This versatility is what makes Euglena difficult to treat. For pond owners who are hesitant to use harsh chemicals, we suggest the use of pond dyes to help prevent photosynthesis, which slows growth. However, when pond dye is introduced to a pond with Euglena it simply switches from plant mode where it is using light for a food source to animal mode. In animal mode Euglena begins eating other organisms in the pond, like green algae. Even if a pond owner would be willing to use an algaecide, the unique structure of this super organism makes it resistant to algaecides too.
The key to control is to hit Euglena while it is at its weakest combined with reducing nutrient levels in the pond. Treating Euglena while it is green with heavy doses of pond algaecide is the first step. The next step is to change the environment. Euglena thrives in a nutrient rich environment, therefore, it is important to use high doses of concentrated bacteria, Muck Doctor, to reduce deep muck deposits. You will also want to use regular doses of maintenance bacteria, Natural Pond Cleaner on a monthly basis.
