clowder - 1. Is the water still cloudy and appearence of bloom still present?
2. You or the boys (jr. High or +) make your self a visibility tester (secchi disk). Get a white plastic lid abt. 7-8" dia (Kool whip lid okay). Put a hole in the center, put a 4 to 6 ft string or small dia cord thru center and knot end so it won't come out hole. Meassure how deep the disk disappears when lowered into the water.
3. Let's get a lab test / analysis (microscopic)of the pond water. A good Doctor can't do much for a serious elusive problem with confidence w/ out a "blood test". See my Oct 31, 02 post to Pottsy under heading: Balance of Plants in Environment / topic; Temperature Range for Plankton on how to get and preserve some pond water. You got health insurance and do you need a listed provider?; just kidding. All it will cost you is the postage. Any questions before we start treatment?
