That's too bad about the tank. If I were you, I would contact the manufacturer. You haven't had that tank very long so those seams shouldn't be anywhere near failing yet. I'd let them know you've already purchased another tank(if it's from the same manufacturer) and basically say you want a refund for the orignal tank.
I would advise against the bleach bath. Very few plants have gone into a bleach bath and survived to talk about it. If you search the forum for actual accounts of people who have performed a bleach bath, overwhelmingly people report bad results. A lot of people will say "Sure, perform a bleach bath" but 99% of those people haven't actually done it.
I think that if you do it, you'll lose most of your plants. The only plant that I've read about that can weather a bleach bath is anubias, but, only about 25% of the accounts I've read have had positive results.
Injecting CO2 I wouldn't worry too much about the snails. In my experience, snail shells don't last too long in the low pH environment created by CO2. I've actually *tried* to introduce snails into my tank, and every time the shells melt and all the snails die...and my pH is only 6.5.
Just some thoughts.
