Pond Boss Forums AQUATIC VEGETATION Identifying plants red color algee?

Since your pond is due for renovation and drying out of the bottom then I don't think it is necessary to use a chemical to kill this algae. I likely developed due to the water chemistry conditions created by theh concentrated water levels and nutrient conditions. Red algae problem should not return in the conditons of a redug and refilled pond. Nutrient concentrations and water conditions were responsible the growth of the red growth.
