After about 12 hours one side of the paper under the aquarium, the left side, was wet. So I'm assuming it leaks : (
I suppose I should just reseal the whole thing....but how exactly do I go about scraping out the stuff that's there? Should I do anything with the tar sealed in bottom? I don't know where on the left side the leak is...but I'm assuming there's a good chance it's on the bottom...
Also, I read that, due to the difficult of silicon adhering to slate, a separate glass panel can be sealed in over the slate (probably expensive?) or the slate should be cleaned throughly to remove any oily residue and then I should try to make a seal with silicon. As for scraping the tar out...I suppose I'll have to heat it? Would a hair dryer type device work? Can I just get it out with a razor blade and some hard work without heating it?
I guess I'll let it sit for a while longer...see if the seal kicks in with some pressure...but it isn't looking all that good.
