Translucent polyethylene film tubes isolated columns of lake water in which to study fertilization requirements in situ. Production estimates based on gross photosynthesis, chlorophyll‐a, and zooplankton measurements indicated that the tubes performed well. Other measurements including temperature and oxygen stratification and photic depth determinations showed that the tubes did not measurably alter the physical characteristics of the columns of water. Gross photosynthesis and chlorophyll based production estimates reflected similar responses of productivity to treatment. The response of zooplankton to treatment was not as clear.
