Hi, I'm not sure if I'm being overly cautious, but I really don't want a tank leak. I'm setting up a 10 gallon. It was manufactured in 2008; I bought it in 2009, and it was sitting empty for one year. I'm wondering when/if a tank should be resealed? See pic: Image - TinyPic
All the seams are fine except for this part- might be hard to see in the picture but some of the silicone has pealed back a bit. The rest of the tank is perfect. Do you think it's safe as is?
