Results of this study showed that the highest concentration of the population of heterotrophic bacteria was on pond 4b (aerated pond 2), algae population was highest at pond 5a (sedimentation pond 1), and the population of protozoa was highest on pond 5b (sedimentation pond 2). The population of heterotrophic bacteria was replaced by algae and then algae was taken over by protozoa.
