During the summer months, they are used to mix and agitate stagnant water to help reduce aquatic plant growth and inhibit mosquito reproduction.

In the spring and fall, the can help reduce thermal stratification in deeper bodies of water to help prevent or limit the negative effects of pond turnover.

Finally, in the winter months, circulators can be used to keep areas of water open to help prevent winterkill on fish populations and protect permanent structures from ice damage.

Stagnant water contributes to rapid mosquito reproduction, including those that may carry the West Nile Virus. Creating a stream environment helps limit mosquito reproduction and thereby helps control the overall population of mosquitoes in your area.

Circulators can be used to extend Waterfowl hunting with more open water.

Kasco water circulators have been used with great success to extend waterfowl hunting seasons as well. Rather than a short season due to cold weather and freezing water, with a Kasco water circulator, an open area can be maintained to attract birds.

Since most hunting blinds do not include electricity, most hunters who use Kasco water circulators will operate the unit with a generator before sunlight to open the area. Then before shooting hours, will turn the generator off to avoid scaring away the waterfowl.

Kasco water circulators are great tools to limit the negative effects of spring and fall turnover. Ponds in geographic areas that see large seasonal temperature swings often have spring and fall turnover. Spring and fall turnover occurs when deep, stratified (large temperature differential between surface and bottom water separated by a thin layer of water called a Thermocline) water "turns over". In spring, the surface water is heated by the sun to about 39 degrees and becomes more dense than the colder, de-oxygenated bottom water. When the warm surface water becomes too dense for the colder water to support, the pond water will turn over and have the colder water on the surface. This causes the de-oxygenated water to mix with the oxygenated surface water and cause an overall lower oxygen level. When large numbers of fish are present, oxygen levels can become low enough for a fish die off to occur. In Fall, the exact opposite occurs. The surface water is cooled by cooler nighttime periods and when the surface water is around 50 degrees, the pond again turns over. Kasco water circulators can be angled downward to destratify ponds to about 18' in depth. By destratifying the water, Kasco water circulators move cooler de-oxygenated water from the bottom to the surface where the water can be warmed and oxygen diffused through the air-water interface causing the elimination of the thermocline and large temperature differential and increasing oxygen levels throughout the entire water column and improve your lake or pond aeration.

Circulator used for winter kill prevention and to protect docks from ice damage.

A Kasco water circulator will mix the water and move warmer, bottom water to the surface to keep an area of the pond open. Only 1% of the ponds total surface area needs to be ice free to prevent winter-kill situations. The cold water will become oxygenated by coming in contact with the air and prevent winter-kill on your pond.

Kasco water circulators positioned around docks and/or boats can prevent costly ice damage by keeping an area ice free around your valuables. Depending on your situation, they can be mounted in three different methods (shown below)



ROPE SUSPENSION: The Water Circulator can be mounted in either a vertical or angled position with ropes or cables.

UNIVERSAL DOCK MOUNT: Kasco also offers an optional dock mount, which allows for either vertical or several angled positions.

HORIZONTAL FLOTATION KIT: Kasco Water Circulators can be suspended from the flotation kit to create elongated patterns of water movement. The unit rests less than two feet below the surface and is ideal for shallow water or where there is no dock or place to suspend the unit. With 5 angled positioning options, the flotation kit allows for easy adaptability for most situations.

All models include a horizontal flotation kit and two 50' braided nylon mooring ropes and are available with 50', 100', 150', 200' or 250' SJTOW underwater rated electrical power cords.
