Pond Boss Forums AERATION Systems questions How Many Aerators do we Need?

In my opinion at a bare minimum you will need 1 diffuser per acre when the system is run 24/7 during water temps above 50F, so in your case I would say four diffusers. Each diffuser could be a dual or triple head unit. If you want to run the system 10-12 hrs per day and get a good water turnover per day, I think 7-9 diffusers would be best and operated by a 3/4hp compressor or two smaller 1/4-1/3hp units. Each single diffuser(1head) based on its size requires a minimum amount of air volume to operate it efficiently, often 1cfm.

Water body shape also plays a big role in how many diffusers are needed. The more round the pond the fewer diffusers that are needed from the minimum.
