Q: Will my fountain be enough to keep my fish safe this winter?

Holly – Gorham, ME

A: If your pond freezes over in the winter, a fountain won’t do you or your fish much good. It’s not designed to be run or left in the pond during icy conditions. The ice can damage the float or create a barrier that prevents water from passing through the spray nozzle. That could cause the motor to run dry and stop working. And that’s not good.

Instead, we recommend completely removing your fountain and a run a bottom diffused aeration system instead.

Before the Ice Forms

Autumn is the perfect time to remove the fountain from your pond before the ice forms. When unplugging the motor and pulling it ashore; inspect the cords, motor and lights for any damage. After sitting in a pond all summer, chances are you will have to clean the fountain and lenses from any algae, build up or debris. Once your fountain is ready to be stored, place it in doors until spring.

Below the Surface

Now that you have removed the fountain from the pond, it is a good idea to protect both your fish and boating dock from ice damage by adding an aeration system. Aeration keeps the oxygen levels up and the water circulating. Depending on how close the diffuser plates are to the surface or dock, aeration can also keep a hole open for gas exchange, and provide a place for ducks to gather when everything else is frozen over.

Keep your fish safe and happy this winter by giving them surface and subsurface aeration. They’ll appreciate it more than just your fountain!

What is supercooling? | Ponds & Lakes Q&A

Q: What is supercooling??

Q: What is supercooling?

Aloma, Warroad, MN

A: Supercooling is uncommon, but it can occur in lakes and ponds, particularly in the northern states. Here’s what you need to know about it and how to prevent it from happening.

In the winter time water stratifies in pond and lakes without proper aeration when surface temperatures are extremely cold, creating what’s called a thermocline. A thermocline happens as warmer water about 39°F or so – sinks to the bottom, while colder water about 32°F or so – rises to the top. Very little mixing of the layers occurs, particularly in calm weather.

Supercooling could become an issue if you’re running a surface aeration system in shallow ponds with fish. The fish prefer to stay on the bottom of the pond in the warmer pockets of water during the winter. They’re in winter-hibernation mode, and all they want to do is be in a stress-free spot until spring.

As the aerator circulates the warmer water with the cooler water at the surface, the overall temperature could drop. In extreme cases when the temperatures are well below 0°F, the water temperature can actually drop below its freezing point without becoming a solid – a rare process known as supercooling.

If the water gets too cold, your fish have nowhere warm to go. Living without their warm hangout spot could compromise their oxygen supply and immune systems, making them vulnerable to parasites and diseases.

The best way to deliver oxygen to your fish is with a bottom diffused aerator, like an Airmax® Aeration System. You can keep it running without creating an inhospitable environment for your finned friends by simply moving your diffuser plates closer to the surface or turning half of them off.

If you relocate the diffuser plates to a spot that’s about half the depth of your pond or run only 50 percent of them, a pocket of warm water will remain for your fish at the bottom. You’ll continue pumping oxygen into the water and keeping a hole in the ice for gas exchange without having to worry about freezing your fish.

Isn’t my fountain enough aeration for my pond? | Ponds & Lakes Q&A

Q: Isn’t my fountain enough aeration for my pond?

Kelly – Harrisville, WV

A: Fountains deserve a lot of love. As they launch water into the air, they add dramatic movement and visual appeal to the landscape. The sound of stirring water makes anyone within earshot relaxed and tranquil. Fountains add a good deal of oxygen to the pond as the tiny droplets make contact with the air and fall back into the pond. But do they provide enough aeration? It all depends on your pond’s depth.

More Than 6 Feet Deep…

If your pond is more than 6 feet deep, your fountain does not provide enough aeration. Why? The best way to aerate the pond is to circulate the entire body of water at the same time. Because a fountain draws water from the top of the water column only, the water deeper than the 6-foot mark remains untouched – and oxygen deprived.

An aeration system, like the Pond Series™ Aeration System, will pump air to the diffuser plate positioned at the bottom of the pond. The rising bubbles then lift and aerate the water from the bottom up, ensuring that the entire pond is circulated and oxygenated.

Less Than 6 Feet Deep…

If your pond is less than 6 feet deep, your fountain is good to go. Because enough oxygen is exchanged at the pond’s surface, you don’t need additional aeration – but you do need to worry about the fountain’s spray pattern and horsepower.

The most effective shape for aeration is the “V” shape or “Classic” pattern, like the one included in the AquaStream™ fountain. It does the job simply and effectively. The more decorative the spray pattern, the less likely it is to adequately aerate your pond because more energy is spent on creating the patterns than on moving the water.

As for horsepower, when using a fountain for aeration purposes, go with a 1.5 HP motor per acre. Remember that depending on your pond’s size and shape, you may need more than one fountain to properly aerate. If you’re using a fountain for decoration only, you can go with a 1 HP per acre motor instead.

Weighing the Cost

A fountain can be costly to operate, but an aeration system – which has lower operating costs when compared to a fountain running 24/7 – is an affordable alternative. Whichever method you choose, don’t go without aeration, because that could cost you more in the long run!

A: Fountains do more than create an attractive splash in your pond or lake. They also allow for greater gas exchange at the water’s surface, expelling dangerous ammonia and drawing in healthy oxygen for your fish and other sub-surface critters.

When spring rolls around, it’s time to reinstall your fountain – but before you do, be sure to check your Farmer’s Almanac or with your meteorologist. Make sure there’s little chance of the pond icing over again.

