Thanks Bill. I talked with some folks at the Jones Fish booth at the Cleveland Home show on Friday. They said I had less to worry about with a new pond but did not make the connection to the decaying organic matter.

My ice appears cloudy to me. I don't know the thickness - did you check your thickness? Our weather must be close to the same so perhaps my ice thickness would be similar to yours. Or Cecil's _ Cecil did you measure ice thickness?

Any thoughts on amount of "dark time" it takes to be a threat to the oxygen users below the ice?

2/3 acre pond 12 miles from that big pond we call Lake Erie.
