Well I got started on it last night, went to Lowes, they didnt have black at all, it was special order only. So I went with a creme color, I forget the name but I'll post pics later. Had them cut the tile to what I needed. Came home, drained the tank, moved the fish, etc. This tank used to have I guess a sump or whatever installed below it and 2 5" round holes cut on the bottom of the tank. The owner then used a 2" think piece of acrylic and covered it up from the inside. I initially thought he just used sylicone and was just going to pop the blocks off and patch it. But he did use acrylic solvent. So, I wasnt able to lay the tile down flush. I got three whole pieces in at 12x12. The rest I has to take measurements again and today after work I'm going back to Lowes to have them cut the tile again. I fixed the small leak in the process. I started at 10pm last night and was done by 3am. Was a long night. So today, hopefully all I have to do is lay the tile down and be done with it. I rearranged the filter out/returns hoses and heaters and koralinas to look more presentable as well. Only thing I have to add to the tank is something a little heavy to hold down the tile which will sit on top of the 2 blocks inside the tanks, prolly use texas holey rock unless someone can recommend something that cures underwater to at least hold the tile down from the fish moving it. Hopefully I will be posting photos tonight. All the fish made it, was really worried about the Tig, I seem to have bad luck with them but so far this 18"er is a tough one.
