Thanks for response, Ewest most of your questions are answered in my first post "First Bloom". I did not lose any water over the spillway,only thru the overflow pipe, and we had several rains that lasted a couple of hours each not sure of amount, due to working out of town. Visibility was at about 11" before the last rain. The algea that remains looks like a thin green rug matted together in the upper cove of the pond.( before that last rain boy I had a mess, there were some blue blooms or something looked like paint in areas and one area was like a red dust on the water. The last rain either sank this mess or wasked it out, glad it's gone tho).
Dave, I can see plankton suspended in the water, not suspended clay or stuff in the water, but it has turned brown and the green bloom has not returned, that is the main reason I was asking about what to do if anything at this time. Thanks guys for your time and comments, I will be watching for your responses.
