WOW! Good luck on that one. I have a 6' x 3' x 2' that I built myself. Just build a plywood box. Cut a hole in the front and coat the inside with three coats of epoxy. Put in 3/8 inch glass and you are in business. Should take about two weeks in your spare time.Ideal dimensions are 8' x 2' x 2' or 6' x 3' x 2'
Yea, I don't think I'm going to build one myself. Actually at least two or three times a month 240 gallon or larger tanks appear on craigslist. Sometimes at reasonable prices and often not. 8' x 2' x 2' isn't too uncommon but yea, 6' x 3' footprint is tough to find, at least until the marineland tanks have been around for a few years.
If it is that easy then maybe I can afford to hire you to do it
