Q: Is there any maintenance I should do when I pull out my fountain for the year?

John – Epping, NH

A: Decorative fountains add beauty to your waterscape while pumping some extra oxygen to your pond or lake, but they are designed to be used in the warmer months – not winter. So when you’re ready to pull out your fountain for the year, follow these six steps to ensure it’ll be ready for use again in the spring:

  1. Pull Unit from the Pond: To remove your fountain from the water, simply release it from its mooring line and gently reel it in. Leave the mooring line stakes in place to make it easy to reinstall it in the spring. You’ll save time from having to place the fountain in position.
  2. Clean Your Fountain and Lights: As your fountain runs through the spring, summer and fall, algae and other debris accumulate on the motor, lights and float. This unsightly debris acts as an insulator that traps heat around the motor, which could cause overheating when you reinstall it in the spring. Get out your scrubber and polish your surfaces while they’re still wet. Some expert advice: It’s best to clean that gunk off before it dries on.
  3. Inspect for Damages: Normal wear-and-tear and curious critters can cause nicks and chew marks in the cord that will need to be repaired, so check it for damages. Also, if you haven’t performed routine maintenance on your unit, like changing oil and seals, winter is the perfect time to do so while your fountain is out of the water and in your workshop.
  4. Cover the Cord Ends: Once your fountain is cleaned and repaired, cover your power cord ends by covering them with a vented plastic bag to keep dust and debris out while it’s in storage.
  5. Store in Safe Spot: Find a safe, frost-free place to store your fountain over the winter. Ideally, stash it in your garage, basement or other place that won’t freeze.
  6. Keep Aeration Running: Unless you plan to use your pond for recreation, like hockey or ice skating, your pond will need oxygen through the winter. Continue to use your diffused aeration system to maintain a hole in the ice for ventilation and gas exchange.

Follow these simple maintenance steps and you’ll be ready to reinstall your fountain in the spring – once the ice melts, that is!

I’ve tried sprays and other types of bug control. Is there anything else I can do to reduce the mosquitoes by my pond? | Ponds & Lakes Q&A

Nancy – Lima, OH

A: Nothing ruins a pondside shindig faster than a swarm of blood-thirsty mosquitoes. The buzzing, biting, irritating bugs are the bane of pond owners. Besides causing itchy welts, these little pests can transmit dangerous and deadly diseases, like malaria, dengue, yellow fever, West Nile virus, dog heartworm and equine encephalitis.

Yep, they’re a nuisance—but their population can be controlled. Here’s what we recommend.

Remove Food Source

Ponds with lots of plant matter and algae are perfect for feeding baby mosquitoes. Those little wigglers and tumblers (technical terms for developing mosquito larvae and pupae) gobble through the greens, but you can minimize their feeding frenzy by maintaining your pond and eliminating their food source.

Move the Water

A female mosquito prefers to lay her eggs in stagnant water that’s full of algae, plankton, fungi and bacteria, so your next plan of attack should be to churn the water with a fountain, like our AquaStream™ Fountain, or an Airmax® Aeration System near the area where you sit. The waves will make her think twice about calling that part of your pond home.

Grasses Be Gone

Because adult mosquitoes live among the debris surrounding your pond, you want to keep those grasses cleared out. Use some herbicide, like Shoreline Defense®, to kill aquatic weeds and grasses. And pull out your weed removal tools, like your weed cutter, rake and debris skimmer, and remove the dead plants, overgrowth and other potential hiding spots – at least in the area where you hang out most often.

Help from Finned Friends

Mosquito-eating pond life, like tadpoles, minnow, bass, bluegill and catfish, love noshing on the little larvae and pupae. If you don’t already have a fish population living in your lake, consider adding some! The American Mosquito Control Association, in fact, recommends adding predacious minnows or native fish to lakes and ponds for biological control of the insects.

Use Mosquito Dunks or Bits

Mosquito dunks or bits are a lifesaver for folks with still ponds and other standing water pools on their property. These handy little disks or bits contain Bt-israelensis (Bt-i), a specially formulated biological pesticide designed to kill mosquito larvae. You simply toss them in your pond or lake and they’ll provide relief for up to 30 days. Plus, they’re safe for use around wildlife, pets and humans.

