Recent cases of Blue-green algae outbreaks are on the increase as the average temperature rises and rainfall and phosphorous runoff increases, creating the perfect environment for blue-green algae or cyanobacteria to grow. Even in mid-October 2017, across the Finger Lakes and into Vermont, the algae are blooming, causing a biohazard problem for all areas affected. It has impacted the Great Lakes and many other northeastern water bodies not generally affected by the problem.
Phosphorus can come from several different sources in the environment, including agricultural runoff, septic systems, road runoff, and lawn runoff. Reducing phosphorous pollution requires coordination and management practice changes from many different sectors. It will take some time to see effects of any changes as well because phosphorous that has already reached a lake can nourish algae blooms for years.
Recent Increase of Blue Green Algae Bloom
What makes the fall of 2017 such a perfect storm for algae blooms? First, the lake water stratified, and the water at the bottom became depleted of oxygen. With the oxygen gone, the sediment at the bottom of the lake releases phosphorous. These bottom waters eventually “turn over” and end up near the surface – as food for algae. The excessive spring rainfall pushed more runoff into the lakes, and the warm fall weather has helped the algae to bloom more aggressively than usual. This is a problem because drinking water in the northeastern states of Michigan, New York, Pennsylvania, Vermont and others have been affected by small amounts of toxic algae. This prompted the Senate, on September 26, to pass a bipartisan bill authorizing $22 million a year for five years ($110 million total) to fund research and prevention of blue-green algae blooms on lakes and other sources of drinking water across the United States.
Cyanobacteria or toxic blue-green algae has been documented in 60 bodies of water in New York state this year. In Lake Erie, National Geographic reported that there were more than 700 square miles of toxic blue-green algae blooms on Oct 3. On September 18 the US government posted a press release stating that “scientists surveyed 1,161 U.S. lakes and found that cyanobacteria were the dominant algae in 76 percent of the surveyed locations. Furthermore, 32 percent of lakes contained toxins produced by cyanobacteria.”
Natural Blue Green Algae Control
The most essential step in controlling blue-green algae control in lakes and reservoirs, is to adequately oxygenate the bottom through CLEAN-FLO’s unique lake and reservoir destratification / aeration systems and bioaugmentation program. A CLEAN-FLO reservoir or lake aerator can bind up to three times as much phosphorus and nitrogen to the bottom muck as watershed management can accomplish. This results in up to 97 percent or more phosphorus and nitrogen removal. The phosphorus and nitrogen then become food for insects and fish, resulting in improved lake fishing and pond fishing. Because the phosphorus and nitrogen go into food for fish, the aeration system produces reservoir, lake and pond restoration and algae control.
Once you attain full oxygenation of the bottom of your lake, pond or reservoir with a Clean-Flo destratification / aeration system, the following natural water treatment products will help result in optimum blue-green algae and planktonic algae control.

Installing one of our inversion oxygenation systems along with the products below is the best way to naturally control algae.
Bio Booster– Bio Booster is designed to increase diatom populations and reduce nutrients needed by algae.
CFLO+ are specially formulated slow release disks consisting of beneficial microbes with natural plant enzymes which feed on organic sediment (muck) at the bottom of all water bodies.
Clean & ClearTM -CONCENTRATED ENZYMES is a special blend of non-toxic vegetable enzymes from nature that acts as a catalyst to biodegrade non-living organic matter and reduces available nutrients in the water, thus improving water quality.
Winter Warrior– Increases biological efficiency during colder months to improve water quality and organic muck reduction all winter long.
