Q: When I start my aeration system up do I need to turn it on for only a few hours a day like when it was installed?

Chris – Alpena, MI

A: Yes, gradually starting up your system for the season will avoid any quick turnover in your pond. Ideally, your aeration system should run all year long. By running it all year long, this will prevent possible winter fish kills. But if you shut your aeration system down in the winter for recreational purposes, you will want to start it back up when the ice starts melting off your pond. In addition to gradual start-up follow the steps below to prepare your system.

  1. Re-level Your Cabinet: Take your cabinet and system back outside and get it on level ground again.
  2. Change Your Air Filter: Your air filter, which prevents debris from entering your air compressor, can be cleaned periodically to remove light debris – but it should be replaced every three to six months for maximum system performance and longevity.
  3. Check and Clean Side Intake Air Filters: Take a look at your side intake air filters on your cabinet, and make sure they’re clean and unobstructed.
  4. Ensure Cabinet Fan Works: To make sure fresh air will tunnel evenly through your cabinet, flip on your fan and verify that it’s working properly.
  5. Clean Membrane Diffuser Sticks: Though they’re virtually maintenance-free, these diffuser sticks, which deliver the air bubbles to the water, should be cleaned and inspected or replaced before they are turned on for the season. View your owner’s manual for more information.
  6. Start Your Compressor – Gradually: To prevent shocking your pond, follow your aeration system’s initial seven-day startup procedure. On Day 1, run the system for 30 minutes and then turn it off for the rest of the day. On each day following, double the time: Day 2, run for one hour; Day 3, run for two hours; Day 4, run for four hours; and so on. On Day 7, begin running it for 24 hours a day, seven days a week.
  7. Pressure Check: Once your system is up and running, make sure that its pressure gauge stays within the normal range of 5 to 10 psi. An easy way to do this to mark the gauge upon initial start up and check it regularly to verify pressure has not significantly risen above or dropped below your initial reading. Please note, this does not apply to Shallow Water Series™ Aeration Systems. It is also recommended to install a maintenance kit every 6-12 months, so if you find that your compressor is not producing as much airflow as it has in the past it may be time to perform some additional maintenance.

Following these simple steps will guarantee a smooth start to aerating your pond this spring. If you’re ever in doubt, check out your owner’s manual or contact us at 866-766-3435.

I spend a lot of time trying to kill algae, and sometimes it doesn’t work. Do you have any tips? | Ponds & Lakes Q&A

Q: I spend a lot of time trying to kill algae, and sometimes it doesn’t work. Do you have any tips?

Vince – Columbia City, IN

A: Frustrating, isn’t it? You spend hours upon hours pondside, dosing the water with algaecides and raking out algae-feeding plant matter and detritus, only to see the green menace return weeks – if not days – later. Is there a way to control the nuisance algae that’s turning your pond into pea soup?

You bet. Below are our top recommendations for battling the algae. If you follow these guidelines, you’ll have that green menace under control in no time.

#1 – Treat Only Actively Growing Algae
When using algae control products in your pond or lake, the algae must be present and actively growing. Why? Because the chemicals need to make direct contact with the tiny organisms and absorb into their cells for them to be effective; if there’s no living algae, the chemicals will land in the water and become diluted, and therefore ineffective when the green stuff blooms.

#2 – Treat When Weather Is Favorable
Algae can grow in cold temperatures – even frigid, depending on the species – but algaecides aren’t so tolerant. The pond water must be warmer than 60°F for the chemicals in them to work. Apply your algae treatment on a sunny, mild day when rain is not expected in the immediate forecast. This will allow the chemicals to adequately absorb into the algae. As always, read the product label for instructions and specific temperature requirements.

#3 – Treat Only a Third at a Time
When temperatures heat up and the algae dies off, that combination of warm water and decaying plant matter reduces the amount of oxygen available to fish and other living critters in the pond. Keep them in an oxygen-rich environment by treating the pond in small sections and wait 7-10 days before moving to the next section. In addition, keep your aeration system or fountains running during treatment to continue circulating and oxygenating the water.

#4 – Read the Product Label
Different algaecides have different active ingredients, inert ingredients and specifications, so always read your product’s label for appropriate protective equipment and application rates. Pay special attention to warnings concerning water use and restrictions in ponds used for irrigation, drinking and swimming, as well as in ponds that house certain types of fish. If you have trout, which are sensitive to copper-based treatments, test the carbonate hardness levels and ensure they are above 50 ppm prior to treatment. If they’re above that, use another treatment, like Hydrothol®, that contains no copper.

