For over sized aerators or ones with too many lifts per 24hr, I tell people to just put the compressor on a timer and run it fewer hours per day. Generally two lifts per day is enough to keep the pond bottom oxygenated. Exceptions are with ponds with high biochemical oxygen demand they need more circulations - lifts per day.
