New system uses environmentally-friendly ultrasonic waves
to inhibit the growth and spread of algae

TUCSON, Ariz. (February 6, 2013) –-Golf courses that feature ponds and lakes are often more challenging and visually appealing. However, bodies of water are commonly invaded by algae, which is both unsightly and difficult to eradicate. Now, superintendents and golf course managers have a simple and environmentally-friendly way to both kill and prevent algae—Rain Bird’s new Algae Control System (ACS).

“Our new ACS is able to inhibit and control the growth and spread of algae without the use of potentially harmful chemicals,” said Carolyn Maloney, product manager for Rain Bird’s Golf Division. “As a result, it’s safe for use with aquatic life like fish, frogs, turtles and all types of aquatic plants.”

When submerged just beneath the surface of ponds or lakes at least two feet deep, an ACS transducer emits directional ultrasonic waves that fan out at 180˚ to inhibit the growth and spread of algae. The waves hit the harmonic frequencies of various types of algae, eventually causing algae cells to weaken and starve to death. Users can expect results in as few as three to four weeks.

“Because the transducer is a ‘line-of-sight’ device, the ultrasonic waves will not go around corners or navigate around islands,” Maloney explains. “As a result, it’s important to position the transducer close to the edge of the water to minimize the area behind the unit that the ultrasonic waves cannot reach.” 

The ACS is available in five different models of varying power levels. Selecting the appropriate model for a particular pond or lake depends upon four factors: surface area of the water in acres; amount of nutrients in the water (including those coming from external sources); the shape of the pond or lake; and the location of the body of water relative to the equator. In addition to a 24-volt AC model, the ACS also comes in 24-volt DC and 24-volt DC solar models for those sites without access to electricity.

“Large installations and bodies of water in certain shapes may require the use of more than one ACS transducer,” Maloney says. “Fortunately, because it requires the same amount of energy as a small light bulb, the ACS remains inexpensive to operate, yet very effective.”

Backed by an industry-leading three-year warranty, Rain Bird’s new Algae Control System is easy to use and maintain. It offers superintendents peace of mind and a more attractive course while saving time and money. For more information, or for help choosing an ACS model, e-mail
