So here we go.

So getting back into the wonderful fish keeping hobby I decided to clean out two tanks. One 10G one 20G. It's been sitting outside for a while... potentially over a year. The hood is bent and mangles but luckily the light fixture was inside all this time

Yeah... it's covered in leaves and everything. I filled it up with water to clean the sand and check the integrity. Everything was up to par. Then...

As you can see on the bottom in the middle water is coming out. It wasn't doing this before. After closer inspection the concrete the aquarium was on was just slightly concave enough to put all the weight on the middle and the silicone failed, then later the corner cracked. Twas sad indeed, but I did not fret cause before that I had already secured another 20G on Craigslist that was supposed to be a long but turned out to be the exact same tank. A blessing in disguise. So what I ended up doing was just cleaning out my 10G and giving it a power filter. I have moved to filter sand as a substrate and I don't think I will ever go back...
