The data below describes the numbers of phytoplankton in both the ambient challenge
water and the post Hydac filter water during all test trials. Size-class distinctions or measures are
determined by considering the greatest available measure among the x, y, and z axis. Total
phytoplankton numbers are broken into two size classes.
