What are your thoughts on this plan: 3/4 acre pond with almost perfect oval shape and max depth of 13 feet. Gast 0523 running 50 ft of 3/4 poly tubing to waters edge then stepping down to 100 feet of 5/8 weighted line to a three diffuser setup in the middle of pond. Three 9” Flexair rubber membrane diffusers. Anything you would add or change?
