Haven't touched the tank yet, but about to go lower the water level.
The crack hasn't gotten any worse thankfull.
Even if I wanted to, can't put anything over the entire crack.
The bottom of the tank has a big black plastic around it, so you can't actually get to the bottom and it appears the crack goes all the way to the bottom or at least behind the black plastic.
I think we bought it with the crack. We did notice a small something there about a week after we bought it, but never even occured to us that it was a crack or something that would develop in to a crack.
I just really hope we will be able to get an exchange quickly.
I guess on a slightly positive.... I get to rescape the tank
It'll probably still look pretty sucky, but oh well heh. Plus I get to clean off all the little black algae that's popping up and bugging the turd out of me.
