I recently installed a aeration system, ECO7 pump, 3/4 inch pvc running 100 feet to water edge then weighted hose to three 9" diffusers. At 14 ft deep it will not work. Lifting it up a couple feet, works well. I assume this pump does not have enough push. The pond is down about 3-4 feet from full so when it does fill it will be running in 18 ft of water. Any recommendations on a pump for this application. I would really like to keep the diffusers in this location for the summer (close to center of pond and very near the deepest point). Any advice would be welcome. I would like to keep the cost down.
Or would results be the same if I mooved the diffusers into 10 ft of water even though the pond hopefully will fill to 18 ft
soon.
Thank you
