So here's what I have so far for the live rock. I taped out an area on a box that is just about 1/4-3/4 of an inch too thin on the sides just because I'd rather have more room on the sides of the scape than not enough. Also the line at the top of the back of the box is the height of the tank so I'm concerned that it's a little too small in regards to height so I might pick up another pound or five at the LFS when I go to get glue tonight
