While plumbing my new glass tank, I found the water level touches the center brace of the tank (when main return pump is running). I have to lower the water level about 1/2" ~ 3/4" by lengthen the teeth of overlow box. Unfortunately the overflow box is firmly glued in place. Does anyody have any idea of cutting teeth of overflow box while it is already installed? Any recommended tools? Thanks!
