Pond Boss Forums AERATION Systems questions Aeration for a 7' deep 1/2 acre pond

I think you can try the above ground airline to see if it will work in your application. Be aware the condensate collecting in hose valleys/dips could freeze enough to block the air flow and this will occur during winter aeration when aeration is needed most to prevent fish kill. Also be aware condensate could drain downhill back into the compressor and damage it ruin the pump. Try to prevent both potential problems. If the above ground application causes problems then bury the airline 3"-6" deep. Try to get all piping to travel down hill or install a water trap in front of the compressor.

Bottom aerating 1/2 acre can be done basically two ways: a. with low air flow/volume (small pump 1-2cfm + one small diffuser) and run continuously or use more air flow/volume (bigger pump larger diffuser)and then mix it stronger for a shorter period of time (several hrs daily). You are in a cooler climate so IMO continual mixing is not necessary. One to two mixes a day is enough for your location and application to maintain oxygenated water on top of all the bottom sediments.
