no i would just buy a new one, but just to let everyone to know that infant340 is my cousin, so he's fixing it instead of buying a new one because he doesn't have any money
Yes, depending on your finances and the tank size in question sometimes it's not worth it to fix a tank. For anything 40 gallons or larger I would certainly try and salvage it. But if only a 10 gallon, for the peace of mind I'd get not having to second guess my repair work, and for the time saved not having to repair it, I'd probably just get a new one. The cost of a cheap 10 gallon is not that much more than a good sealant if you don't already own some.
