Pond Boss Forums AERATION Systems questions Winter survival DO vs Hydrogen Sulfide, etc

jpsdad - I have only measured DO in the plume during the summers. Never in the winter for obvious reasons. In the winters we never even get close to the plume - just too nervous.

In the summers measuring directly in the plume usually produces a lower DO number. I assumed because it is bringing up the low DO water from the bottom.

It does make sense to me that the plume could have a higher DO content in the winter though.

Gases like H2S are the other component IMO. I just have no way to measure them and truly know their impact.
