Ted - Pressure is running about 7-8psi

Bill - You were kind enough to e-mail your perch articles to me in March. A quick review of my post: Babbling post should answer some of your query. Diffusers are currently about 15-17ft deep in both ponds. They have been in since Memorial Day.

First DO/temp reading taken via boat this season in the larger pond. The breeze was moving me around a bit so the probe was not real steady but the readings s/b good enough for my purposes:

6/7/06 1:00pm 78F Sunny - I understand time of day will make a diff on DO and will take some in the am/pm as the season progresses......

Depth Temp DO DO SAT
1 75.0 7.30 86.9
3 73.8 7.39 86.2
5 73.2 7.45 87.1
7 72.9 7.69 88.7
9 72.5 7.51 88.0
11 72.3 7.50 86.3
13 72.0 7.33 84.6
15 71.8 7.17 82.3
17 71.4 6.03 68.6
19 71.4 5.29 60.5
21 69.6 6.02 66.0

Not sure how to make the table work but I think it can be deciphered. The 19ft DO reading is suspect.

If I could get away with running the pumps less and the switches will survive that would be great!!

Thanks in advance for further comment/insight....

Chuck
