I have an aeration system but the pond is frozen over, am I still getting aeration? | Ponds & Lakes Q&A

Q: I have an aeration system but the pond is frozen over, am I still getting aeration?

Q: I have an aeration system but the pond is frozen over, am I still getting aeration?

Jenni – Monticello, NY

A: Even if you’ve been running your aeration system diligently throughout the winter to protect your fish, it is still possible for your pond freeze over. It is not uncommon for the cold weather to close up the holes created by your aeration system during a streak of particularly frigid winter days. Your pond is able to hold a substantial amount of oxygen which acts as a buffer for days where your pond is getting less than ideal air exchange. Even when frozen, your aeration system will continue to circulate and add oxygen to the water column. Typically a sunny or warmer day will provide the assistance your aeration system needs to re-establish ventilation holes in the ice and release any harmful gas that accumulated while the pond was frozen over.

If your pond stays frozen over for more than a week or two at a time you may want to consider using an ice auger to drill a couple holes in the ice around the perimeter of your pond. Do not venture out towards the center as your aeration system is constantly bubbling and weakening the ice. Never try to pound, crack or break through the ice to open a hole for air exchange as it will send pressure waves throughout the pond disrupting and possibly killing your fish. Positioning your aeration plates in shallower areas of your pond will make it easier for the surface water above the plate to remain open due to increased water movement reaching the pond’s surface.

If your pond still hasn’t thawed out with the help of warm weather, sunshine and shallow plate placement, inspect your aeration system to make it is properly functioning. If you are using an Airmax® Aeration System, make sure the air filter is clean and is being changed every 3 to 6 months. Check your pressure gauges and airlines for indications that the compressor is still producing adequate air flow. If your system is between 3 to 5 years old consider installing a maintenance kit which replaces all of the seals and wear and tear parts that lead to decreased system performance. If the pressure reads abnormally high it may indicate that your airlines are obstructed by ice or possibly pinched or crushed.

If your pond only stays frozen over for short periods of time there is no need to worry. The holes will open back up on their own and your pond will take care of the rest naturally. Continue to regularly inspect your aeration system for signs of trouble and ALWAYS exercise caution when venturing near the ice. Make sure there is a flotation device present at your pond both in the summer and winter.

How large of a hole will an aeration system keep open in the ice? I like to keep open water for ducks. | Ponds & Lakes Q&A

Q: How large of a hole will an aeration system keep open in the ice? I like to keep open water for ducks.

Q: How large of a hole will an aeration system keep open in the ice? I like to keep open water for ducks.

Mark – Concord, VT

A: No doubt those ducks will appreciate some open water in the winter, and an aerator is the best way to keep that hole open for them. Many factors will affect the hole’s size and how long it will remain open, but here are three important points to consider:

  1. Size of the System: Larger aeration systems will move more water, and all that water movement will create a larger hole that will stay open longer. If you want a bigger open area, consider a beefier aeration system.
  2. Depth of Water: Water depth matters, too. An ice-free open area in deep water is more difficult to maintain than one in shallow water, where there will be more water movement at the surface. If possible, plan your open water in the shallow areas of your pond.
  3. Weather: Mother Nature has her say, too. When it’s cold and windy, it’ll be more difficult to keep that opening ice-free. In fact, frigid temperatures can restrict the hole down to a couple of feet or less! But when the weather warms up, the hole can open to areas of 10 feet or more.

Ideally an aeration system should be matched to your pond’s size and shape, and run all season. Diffusers can then be moved to shallow water for the ducks during winter. Simply place the diffusers evenly across a small area in the shallow part of your pond so they can work together to keep a larger area open.

How can I keep my dock from getting destroyed by ice? | Ponds & Lakes Q&A

Q: How can I keep my dock from getting destroyed by ice?

Q: How can I keep my dock from getting destroyed by ice?

Rick – Merriam, IN

A: Ice can certainly do some damage to a dock. As water freezes, it expands. As it melts, it contracts. And all that freezing and melting business can wreak havoc on the wood and materials used to make the mooring.

So what can you do to protect your investment? If you have a floating or removable dock, it’s easy. Simply remove it from your pond and store it for winter. If you have a permanent dock, you have two options: a circulator with float, or a bubbler system. Here’s what you need to know about them.

