are you going to be able to control the water flow in the fuge? try to build the fuge as one unit and the sump as another unit. that way you can control water flow to fuge and full pump flow to sump. water flow to fuge should be slow. i don't know about the home depot pump. they might genarate to much heat. i would go with a mag pump. maybe a 7 or 9
