A treatment trial against Prymnesium sp. was conducted in Kibbutz Maagan Michael, Israel, in collaboration with the local Fish Health Laboratory.

We concluded that two consecutive treatments of 50-100 ppm of Lake Guard Oxy™ at time intervals of 3 hours apart was enough to eliminate Prymnesium sp. without adversely impacting other phytoplankton in the water.

While Prymnesium sp. disappeared from the water immediately after treatment, no significant change was detected for other water parameters, incl. specific conductivity, pH, temperature and Chlorophyll-a.

Moreover, fish were found susceptible to said H2O2 concentrations. This methodology is in agreement with work previously done by Prof. Aaron Kaplan at the Hebrew University and Assaf Vardi from the Weizmann Institute, Israel.

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