"We use many Kasco units with the Universal Dock Mount option in the summer for water quality purposes. They keep organic material and debris from floating into our marina. They have been effective and dependable."
- Diane Schabach, Harbor Master of Menasha Marina

Pond CirculatorKasco water circulators provide valuable benefits to you
in every season of the year.
Circulator used in a pond to eliminate stagnant water.
During the summer months, they are used to mix and agitate stagnant water to help reduce aquatic plant growth and inhibit mosquito reproduction.

Pond CirculatorIn 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, Water Circulators can be used to keep areas of water open to help prevent winterkill on fish populations and protect permanent structures from ice damage.

Kasco water circulators are ideal for creating directional water flow in your pond or lake. This transforms still, stagnant water into a stream environment and helps add vital oxygen. Still, stagnant water promotes the growth of unwanted surface and bottom vegetation such as algae. By eliminating the stagnant water, the water circulators help limit the growth of the unwanted aquatic plants and keep your pond cleaner.

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.

Kasco Water CirculatorClick on the right picture to see a slide show of a test performed at Southern Illinois University on October 6, 2004. A Kasco F2400CF, 1/2hp water circulator was placed in a 102' x 42' x 7' pond containing roughly 225,000 gallons of water with about 1/5 gallon of pond dye added to aid in visualizing the mixing action. The pictures were taken every 30 seconds. Watch how fast only a 1/2hp Kasco water circulator can thoroughly mix this pond!

Pond CirculatorKasco 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.

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

Pond CirculatorKasco 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.
Kasco water circulators can be used to help prevent winter-kill conditions and protect permanent fixtures in your pond or lake. During harsh winters with thick ice and heavy snow pack, your pond can experience a fish die off due to low oxygen levels. The heavy snow and ice prevent sunlight from penetrating into the water causing the existing aquatic vegetation to die off. As the vegetation dies, the decomposition process uses up much of the available oxygen in the pond. As the winter progresses, the oxygen levels continue to decrease and eventually, your fish may begin to die.

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.

Water Circulator MethodsKasco 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.

菜豆生育過程中,主要吸收鉀和氮較多,還要吸收一定量的磷和鈣,才能良好發育。結莢期吸收磷鉀量較大。磷鉀肥對菜豆植株的生長發育、根瘤菌的發育、花芽分化、開花結莢和種子的發育等均有影響。缺乏磷肥,菜豆嫩莢和種子的品質和產量就會降低。缺鈣,幼葉葉片捲曲,葉緣失綠和生長點死亡。缺硼,則根係不發達,影響根瘤菌固氮,使花和豆莢發育不良。 耐陰半陰(大概3-4小時日照) 應選擇耐陰的蔬菜種植,如萵…


Dried lemons are actually limes and are used heavily in Persian Gulf and also Iranian cuisine where they add a strong bitter flavor in addition to sourness. They are made by boiling ripe limes in salt water, and then sun drying until the insides turn black. The outside color varies from tan to black. They are sold whole or ground.

Black Lime is a spice used in Middle Eastern dishes. It is made by boiling fresh lime in salt water and sun drying until the insides turn black. The outside color varies from tan to black. It is sold whole or ground.

USE Black limes are usually used in legume, seafood or meat dishes. They are pierced, peeled or crushed before adding them to the dish. After cooking they become softer and edible. They can also be powdered and added to rice dishes. Powdered black lime is also used as an ingredient in Gulf-…


為何冰箱冷凍室非得是零下18度? 不少家庭的冰箱有led面板,可顯示冷藏室和冷凍室溫度。每次看到那個零下18℃,不少人,包括筆者在內就會禁不住提出一個小疑問:為什麼冷凍室溫度非得是零下18℃?最多零下1℃不就結冰了嗎?搞這麼低溫度實在是浪費電呢。















一般來說,能引起食物腐敗和食物致毒的嗜溫菌,在低於3 ℃情況下不產生毒素,當然,個別菌種例外。

而對於嗜冷菌,一般得在零下10 ℃到零下12 ℃時才會停止生長。

有的黴菌甚至要到零下15~零下18 ℃時才會停止生長。