Once you’re sure that temps will remain above freezing, perform some quick maintenance tasks before submerging the fountain and anchoring it into position, including:

  • Clean It Up: Pull out a power washer and spray down the motor so built-up material doesn’t trap heat.
  • Check the Cord: Inspect the power cord for cuts.
  • Make It Muskrat-Proof: Protect the cord with ratcord (power cord sleeve) if you have muskrats in your area.
  • Maintenance Visit: Send the motor in for regular seal and oil maintenance if you haven’t done so in a few years.

When you put your fountain back into place, make sure the mooring lines are snug enough to keep it secure. When anchoring with blocks at the bottom of the pond, make sure the lines are spread far enough apart so the fountain doesn’t spin from the force of the motor, which could cause the lines to get tangled.

As soon as you’ve put your fountain back in place, add your first dose of Pond Dye to the water so the spraying action will disperse the color evenly. Nature’s Blue™ or Black DyeMond™ will shade the water, minimize algae blooms and give your landscape a natural-looking pop of color

When should I remove my fountain? | Ponds & Lakes Q&A

Q: When should I remove my fountain?

Q: When should I remove my fountain?

Ray – McDermott, OH

A: Among your fall-preparation chores is removing the fountain and storing it for winter, particularly if you live in an area that endures freezing temperatures. Why? When ice forms, the cold stuff might damage the float. Or it could create a barrier that prevents water from passing through the spray nozzle, causing your fountain run dry and destroying your motor.

Your best bet: Remove the fountain before the ice begins to form. Sure, you could wait until a thin layer develops and then remove it—but that means you have to get wet and messy when it’s freezing. Not fun. Get a jump-start now before temperatures get too frigid.

Here are four easy steps to pulling out and storing your fountain for the winter:

  • Pull the Plug: Turn off the power to the fountain and pull it ashore. Most units have a quick disconnect at the motor that allows you separate the fountain from the main power cord.
  • Scrub Down: Wash down the fountain and float assembly to remove any algae or debris that has accumulated over the season. If you have a pressure washer, use it. It’ll make short work of even the dirtiest fountain.
  • Electrical Check: Inspect wiring and electrical cables for signs of wear or damage. If your fountain has lights, check for burned out or damaged bulbs and lenses.
  • Safe Storage: Once your fountain is cleaned and inspected, store it in an upright position in a climate-controlled location, like a heated pole barn or garage, until spring.

Now that it’s out and cleaned, you might want to consider sending your fountain to a licensed repair facility for routine maintenance tasks, including oil changes and/or seal replacements. Be sure to read through your user’s manual for special instructions and maintenance plans to keep your fountain running at its very best.

If you don’t plan on using the pond for ice skating or other winter recreation, now is a great time to install an Airmax® Aeration System to keep your pond oxygenated and healthy through the winter months. The aerator will circulate the water while keeping a hole in the ice surface, which will bring oxygen in and allow toxic gases to escape.

Why is there fog on my pond in the mornings? | Ponds & Lakes Q&A

Q: Why is there fog on my pond in the mornings?

Joann – Knoxville, TN

A: An enshrouding and ethereal harbinger of fall, misty morning fog conjures a sense of mystery—but why the fog appears isn’t so mysterious once you understand what it is and how it forms.

Fog Defined

Fog is simply a concentration of low-lying water vapor in the air. In the fall, these tiny liquid water droplets often form over bodies of water like your pond or lake.

Temperature Mix

Fog forms when cool air and warm water meet and, more specifically, when the difference between the temperature and the dew point is less than 4° Fahrenheit.

You see, in your pond, the water, heated by the sun, stays warmer than the air temperature during the cool night. When the cold layer of still air settles over your pond, warm water vapor from the pond evaporates, entering the cool air above it. The cool air then traps the concentrated water vapor and fog forms. In the morning, as the sun heats the air and temperatures rise, the water vapor evaporates and dispels.

Fog Fighters

If you don’t like fog and prefer to use your pond early in the morning before the misty stuff dissipates, consider installing one of Kasco’s Decorative Fountains. A fountain adds oxygen to the pond—but that’s not all. It also creates movement above the water, which prevents cool air from settling on the water surface. This will help prevent fog from forming.

John – Wapakoneta, OH

A: Sitting out on the deck and viewing a beautiful fountain display as well as hear that relaxing sound of water is pond enjoyment to us. Having a fountain in your pond is a great way to add tranquility to your home. What more could you ask for?

Many people are drawn to a fountain’s show-stopping appeal, but will they aerate a pond as well? The answer to this really depends on a couple factors: the pond’s depth and the type of fountain pattern.

Pond Depth: Fountains can be great aerators when the pond has less than 6′ of depth. The reason for this is because the best way to aerate is to circulate the whole body of water at the same time. A fountain will only draw water from the top of the water column, which is water that already contains oxygen from the air to water oxygen transfer. The pond’s bottom will remain untouched if it is deeper than 6′. If your pond is less than 6′ deep, then all you have to worry about is the spray pattern.

Fountain Spray Pattern: The spray pattern of a fountain makes a huge difference in how much aeration is produced. Usually the more decorative the spray pattern, the less likely it is to aerate your pond properly. This is because more energy is spent on creating the decorative pattern than there is moving the water. The best spray pattern to use for a fountain is a “V” patterned fountain like the Kasco VFX series fountain.

Because of the varying fountain choices there are some rules of thumb to go by. When using a fountain for aeration purposes, you want around 1.5HP per acre. If using a fountain only for decoration, go for 1 HP per acre.

If your pond is deeper than 6′ of depth, than the best method of aeration is an Airmax® Aeration System. The Airmax® Aeration System will pump air to the diffuser plate located at the bottom of the pond, and the resulting column of rising bubbles lifts and aerates the water. By starting from the bottom, this will ensure that the whole body of water is properly circulated as well as aerated. Airmax® Aeration Systems have lower operating costs than running a fountain 24-7.
