Any sugestions/links would be helpfull
Thanks!

Why would a tank flood when a pump goes out? In general, the sump fills when the pumps goes out.
An inside overflow box 1. breaks open and skims the surface, and 2, prevents the water level from doing down below the opening of the overflow box. I think it is necessary.
How else would you skim the surface. Even a siphon setup is still an overflow box.
