My pond is 16,000 gal and I have 2 large air pumps. Each pump runs two 10-12 inch Alita airstones. I usually keep 1 airstone in the filter to support the aerobic bacteria. I keep the other three evenly spaced across the pond. My question is...what effect would it have if I put those 3 airstones all at one end. This would be to make viewing the koi better, as the airstones really make the surface ripple. So, I would feed and view them at one end...and my airstones would all be at the other end. Would this affect oxygen levels to any great degree? I don't want to do this and then have any regrets if oxygen levels drop. As always...thanks for the help!!
