Pond Boss Forums AERATION Should I aerate? Winter aeration

I'm beginning to wonder if winter diffusers should be constructed differently than summer diffusers?

The goal in the summer is to move as many GPM to the surface as possible. Fine bubbles accomplish that more effeciently than coarse bubbles.

In the winter, its the wurface disruption and consequent moving water (waves/ripples) that keep the ice open.

Should we be using a coarser bubble diffuser in the winter to make more of a surface distrubance, therefore keeping the open water hole larger?

I have a cheap membrane diffuser in the winter diffuser location. I pump a LOT of air into it, and the diffuesr boil looks like it's 3" or so tall. There is a lot of water movement in the hole, and I've not seen a small open area in my pond this year. Other ponds that I've seen wtih little airflow and fine bubbles, have completely iced over in the coldest weather.
