Proof of Concept with the use of Lake Guard H2O2™ against Prymnesium sp.

Place: Maagan Michael, Israel

Date: May 2017

A trial against Prymnesium sp. was conducted in Kibbutz Maagan Michael, Israel, in collaboration with the local Fish Health Laboratory. We concluded that two serial treatments of 50-100 ppm of Lake Guard H2O2™ at a time intervals of 3 hours was sufficient to eliminate Prymnesium sp. without significant effect on the other phytoplankton in the water. Although Prymnesium sp. disappeared from the water immediately after the treatment, other water parameters of specific conductivity, pH, temperature and Chlorophyll-a did not alter much during the treatment period. Moreover, fish were found susceptible to these H2O2 concentrations. This methodology is in agreement with work previously done by Profs. Aaron Kaplan at the Hebrew University and Assaf Vardi from the Weizmann Institute, Israel.

Prymnesium sp. was also treated with Lake Guard Blue™, as can be seen in the pictures below, at the concentration of 2 g/m.
