquascape this guy too.
Going to start fish only because I don't want to shell out for the lighting right away, but can't wait another year to get a few fish in there.

Also, thank you vpaul1979 if you're still around, I did not use suction cups. We used a giant furniture movers strap that a neighbor has for some reason and seven guys muscled it downstairs gently. I was worried the cheap basement stairs would break with all the guys and 450lbs of glass, so I reinforced them.
