It's only forever; not long at all...
Or just use it for something non aquatic...
I'm sorry, but i disagree with y'all, I had the same situation (granted it was a 5 gal hex, so a little more money) the tank ahad a small crack, and the size doesn't create too much pressure, so i thought i would try to use crazy glue, it worked, i used it inside and outside on the crack and it got right inside the crack to seal it up, and since then I have set that tank up and the seal is fine. So if you've got the time try it out, if it works you have a free tank, if not you haven't lost anything other than a few drops of glue.
i have a 2 foot tank which i'm gonna use and it has a big crack across the bottom of it! i'm gonna cut the whole payne out, just slide a stanley knife along the silicone seal, and silicone on a piece of plexi glass, the same stuff people use for making dividers it only costs pence and is a lot easier to cut to shape than glass!
I have a question for you guys: I have a 20 gallon long in our garage and it has a crack about this big in it:
--------------------------------------------------------- How would i fix that? Just buy a glass pane? Use silicon sealant? Dont bother?
The crack is on the back of the tank and it runs to the joint on the bottom.
