Per the Weedtrine-D product label: Where algae are present along with the submersed weeds, pre-treatment with CUTRINE-PLUS® Algaecide is advised for optimum results. Since it advises to pre-treat with the Cutrine Plus we would recommend doing it in seperate applications and give sufficient time for the Cutrine to work.
