I will amend that to lowest open reservoir. In tank overflows should work fine if using a canister filter or other type of sealed or pressured container.
I see what you are saying and have turned off my drip for the time being. Going to get a bulkhead and a diamond hole saw to put the overflow in the sump. The overflow box was fuller this morning, but not enough to drain out. This also is a solid backup should the power go and for some reason the sump was fuller than normal that day, it can exit the system all together. I greatly appreciate you catching this oversight.
