My tank seems to be stuck to the ASA. I don't know what happened but for some reason it won't screw out of the unimount. I've tried using a strap wrench on the section connected to the threads and I've tried to take it out the normal way. As I was tryign to take it out, I noticed that the section with the fill nipple and the section with the threads were also moving. There isn't much moving but you can see it shift. Here's a picture:
The pink arrows point to where its moving a little bit. Should I be worried about this? Does anyone have a suggestion how to take the tank off?
