I have brown "dust" thats all over the pool floor and in the corners of my pool. Its not slimy, it can be swept away very easily then settles to the bottom again. Im thinking this cannot possibly be algae as the water is clear and I've maintained my chlorine diligently. I have not had CC in weeks. Could this possibly be pollen? I have many trees in my yard-large oaks/pines and who knows what else. I have a Taylor 2006 kit and these are my results.
