And I have too much vegetation due to the water clearing. Plankton, like vegetation also effects the DO. One thing I have noticed this year is my water temps are quite a bit cooler, I think it's because of shading due to plants.

I am pretty sure the low visibility is due to both clays and blooms. What kind of blooms, I can not say. The pond is trying to surface scum-up on me right know. The oily looking film that turned into serious scum floaties last year. Here's a pic of the water, the grey bucket is about 4-5" under water. A jar test shows that it clears up well within a week or so...I'm thinking clay and blooms...This photo was taken before the surface scum appearaance.
