It sounds like the "Aeration for Dummies" version could be
- Make sure you don't super-heat (controlled by monitoring water temperatures and running at night during hot weather and may need to raise diffusers to keep a bit of a thermocline)
- Make sure you don't super-cool (controlled by monitoring water temperatures and not running diffusers too deep during Winter in order to keep a thermocline)
- Make sure you don't over-saturate (controlled by reducing the flow rates and/or hours run if DO levels rise to observable amounts - or - use a DO meter to measure levels)
Otherwise, run at whatever rate will turnover the pond volume at least 1 time per day.
Am I missing anything?
