In the end you will probably have to have the DO data to avoid the "it depends" answer for your specific water.


Agreed. It all depends on the O2 demand in the pond, but a week or so shouldn't be too bad. I have seen a winterkill in a pond with medium O2 demand in a span of less than 3 weeks with a windmill system.
