I've bought a second-hand Red Sea XL 200 and for some reason the 'collar' on the return pipe 'through-glass fitting' has been removed (if someone can correct my description of these parts, I'd be grateful!) The removal of the collar has also torn the silicone seal. The 'collar' on the emergency drain is also slightly loose.
As silicone doesn't stick to silicone, I presume I would have to remove the entire fitting and the old silicone from the tank and reseal it?
Any other advice?
