My camera sucks and I had to shrink down the pic to post it. It is actually 85"x 30"x 30" minus the overflow. That guy has alot of help from people that have had plywood tanks for a whyle. I am following his thread very closely. I broke all my drill bits and havent had time to get anymore. (I work to much). I still have to install the front and the vertical part of the overflow. but I did order the fiberglass 50 pounds shoud cover it (I think). I gave $35.00 for it. I havent decided on the epoxy yet but what I am looking at is about $150.00 for a 3 gal kit. He used the west systems epoxy but those prices are outrageous. The 1/2" tempered glass is about $175.00 for the size I need. So you figure about $450.00 for a 300 gallon tank You could probably go bigger (I had a little bit of plywood left) but I was restricted to what can fit through the door way. I cant even find a tank this large around here, and I know it would cost $1,000+ to order one. Not bad, just a little work. It is fun though. btw I used 3 sheets of plywood.