Unfortunately, mosquitoes are part of life with a lake or pond. With some pond and landscape maintenance, aeration, water movement, biological control and, if necessary, chemical control, however, you can keep the buzzing swarms at bay.

I have an old sump pump. Can I use it to create a fountain for my pond? | Ponds & Lakes Q&A

Q: I have an old sump pump. Can I use it to create a fountain for my pond?

Q: I have an old sump pump. Can I use it to create a fountain for my pond?

Nick – Linwood, KS

A: Sounds like you want to do some “upcycling” and save a little money while making use of old equipment that’s sitting around. What a fun project, and something you can show off to your friends!

Yes, you can certainly transform that old sump pump into a fountain for your pond – but whether it works will depend on what you want to do with that fountain.

Sump Pump Fountain?

A sump pump is traditionally used to remove water that’s collected in a basement. It pumps the water away from the house to a place where it’s no longer problematic. It’s not really designed for long-term continuous use, and so using a sump pump to create a spraying fountain might decrease its life expectancy. Replacing it could be costly.

There are other factors to consider, too. A sump pump might cost more to operate. You’ll still need to create a way to anchor or suspend the motor and create a spray. And you’ll need to extend the power cord long enough to reach a power source safely – which will require trial and error or fancy engineering.

If you’re a build-it-yourselfer in search of a challenge and plan to not use it for long-term continuous use, go for it! If not, consider purchasing an actual fountain.

Out-of-the-Box Easy

For those who are looking for an easy, cost-effective and trouble-free way to add some splash to a pond, buying a pre-manufactured decorative fountain has its benefits, including:

  • They come with pumps that are designed to be used as a fountain, so they create much more water movement and a heavier spray that’s less affected by wind and pump-clogging floating debris.
  • They can be used as an aeration system in ponds less than 6 feet deep.
  • All the engineering work is done for you! After a quick installation, you’ll have a decorative spray and a power cord that’s long enough to reach the shore.
  • Some, like the AquaStream™ Fountain and Light Combo Kits, come with decorative options, like lights and different spray patterns.

Whichever you choose, it’s always a great idea to create movement and aerate the water. Your fish and plants will appreciate it, and you – and your guests – will, too!

A: It sounds like that strange stuff floating in your pond is pollen – particularly if you’ve had the same issue at about the same time in previous years. How do you identify it and get rid of it? Read on to learn more about fixing your pollen problem.

Just on the Surface

Looking like an oil slick floating on top of your pond, the pollen’s hue may vary in shade from white to yellow to green, particularly if there’s a little algae mixed in. The substance will break apart if you run your fingers through it, and it often forms a circle around aeration plates.

The tiny pieces of pollen stay on the surface thanks to something called surface tension. Pollen is light, and when it lands on still water that’s not moving it remains there. Unless something breaks the water tension, like rain or the splash from a fountain, the pollen will continue to float and coat the water surface.

Saying ‘Goodbye’ to Pollen

If you want to get rid of that unsightly pollen, here’s what we recommend:

  1. Add Aeration: Aeration, like our Airmax® Aeration Systems, churns and moves the water below the surface, and that action will help break down the surface tension from the bottom up. We offer a range of aerator sizes to fit any pond, from small ornamental features to large water gardens or fish ponds.
  2. Add Some Splash: While the aerator cycles the subsurface water, a decorative fountain like our AquaStream™ Fountains, or even a garden hose (in desperation!) will break the water tension and dissipate the pollen. Check out the different styles, sizes and spray patterns of our fountains – they look great and work hard!
  3. Wait It Out: Pollen will eventually dissipate with the changing of the season or after a heavy rain. If you’re patient and wait it out, the problem will resolve on its own.

Green Be Gone

Is the pollen in your pond a bit green? You could be battling an algae and pollen problem. In addition to resolving the situation with aeration and a decorative fountain, use Algae Defense®. It’s a fast-acting, algae-killing liquid formula that can be applied directly to your pond with a sprayer – so it’ll destroy the green stuff and dissipate the pollen.

Will my fountain be enough to keep my fish safe this winter?| Ponds & Lakes Q&A

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

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?

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!
