I am trying to use mounting arms to mount 2 Orphek Atlantik V4 GEN2 to my Red Sea Reefer 750 XXL. The problem I am having is the glass is to think for the mount with the shims in it. They give you two thin glass guards and four thick. I can make the mount work if I use two thin guards, but they don’t give you enough to do that. Help anyone use these mounts on a 750? @Orphek
