Air pockets in Silicone joints?
I noticed while doing a water change today that on two joints there are a series of what look to be air pockets or bubbles forming in the silicone. I have never noticed these before and I think they are new. Not sure how old the tank is as it was purchased used.
Is this a sign of impending failure? Anyone else have anything similar?
