Buffer welcome to the forum it is a great place to learn. You should post what your D02 levels were just for interest sakes. How old is your pond and how was it made. natural or a gravel pit? I would buy a windmill (I just did actually) There is alot of info on here about winter aeration. I think placing your diffuser in 15-20 feet or so would be ideal. I think the rule of thumb is to place diffuser at 2/3 of the pond depth for winter aeration. Oh yah I want to see some pictures we like pictures!!!!
