Hi Chad McCann
A picture or diagram would help people on here visualize the setup and someone will have a solution!
Welcome to R2r & Merry Christmas.
+1 on all above; Welcome to R2R! Some pics might allow us to help. For example, I had a 93g cube and a squat 30g sump with a problem of it sticking out of the back about 3 inches. I simply use a 3/4 inch piece of painted plywood extending out so the sump would not overhang and the problem was solved.
I'll bet with all the great folks here we could help figure something out.
Great to have you with us and thank you for joining the family here.