#5 – Follow Up with Airmax® Ecosystem Pond Management Program
Algaecides are a great tool that can temporarily clear up pea soup water, but they do little address the actual problem causing the algae – which is excessive nutrients and organics. By following your treatment up with proactive pond management practices, such as aeration and natural water treatments like MuckAway™, you will reduce the accumulation of dead organic material, which will help to keep your water clear season after season.

Why did I lose my fish? | Ponds & Lakes Q&A

Q: Why did I lose my fish?

Q: Why did I lose my fish?

James – Willmar, MN

A: After a long, roller coaster winter, there’s nothing more disappointing than returning to your pond to find your fish floating and bloated in the water. This winter fish kill, or “winterkill,” can happen when the ice sheet on your pond prevents gas exchange and reduces the amount of dissolved oxygen in the water, ultimately causing your fish to suffocate. Shallow lakes, ponds and streams are particularly vulnerable to winterkill.

What causes it, and how can it be prevented? Read on to learn more.

Starved for Oxygen

Winterkill occurs when ice and snow cover your pond or lake for long periods of time. That solid sheet of cold stuff seals off the water, stopping oxygenation and gas exchange at the surface, but that’s not all it does. The ice and snow cover also prevent sunlight from reaching pond plants, which normally produce sub-surface oxygen via photosynthesis. Add to that a lake full of decomposing organic matter releasing toxic gases that are trapped under the ice, and your poor fish do not have enough oxygen to survive.

The ones that do survive are not finned superheroes, but they are more tolerant of a low-oxygen environment than their dearly departed cousins. The species type and size makes a difference, too, in their ability to deal with less-than-optimal living conditions.

Stayin’ Alive

Unfortunately, you cannot bring your fish back to life, but you can prevent winterkill from happening in the future. We recommend a simple, two-pronged approach:

  1. Aeration: Aerate your pond year-round with an Aeration System to circulate the water, increase dissolved oxygen and keep oxygen levels more consistent throughout the pond. It will also keep a hole open in the ice, allowing for gas exchange.
  2. Muck Removal: Using natural bacteria, like MuckAway™, or a dredge in extreme cases, remove as much muck and decomposing debris as possible before the ice forms. This will prevent the pond from naturally filling in, and it will reduce the amount of gas produced from the decomposition process.

Winterkill is a disappointment, but it can be prevented with some planning and preparation in the fall. In the meantime, restock your pond and enjoy!

Why is my pond cloudy in the summer and clear in the winter? | Ponds & Lakes Q&A

Q: Why is my pond cloudy in the summer and clear in the winter?

Q: Why is my pond cloudy in the summer and clear in the winter?

Mike – Baldwin, WI

A: Frustrating, isn’t it? During the summer when it’s warm and inviting outside by the pond, the water looks cloudy; when it’s too cold to enjoy the outdoor scenery, the water appears crystal clear. What’s the deal? Let’s look below the water’s surface to see what happens during the two seasons.

Murky Summer

A lot happens in your pond during the warmer months. Fish are actively feeding and creating waste. Pond critters, like turtles and frogs, are digging around in the mud and stirring up muck at the bottom of the pond. Rainstorms wash sediment into the pond along with fertilizer residue – which provides fuel to algae and pond weeds growing prolifically in the summer sun. With all that activity, it’s no wonder the water looks cloudy!

Clear Winter

During the winter, however, activity slows. As your fishes’ metabolism decreases, they fast and hibernate through the cold season. Turtles, frogs and other pond residents reduce their movement, too, which allows the muck and sediment to settle at the bottom. Ice and snow cover the pond, limiting water movement and blocking sunlight. Algae still grows, but at a much slower rate. As everything settles and slows down, the water clears.

