I was looking at maybe getting a Kessil Ap9x for my 40 gallon breeder in the future. I would rather not hang it from my ceiling if I could help it, so I was thinking about getting the mounting arm and attaching it to my aquarium. The only problem is that my tank has the black rim around the edge, so I’m not sure it will fit out of the box. That being said, will it hurt the integrity of the tank if I trim a small section of the black rim at the top where I would want to mount the lighting arm if that’s what it takes to make it work?
