IMHO, I think you would be better off buying a used acrylic tank. Lots of great deals out there on used tanks, whether it's glass or acrylic. I've seen 125's/180's with stands going for $500 to $600...and that's with pumps/heater/ect.
Glasscages.com has lots of tanks, including 180 gallon tanks in various dims. Their 180L is $550 but then there are the shipping costs.
Good luck and post pictures when you have your new tank.
thanks for replies, i have enough for used tank, i bought 125g used last year and it just leaked a few days ago. what a messssss

yes just go to a good lfs and ask for some sealeant. theyll have the stuff you need, as long as its not cracked.you just have to epty the tank and lut the stuff dry proprly. i buy my tanks new to avoid that stuff. get a new 180 and post some pics...
