How are algae able to grow in the winter when everything else is dormant? | Ponds & Lakes Q&A

Q: How are algae able to grow in the winter when everything else is dormant?

Q: How are algae able to grow in the winter when everything else is dormant?

Patrick – Vandalia, IL

A: Algae can be tough little buggers. An estimated 72,500 algal species exist worldwide, and some of them can thrive in inhospitable conditions, including areas with ice and snow. With a handful of nutrients and a little bit of light, they’re able to grow – even in the 39 degree water under the ice in your lake.

But if your lake’s water is clean and clear during the spring and summer, how can it explode with algae in the winter?

Food Aplenty

Algae feed on byproducts of decomposing organic debris, like phosphorous and nitrogen, in the water. During the warmer months, natural bacteria would typically break down these nutrients, leaving little food for the organisms. But in the cooler months, those bacteria go dormant. That means the algae enjoy a feast – and a population explosion.

If you keep a hole in your lake’s ice, you can help control the nutrient density with a product like Pond Logic® EcoBoost™. This bacteria enhancer, which has no temperature restrictions, binds suspended organics while providing trace minerals to fish. Simply mix it with water and pour it into the lake.

Let There Be Light

Algae also require sunlight to thrive – but not much. Even through a clear, solid sheet of ice, algae can get enough light to use for photosynthesis. When that light is impeded, however, the algae won’t grow as quickly.

A layer of thick snow cover is Mother Nature’s way of preventing light from penetrating the water, but you can also use pond dye, to block those rays. Pond dye is available as a liquid or in water-soluble packets that you can toss into your pond.

Algae’s Benefits

Believe it or not, algae growth in the winter does have its benefits. It helps to filter the water, and on warmer days it’s a great snack for your fish. Plus, when the algae photosynthesize, they give off oxygen as a byproduct – which is then available for your fish (and other aquatic critters) to breathe.

Don’t worry: The algae won’t take over your pond like it does in the summer. It can grow, but the cold temperatures aren’t ideal for explosive outbreaks.

We just purchased a house and it has a backyard swimming pond. How do we measure it? | Ponds & Lakes Q&A

Rob – Hawthorne, FL

A: Surface area and pond depth are important measurements to know. They’ll help you determine dosage rates with chemicals like algaecide. They’ll help you calculate the right-size aeration system for your pond. And they’ll help you figure out how many and what types of fish to stock.

Finding those magic numbers isn’t difficult – but it does require some tools, the right equation and a little bit of work. Before you head out to your pond, grab a rope marked at 1-foot increments, a weight that’s heavy enough to sink to the bottom, and something for notetaking.

Calculating Surface Area

The easiest ponds to measure are those that resemble a rectangle, but you can figure out the surface area of a circular, triangular or odd-shaped pond, too. First, you’ll need to measure (with your marked rope) or pace off (one step is about 3 feet) some specific distances, depending on the shape of your pond. Then, plug those numbers into one of these formulas:

  • Square/rectangle: Calculate length and width; L x W = Surface Area
  • Circle: Calculate radius; Pi x R2 , or 3.14 x R x R = Surface Area
  • Triangle: Calculate base and height; (0.5 x B) x H = Surface Area
  • Odd-shaped: Use a handy online tool like Bing Maps to measure the pond. Online tools may be easiest, especially for irregularly shaped ponds.

To determine how many acres your pond is, you’ll then divide that surface area figure by 43,560 (one acre).

Calculating Depth

Figuring out your pond’s depth is a bit trickier, particularly if you have plant shelves or if the pond has a slope. Grab your marked string, the weight, something to write with, and a boat or canoe. Then, head out to the pond and follow these directions:

  1. Securely attach the weight to one end of your string.
  2. Climb aboard your boat or canoe with your weighted string and note-taking materials in hand.
  3. Travel to at least five points in various areas your pond, more if your pond is particularly large.
  4. Drop the weight into the water and note where you feel it hit the bottom. Repeat until you’ve gone to all the different spots and gathered a good sampling of your pond’s depth.

If math isn’t one of your favorite subjects, just take your measurements and plug them into our pond calculator. Simply select your pond type and shape, enter your measurements and let the calculator do the math!

Why They’re Important

Now that you know your pond’s size, why are those calculations important?

You’ll need the numbers to determine dosage rates on chemical products like those found in Pond Logic® ClearPAC® PLUS. If the pond has been around more than three to five years, chances are good that you’ll need to address problems like muck accumulation and string algae growth in the spring.

