Fifteen species of protozoa were used for a 36 day period to test the pH of four protozoa media. During this experiment the pH was determined every three days for control media, the media with bacteria, and the media with bacteria and protozoa. The pH curve included a lag phase, an acceleration phase, a plateau, and a decline with three of the four media during the 36 days. The fourth medium did not have a decline from the plateau during the 36 days. The protozoa and the four media are described.
