Pond Boss Forums POND CONSTRUCTION Selecting a site Surface Aerator

I see on the website of Southeast Pond that all aerators they sell are surface aeration products. Surface aeration has benefits especially is shallower ponds or 7-8ft deep as noted by esshup. Just surface aeration in ponds deeper than 6-7 ft allows buildup of anoxic (bad quality water) in the deep basin and associated sediments. Do your diligent homework. For good decomposition of bottom organic materials you want some bottom uplifting water aeration to mix the deep low quality water to the SURFACE where it naturally gets diluted and reoxygenated. With just fountain aeration the fish in sumner stay in the upper warm oxygenated water zone of 6-7ft deep where there is usually good beneficial oxygen. For best pond management and deep water oxygenation and organics decomposition you want full pond water curculation bottom to top. Well educated pond managers should know these basic facts of pond ecology.

Surface aerator electric motors have relatively short life spans due to their very heavy work load of lifting and throwing heavy water (8lbs/gal) into the air. The frequently need expensive repairs and motor replacements. Bottom aerators pump and mix light weight air so the motors require less horsepower and fewer repairs and longer motor life spans. Ideally it is good to have both types of aerators so when there is an oxygen shortage the fountain can create a higher oxygenated area for more fish to survive the fish kill.
