I'll have another aerator in the deep end in addition to the one in the shallow end. I'll be using the can air 2-ss. It should turn over my water once an hour. I'll have the water from the water falls pulling from pumps in the deep end and then flowing off the waterfall in the shallow, and a pump in the shallow end flowing off the waterfall in the deep end. I'm thinking that will also help "rotate" the water. I have another smaller pump I'll use for the skimmer and that cleaned water will flow down a stream in the shallow end.
