Well I didn't what this to happen, but it did. I started three different topics and all of them are talking about the something. I just didn't want to have one topic that was talking about three different things at once.
I'm buying a Minn Kota Water Temp Sensor through Cabela's like Bill Cody suggested instead of a DO meter. I'm going to measure on the bottom and top of my pond and look for no more then a 5F degrees difference when my aerator shuts off.
I can't hear my compressor more then 7' away, but mine sets under my front porch which is 75' from the pond.

Cecil,
You have noticed that aerating 24/7 helps the bloom. What's everybody else's findings?
