Hey grizz, I planned on building a aluminum pan underneath my sump with a bulkhead with 3" sides so if my sump overflows it will spill into my pan and drain into the bulkhead that will go to a drain into my basement. It will work like a water heater pan. It will also serve as a waste drain where I will do my water changes.
As far as being efficient space for a hob
skimmer I just read that too turbulent water isn't good for your skimmer so I'll probably just go with an in-sump skimmer, and make my return smaller with an ato. Probably go 6" wide, I don't know how deep I should have my water in there tho
