Microbes placed in #10 lake doing their job

The microbes that we placed in 10 lake in June are finally doing their work.  We have not sprayed the lake with any algaecide product in at least 3 weeks even though it has been extremely hot.  The algae that is usually seen floating in a 3-5' ring around the edges of the lake is now being controlled by the little bugs that are chewing up the organic matter on the floor of the lake.  Without any source of food, the algae will not form.
