Newest Method for Directly Controlling Cyanobacteria
-Blue Green Algae-
A recent exciting paper is available on cyanocides (defined as chemical treatments that can be applied to a lake so lightly they directly target & kill cyanobacteria but do not harm beneficial "good" algae). Just one application per year may be all that's needed in some lakes. Two common substances that can be applied lightly as a cyanocide are hydrogen peroxide (which has vitually no residual) and chelated copper in the parts per billion (ppb) range. Medora Corporation is developing a SolarBee® on-board tank and chemical injection system specifically for injection of cyanocides as an added layer of protection against algae toxins in lakes & reservoirs. This system will be an optional add-on for new SolarBee® SB Series equipment and can also be installed on existing machines.

Latest Method for Indirectly Controlling Cyanobacteria by Reducing Nutrient Released from Lake Sediments
Two recent papers are available on how iron could help stop the release of phosphorus from lake sediments. Phosphorus release is not just about anoxia, iron and sulfides play a critical role. Medora Corporations's chemical injection system mentioned above could have an application here.

New EPA Paper for Raw Water
About two-thirds of American drink lake water, and almost half of those lakes now have harmful blue-green algae blooms. There is a new paper by the US EPA on how to set up a Cyanobacteria Management Plan (CMP).

Lake Varner Opflow Article "Tackle Harmful Algal Blooms With Near-Surface Circulation"
A Georgia county is winning the battle with blue-green algae (cyanobacteria) in its raw water reservoir though epilimnetic (top 8 ft) circulation. Circulators paid for themselves in three years, cut the need for chemicals, restored water quality & the natural food chain, and eliminated taste & odor issues for potable water customers.
"SolarBees have completely eliminated our need for Algaecide application in the lake and has lowered our PAC (powdered activated carbon) usage by at least 75%. This has truly been a tangible cost savings. Direct chemical savings from the SolarBees have been over $250,000 this first full year cycle. Customer support and service have been superb. Top notch in that area. These are very well built, well designed, robust pieces of equipment. Our expectations have been met. Yes, I am a fan of SolarBees. They simply work."
