For overflows, I've always seen an overflow in the main tank and a sump/filter on the bottom. Just curious if anyone has ever pumped up out of the main tank and had the filter drain back into the main tank. It seems quite possible, but I can think of a few reasons why this isn't as great of an idea. I just throught I'd throw this out there for discussion.
