I would agree with TheBigEasy, I would take 30% of water out for sure so the pressure isn't so strong within the glass. If you have a LFS instead of PetSmart, they might house your fish untill you can get your new tank.

Dont settle for not exchanging it. They WILL exchange it, even if they dont want to, they always will. You need to show up in person though, and be very insistent on them replacing it ASAP since your fish are under a lot of stress. It might also help to threaten to cal Corporate. Store managers want to avoid that. But do not settle without getting it replaced. And in the future, you might want to give craigslist a try when looking at large tanks. I just picked up a 130gal for $50*shrugs* I dunno....
I think the manager he was talking to gave him their name. He was trying to call her last night when we got back home, but nada. Hoping he can get in touch with her today to see about the whole 60day thing.
If we end up not being able to exchange it...... sigh......there goes $400 for another tank.
the 130gal for $50 was a rare one. He wanted $200 but i didnt have it, so i offered him $50, he emailed me a month later and asked if i still wanted it. lol, living in the Detroit area, things are rough and people just cant afford to spend a lot, which means there are some great deals here. I guess it depends on your area.Yeah I look at craigslist every once in a while. Some... OK deals, but nothing as good as that.
