I picked up a used Red Sea 450 yesterday. The top right side where the sealant is at looks like it could have some air in there. The tank holds water just fine and there is no leaks. Just wondering what you guys think and if anyone has experienced anything similar. I attached two pictures one is left side that looks how I would expect and the other is right side.