Circulator with Float
A circulator, like the Kasco Circulator with Horizontal Float uses a motor and propeller to push water under the dock and up toward the surface. Kasco Water Circulators can be suspended from the horizontal float to create elongated patterns of water movement that discourage ice formation. With 5 angled positioning options, the flotation kit allows for easy adaptability for most situations. It can also be secured directly to your dock using the optional Universal Dock Mount.

Bubbler System
A bubbler system, like the Shallow Water Series™ Aeration System, uses a diffuser to create water movement under the dock and prevent ice formation. Diffuser plates connected to an air compressor pump air below the surface and agitate the water. Multiple diffusers used together can create large areas of open water, particularly when they’re placed evenly across a small area in the shallow part of the pond. Another benefit: They cost less to operate than a motor and prop.

Weather Watch
Whether you use a circulator or a bubbler system, remember that the weather will be the most influential variable in protecting your dock. The warmer the weather, the easier it will be to keep the ice melted; a warm, sunny day can open up a hole 10ft. or more. Cold, windy weather, however, can cause that hole to shrink to a couple of feet or less.

Good luck preventing that dock from being destroyed by ice!

If I’m going to shut my aerator down for the winter, when should I do it? | Ponds & Lakes Q&A

Q: If I’m going to shut my aerator down for the winter, when should I do it?

Q: If I’m going to shut my aerator down for the winter, when should I do it?

Syd – Jackson, WY

A: Ice skating, hockey, curling, broomball, ice fishing—part of the joy of having your own pond or lake is all the wintertime sports that can be played on the ice. These frosty, fun activities are the main reason why folks shut down their aerator for the winter, as keeping one running will create a hole in the ice and make the ice unstable.

If you plan to turn your lake into an ice rink this year, turn off, pull out and store your aerator before the ice begins to form. Why? Because if ice that forms on the water surface has been moving for even a short time, it can be porous and not suitable for skating. Even movement on one end of the lake and not the other can make the ice at the edges unsafe.

Here’s the shutdown process we recommend:

  1. Unplug and shut your aeration system down completely. It’s critical to do this before the ice starts to build on your pond’s or lake’s surface for the safety of those who will skate on the pond.
  2. Stow the cabinet and compressor away. Your airline and plate may stay in the pond, but the system’s cabinet and compressor should be stored indoors to keep dry and prevent condensation and rusting.
  3. Cover flex tube and airlines ends. Doing so will prevent debris from entering and plugging up the airlines.
  4. Have an emergency plan, just in case. While you’re prepping your lake for ice skating fun, now’s a good time to make sure you have water safety items available, too, like a Life Ring. If the ice breaks, a safety preserver like this can save someone’s life.

If you’re not using your pond for winter activities, keep your Airmax® Aeration System operating all season long so your fish will survive a winter fish kill caused by lack of oxygen. Don’t forget to move your diffuser plates out of the deepest water. This will give your finned friends a safe zone and prevent the super-cooling effect that happens in the chilled winter water.

I know my fish will go to the bottom of the pond for the winter, but do I need to do anything for turtles? | Ponds & Lakes Q&A

Q: I know my fish will go to the bottom of the pond for the winter, but do I need to do anything for turtles?

Q: I know my fish will go to the bottom of the pond for the winter, but do I need to do anything for turtles?

Virginia – Brillion, WI

A: Turtles are smart critters. Unless your terrapins are terrarium-dwellers that aren’t accustomed to the great outdoors, they instinctively know what to do to prepare for winter. They take their cues from Mother Nature—so you can simply let them do their thing! Read on to learn more.

Winter Home-Sweet-Home

When air and water temperatures start to chill and their food source become scarce, turtles will slow their metabolisms and look for a place to hole up for the winter. Different types of turtles prefer different types of winter homes; water-loving turtles will swim to the bottom of the pond while land-based turtles, like a box turtle, will burrow in the dirt or mud at or near the pond surface, where they’ll stay warm and cozy.

Metabolism Changes

Just like fish, turtles will stop eating as their metabolism naturally slows to a cold-weather crawl. They’ll start to hibernate—or brumate, as termed in herpetology—when they’ll require very little oxygen, their heart rate will slow to just a few beats per minute and they’ll sleep the winter away, only to wake up in the spring when temperatures increase again.

