So my used 26 gallon has black sealant (is that what it's called?) on the sides to hold it all together. It looks like it has leaked in the past, since it is sealed in a few spots on the outside.
I filled it up with water, but I'm wondering if I should remove it and just re-seal the whole thing if there's a risk of the seal giving way since it looks fairly tattered. I figure it will be easier now with nothing in the tank than later when it has a whole aquatic community in it.
My dad was thinking to just seal it on the outside (since it's not leaking, so just for extra protection) but I'm not sure if that would actually do any good....
(Yes, I'm kicking myself for not having noticed it before I put in all the water, but oh well...)
These are the front ones... the back ones are not as bad, but I figure if I have to do 2/4, I might as well do 4/4 lol.
