I have long felt that the standard cookie cutter approach on starting aerators for more and more time each day is not specific enough for the various conditions that ponds are in. I use my nose to determine how long to run an aerator. Even after four years I still have one diffuser that always smells in the spring. It happens that it is the one that is in the deepest part of the 3 acre pond. I start all five of them, let them run for 15 or 20 minutes. Then I go over each bubble pattern and smell. If they don't smell I leave them on. If one smells I limit it's run time to about 15 minutes. The next day, if it still stinks I still limit it to 15 minutes. I do that until the smell is greatly reduced. Sometimes this takes a week, sometime, like this year, I limited one of the aerators to 15 minutes for over two weeks.

No problems ever with fish piping or dying.
