I have a 190 going on a stand that I build. So I put my 75 gal sump in and I now have a problem..... I can't fit the skimmer in or take the skimmer cup out. I can not through the other side where I have a door but I have to twist and turn it but that will be built in for equipment....I can modify the other side to put another door in but It will require me to cut out the 2 side supports. Not all the way up but almost.. Will I be safe doing that
