I just finished draining a 55Gal. as I am going to re-purpose the tank.
I noticed as I was cleaning it / emptying the tank that a small piece of silicone easily lifted and I managed to make a small 1" tear as it's "flappy" in the one corner.
The tank has been filled with water for about 6 years and it has been re-purposed about 3 times now. This will be number 4.
Does anyone really think this is anything to be worried about?
What's a good way to test the silicon without poking it with various sharp objects?
