Bought a used aquarium (First Salt Water). Completely disassembled everything cleaned it and now down to the bulkhead cleaning. This is a SC Aquarium, so it has a glass lip, making it very difficult to work inside the Weir. Tested the weir for leaks and it leaked as I feared. Watched a few YouTubes to figure out how to remove the bulkhead nuts (yellow arrow) and went to move forward, until I realized there was a Grey piece (red arrow) at the end that looked like it was glued on (Not screwed) preventing me from getting the bottom nut off. As you can see getting the top nut off is not going to be easy x3 given the small space due to the glass lip. Thoughts on how to get this out? Does that grey piece come off somehow and I am missing something? Or did I just discover one reason he was getting rid of it (inability to fix the weir leak easily)? (I will remove the "included" toothbrush once I can get this weir out). Finally, if this is a worst-case scenario, am I better off simply cutting the weir out of the aquarium removing the pipes, cleaning everything, adding the pipes back in then resealing the weir? (Yes I anticipate this is not going to be as easy as it sounds)
