I took another reading in the pond and in the stream this evening. The water temp in the pond is 63 deg.F. I did not check the stream temp though. The readings after a day of sunshine were 8.9 ppm in the pond, and 6.6 ppm in the stream. That is up from 7.5 in the pond the other day. I'm assuming all the sunny weather had something to do with the increase?

I'd like to get out there on a dull day or early in the am and see what reading I get.
