Cyanobacteria & Cyanotoxin Mitigation For Recreational Lakes

When in doubt, stay out!

Harmful algae warning signNothing ruins a lake experience more than a blue-green algae bloom. 

The threats posed by cyanobacteria blooms and their associated toxins are real and should not be taken lightly.  There are a lot of opinions one way and the other, but they all boil down to...


What can we really do to combat blue-green algae blooms?

At the heart of any water quality strategy is circulation, and more specifically, epilimnetic circulation.  It is the one consistently successful method that can stand alone or in conjunction with other water quality management strategies.

Epilimnetic circulation diagramCyanobacteria (blue-green algae) usually require warm waters, high nutrient availability (primarily soluble inorganic phosphorus and nitrogen), sunlight, and stagnant waters. Efforts to control cyanobacteria blooms through nutrient limitation have been spotty at best, in part because of the difficulty of controlling non-point sources such as agricultural and stormwater runoff, as well as the impacts of rapid urban development.

The most dependable & effective approach for cyanobacteria bloom control has been epilimnetic circulation with SolarBee® equipment.

The combination of horizontal and vertical mixing sufficiently disrupts the cyanobacteria’s preferred quiescent habitat, negating their competitive advantage over beneficial algae and preventing unwanted blooms, even in nutrient-rich waters such as secondary wastewater effluent and storm water drainage. These benefits of enhanced circulation have been well documented in the scientific literature for many decades.
