Shorty, my deepest water is only 11 1/2 foot at full pool. That's where all 3 aeriators are located. If pond gets 3 foot low like it has many times that would put my diffusers only 2 1'2-3 foot below the surface. Would that still supply oxygen to the bottom of the pond? I have thought about raising them but I had those concerns. Also my visibility has gotton to 32 inch on a secchi dish! I am actually watching my cnbg on their beds right now fighting off predators and...I am seeing schools of 6-8 lmb that are ONLY about 4-5 inch long that I didn't even know I had! I'm enjoying my pond again by being able to see into the water! Reckon I should run the aeriator for 10-15 minutes about once a month just for maintenance purposes??
