I am interested what they have to say too, Bocomo!
I am wondering if shallow aeration will work the same way in the winter as it does in the summer. I THINK maybe the warmer water temps in the summer help to keep the water stratified. I am wondering if it will stratify the same way in the winter with water that is near freezing.
Basically I am pretty certain by keeping my diffusers in deep water all winter I am keeping the bottom of my lake awake and active and it is a huge Oxygen suck. My DO levels plummet rapidly when there is no hole open (that is with clear water and very few fish). I am wondering if I can shut down that O2 consumption by rearranging my diffusers, and if I can, how deep do I run them.
