you could put a Y connector and have a control at the end of the y connector. Have 1 end going back to the main tank and the other going back into the sump.

dosent that kinda defeat the purpose of more flow?

Your Overflow box can only drain so fast. If the pump are too strong and you do not try to divert water back into the sump then it will foce all the water from the sump into the main tank.
2 thing will happen. water will be on your floor and the pump will die because of running dry.

another u tube to the drain box on back wouldn't work?

I do not think another U tube will work, since your drain hole on the overflow can only drain so much.

Give it a try if you have an extra u tube.

Drill another hole in the over flow like you see in my house with a new U tube will give you too much flow going down, and since there isn't enough flow in each U tube, you will begin to miss siphons. What i suggest is get a 1/4-3/8 hose and just put that in the over flow box located in the tank, and route it into your sump, this way you will not drain out your own tank if power went out, and you get more flow without having to drill anything.