Provide a Welcoming Environment

Though turtles don’t need a lot of oxygen while they’re hibernating, they do appreciate a healthy pond with clean, O2-infused water. Provide that to them by completing your fall-maintenance chores, like cleaning up dead or dying debris, and keeping your aeration system running over the winter. That moving, oxygenated water will ensure your shelled pond pals will get a good winter’s sleep.

My water quality is good, but what should I do over the winter to keep it that way? | Ponds & Lakes Q&A

Q: My water quality is good, but what should I do over the winter to keep it that way?

Q: My water quality is good, but what should I do over the winter to keep it that way?

Quintin – Pine Bluff, AR

A: When it comes to doing chores at the pond, it is easy to let your guard down this fall. Thanks to your hard-working bacteria, the water is clean and clear with minimal algae, and your fish are happy. You have nothing to do but coast into winter and hibernate until spring.

Not so fast.

As water temperatures drop, those bacteria and algaecides stop fighting off excess nutrients and cold-temperature plant growth. They are no longer effective at their jobs, and so you need to step in and help. Here’s what you can do to maintain pristine water quality over the winter.

  • Add Some EcoBoost™: Formulated to bind organic debris suspended in the water, Pond Logic® EcoBoost™ helps to clear water and enhance beneficial bacteria. It also provides more than 80 trace minerals to fish, keeping them healthy over the winter. EcoBoost™ has no temperature restrictions, so you can use it all year round. Simply mix the powder with some water in a pail and pour it in the pond.
  • Tint with Pond Dye: During the cold temperatures and even iced-over conditions your pond’s bottom can still be exposed to sunlight. Pond Dye can be used year-round – winter included – to shade your pond from the sun’s UV rays. The dye also imparts a dramatic hue to the water, giving it a great look when it ices over.
  • Aerate and Oxygenate: You can also improve water quality through the winter by keeping the oxygen levels up and water circulating. If you are not going to use the pond for ice-skating or hockey, we recommend you use a subsurface aerator, like the Airmax® Aeration Systems. The system will keep the air bubbles flowing throughout the water column while maintaining a hole in the ice for gas exchange. If you have a fountain running, remove it and store it for the winter. Ice can damage the motor in the pump.

Before you hibernate for the winter, spend a few hours out at the pond to prepare it for winter. When you look out on a crystal clear pond in January, you’ll be happy you did!

I heard you can lose fish during the winter. How do I prevent a winter fish kill? | Ponds & Lakes Q&A

Q: I heard you can lose fish during the winter. How do I prevent a winter fish kill?

Q: I heard you can lose fish during the winter. How do I prevent a winter fish kill?

Jon – Little Suamico, WI

A: Imagine being cooped up all winter long in a room with no ventilation and no fresh air. Pretty claustrophobic, right? Now add the stench of decaying garbage and other waste buildup … it’s likely you wouldn’t last until spring.

It’s a similar situation with your fish.

In colder climates that freeze over the winter, decomposing vegetation and waste beneath the ice layer releases toxic gases that build up, displacing the oxygen that the fish need to survive. When that O2 is replaced with ammonia and other harmful gases, the result can be a winter fish kill.

So how to do you prevent this from happening? Aeration with an Airmax® Aeration System.

Open a Window!

An Airmax® Aeration System sized for your lake or pond moves the water below the frozen surface, which keeps an air hole open in the ice. This ventilation allows the harmful gases to escape while bringing in fresh oxygen for your fish. The aeration also injects oxygen into the water via the bubbles that come out of the diffuser or air stones.

Provide Year-Round Oxygen

For the health of your fish, we recommend you run an aeration system year-round—unless you plan to use the pond for winter activities, like ice skating or hockey, that require a solid and safe sheet of ice. In that case, follow the instructions in your product manual to safely turn off your system.

Create a Warm Zone

If you plan to run your system year-round, move the diffuser plates into shallower water during the winter months. This will allow your fish to hunker down in your pond’s warmer depth for the winter. It will also prevent the rare “super cooling” effect, in which the water temperature dips below freezing and over chills your fish.
