I made this using a chrildrens plastic pool and a 1/6 hp sub. sump pump. Its working great for curing my LR and sure beats the trashcan method. The pump will work in as little as 1/4 inch of water. It pumps out the top of the unit into the PVC pipes to the outer edges of the pool. About 25GPM flow. Plenty for curing LR. I have it sitting in a trailer so I can siphon easily.
