Pond Boss Forums AERATION Should I aerate? New 1/4 acre pond - need aeration

A 1/4hp dual voltage rotary compressor (GAST mfg) would be very adequate for your needs. I don't think the rocking piston compressors are dual voltage. Compressor airflows or 3-4.5cfm will allow rapid turnover of your water volume. Thus you likely will not need to run the unit 24/7; maybe 4-8hrs per day with proper efficient diffuser. Compressors DO NEED to be in a WELL ventilated, weather proof shelter. There are several diffuser styles that would be quite good for your pond configuration.

I usually do not get too concerned about adding aeration until the pond is full and is relatively clear (visibility 2- 4ft and 8 to 16 months old). Aeration can prolong settling of fine coloidal clay particles. You want your airlines and diffuser NOT permanently affixed to the bottom so they can be easily moved/removed and or cleaned when necessary. Your pond size will allow for convenient installation of diffuser if it has a slider, rounded base, and a rope attached and just pull it into place with the rope from shore. Tie off rope to stake on shore (add a little weight to rope if necessary to sink it). Diffuser can then be easily moved when necessary.
