I was thinking of putting a T into my return line, coming up with 3/4" pvc, and putting a water spicket on it. Then using a short hose connected to a cheap plastic sprinkler, sitting on top of my deck which is level with the top of my pool, to use as an aerator. When the pump is running, I could just open the spicket a bit and turn on the sprinkler, and of course have it pointing back into the pool. I figure this would work for aeration, as well as to help cool the water temp during the summer.
Does this sound like it would work?
