Certain species of algae will attach to sand grains (epipsammic), however there are no published records that I know of for algae attaching to clay particles. Most coloidal clay particles are smaller than most algae cells, thus it would be difficult for the algal cell to adhere to a particle smaller than themselves. I highly doubt that the yellowish color is due to any type of zooplankton. I'm not sure how bleach will differenciate between suspended clays/sediment and living organisms.
