When I built my house twelve years ago, I made a two foot offset between my living room and my dining room. What this has given me is a 8' high x 8' wide x 2' deep offset in my basement. I've always thought about making this a fantastic fish tank. My walls are 8" concrete. This would give me solid concrete sides and back wall. I'm thinking the front viewing area would be anywhere from 6' to 7' wide, after leaving space for feed and return lines for filtration. Height wise would probably be about the same. My question is if I eventually do this tank, what do I seal the concrete with? Epoxy paint. Don't know what else is out there. Really don't want to fiberglass the whole thing and I shouldn't have to because the walls are solid concrete. This is just in the dream stage right now, so just getting some ideas. What do you think. Also give me your stocking ideas. Didn't do any of the math yet, so I don't know how many gallons this area would hold.