Extending Winter

If you want that crystal clear water all year long, follow this three-step formula, particularly as the days get longer and spring warmth thaws the ice:

  1. Feed Your Bacteria: First, be sure to add some bacteria enhancer, like EcoBoost™, to the water. It binds suspended organics, provides trace minerals to fish and other pond dwellers, and helps break down fertilizers from rain runoff. It has no temperature restrictions, so you can use it throughout the seasons.
  2. Shield the Sun’s Rays: Next, pour some Pond Dye in the water. The color reduces the amount of rays that into the pond. Like EcoBoost, Pond Dye has no temperature restrictions, so you can use it throughout the season.
  3. Add Oxygen: Aeration is the final – and most important – step in maintaining clean, clear water. By aerating your pond from the bottom up, you will circulate the water, improve the dissolved oxygen levels in your water column, and allow for increased levels of beneficial bacteria to accumulate in your pond.

I occasionally have power outages during the snowfall. Will it cause a problem for my aeration system? | Ponds & Lakes Q&A

Q: I occasionally have power outages during the snowfall. Will it cause a problem for my aeration system?

Q: I occasionally have power outages during the snowfall. Will it cause a problem for my aeration system?

Pete – Traverse City, MI

A: Power outages during heavy snowfall or ice storms aren’t uncommon – and when they happen, your aeration system will need some attention. Here’s what we recommend to prevent problems from occurring:

  1. Relieve Air Pressure: Built-up air pressure in the air compressor could potentially stop the aerator from turning back on when the power is restored, so it’s important to get rid of that pressure via the release valve.
  2. Check for Moisture, Condensation: If the power is out for an extended period of time, keep an eye on the cabinet for moisture and condensation. It could indicate reduced air flow, and all that wetness could freeze if temperatures are low enough.
  3. Clear Off Snow: To allow for proper air flow and to minimize moisture from melting snow around the unit, shovel or dust accumulating snow from around the cabinet.
  4. Melt Ice Blockages: Long power outages could cause your diffuser’s air lines to freeze. To melt them and open the air flow back up, pour 1 cup of isopropyl alcohol through each line (or the line you believe is blocked or frozen).

As for your fish, they should be just fine if your aerator shuts down for a few hours. Cold water holds more oxygen than warm water, so they’ll have plenty of oxygen during short-term interruptions.

I think my pond is spring-fed. If I shut down my aeration system, will the pond freeze enough for me to skate? | Ponds & Lakes Q&A

Q: I think my pond is spring-fed. If I shut down my aeration system, will the pond freeze enough for me to skate?

Q: I think my pond is spring-fed. If I shut down my aeration system, will the pond freeze enough for me to skate?

Timothy – Newton, WI

A: Skating is a winter favorite for many people – and it’s even better when you’re doing it on your own pond or lake. Before we dive into answering your question, however, let’s go through the differences between a spring-fed pond and a catch basin pond.

Catch Basin or Spring Fed?

A catch basin pond is a reservoir filled with precipitation runoff from the surrounding area. The volume rises and falls depending on rainfall and snow melt; in the winter, when conditions are right and temperatures are below freezing, an unaerated pond like this makes a great skating rink.

A spring-fed pond, however, is fed by a spring or ground water. It keeps the pond’s water level fairly consistent, regardless of rainfall, but the moving water created by the spring could cause dangerous conditions – even if the aeration system is shut down for the season.

Stay Safe on the Ice

If you discover your pond is indeed fed by a spring and has constant water movement, follow these Ice Safety Tips before trying to use the ice rink for recreation:

  • Wait for Extended Cold Temps: Spring-fed ponds will take longer to freeze, so be sure temperatures are below freezing for two to three weeks before testing the ice formation. Remember that wind and snow coverage will also affect ice formation and its integrity.
  • Test Ice Thickness: Once you’ve given the water time to freeze and the ice time to form, the next step is to verify the ice sheet’s thickness. You can either drill or cut samples—but make sure you do so in multiple locations as you work your way toward the center of the pond as the water won’t necessarily freeze evenly.
  • Stay Far from Moving Water: Water current and movement will also affect ice formation, so steer clear from any inflow and overflow areas where water movement will weaken the ice.
  • Shut Off Aeration: Of course, plan to turn off your aeration system before the ice starts forming on your pond. The aerator will agitate the water, preventing it from forming into a solid, safe sheet of ice.
  • Be Prepared: In case someone accidentally falls through the ice, don’t venture out on your own, and always make sure you have a life ring or floatation device within reach.

Winter recreation – skating, hockey, ice fishing and more! – is one of the joys of owning your own pond or lake, but always use common sense when venturing out. It’s better to be safe than sorry!

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!
