Bill,
The pond alkalinity has been 60 to 80 and ph varies around 8.o. I do occasionally have ph approaching 8.5 to 9.o in the summer. I have extended vegetation buffers from agricultural operation to over 200'.
I do have some turbity after heavy rains but plankton bloom maintains from run off. I have not fertilized and have never had visibility over 24".
Thanks for you input.
Al