Those numbers will also help you select the right-size Aquastream™ Fountain and Airmax® Aeration System. For instance, if your pond is less than 6 feet deep, the Shallow Water Series™ Aeration System is a good choice; if your pond is greater than 6 feet deep, the Shallow Water HP Series™ or PondSeries™ Aeration System is the one for you.

Since you’ll be able to calculate how many acres your pond is, you’ll also be able to determine what types of fish you can have and how many of them you can keep. Finally, because you’ll know the various depths of your pond, you’ll be able to stake out safe swimming areas for children – but don’t forget to put out your life ring!

We had a couple of warm days. Is there anything I should be working on for the spring? | Ponds & Lakes Q&A

Scott – Eureka, IL

A: We may have another month or two of winter ahead of us, but that doesn’t mean you can’t head out to the pond on sunny days and get a jump-start on your spring cleaning and maintenance chores. Here are a few ideas:

  1. Tidy Things Up
    Rain, snow, wind and winter precipitation do a number on landscaping, so take some time to clean up the foliage around your pond. Remove fallen branches, rake leaves and debris, cut down cattails and pull out any pond weeds you can reach. Two great all-purpose tools to use for the task are the Weed Cutter and the  Pond & Beach Rake. The cutter slices through floating debris like aquatic vegetation, weeds, cattails and phragmites; the rake, which works on land and in the water, allows you to mechanically remove those cut weeds, algae, muck and debris.
  2. Inspect Mechanical Parts
    Sunshine is a perfect excuse to tinker with outside toys, like your aeration system. Head out to the pond and check your air filters. Do they need changing? How’s the airflow from the lines? Is it what you expect? Is your air compressor operating properly? If needed, install new air filters, clean out your lines, and tune up your air compressor with a maintenance kit. Keep your system performing optimally – even if it’s still winter.
  3. Add Pond Dye
    Pond Dye can be used all year long. Even though the sun isn’t as strong in the wintertime, some UVs still get through – and they can fuel algae blooms that could affect your water quality. Pond dye shades the water and prevents those blooms from happening.

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.

People ice fish on lakes, but can you ice fish on a small pond, too? | Ponds & Lakes Q&A

Q: People ice fish on lakes, but can you ice fish on a small pond, too?

Q: People ice fish on lakes, but can you ice fish on a small pond, too?

Ron – Galesville, WI

A: Absolutely! Ice fishing on a small pond can be just as rewarding as ice fishing on a lake – particularly if it’s stocked with bass, bluegill and perch. Here are five tips for making this wintertime sport safe and enjoyable.

  1. Partner Up: Whether you’re ice fishing on a huge lake or a small pond, always fish with a partner. Venturing out on the ice is never 100 percent safe, so have someone there to watch your back and lend a hand in case of emergency. Also be sure to have a Life Ring and first aid kit easily accessible. Better to be safe than sorry!
  2. Check Ice Thickness, Quality: Before heading out, check the thickness and quality of the ice. It should be at least 4 to 5 inches thick and ideally composed of solid, blue ice rather than white, brittle ice or ice with cracks or trapped air bubbles. Here’s a quick primer that explains how to check the integrity of your ice.
  3. Tackle Box Ready: Make sure you have the right equipment on hand, including small reels or ice rods, jigs and a variety of bait. In addition, pack your fish finder, auger and any other tools you’ll need to track down and hook those finned beauties.
  4. Location, Location, Location: When the hunt is on, find your fish with a fish finder or pick a deeper, sheltered area where fish would most likely be and drill a hole with an auger. To make this fish-finding task easier next year, consider positioning Fish Habitat in shallower areas of your pond. Logs and shrubs with flexible limbs create a perfect habitat for the fish – and a perfect spot for catching them.
  5. Timing is Everything: The best time to fish is early in the morning or late at night when the fish are out and about, searching for food. If you haven’t caught anything after 15 minutes, try a new hole or offer the fish a different type of bait.

Ice fishing on a smaller pond or lake is a great way to enjoy the great outdoors – even when the weather is less than ideal. Have fun, be safe and fish on!

Can I move my diffuser plates all to the shallow end of the pond so I can skate on the other side? | Ponds & Lakes Q&A

Q: Can I move my diffuser plates all to the shallow end of the pond so I can skate on the other side?

Q: Can I move my diffuser plates all to the shallow end of the pond so I can skate on the other side?

Adam – Locust Valley, NY

A: Though it would be nice to have the best of both worlds, a pond that’s aerated with diffuser plates is not safe for ice skating. Here’s why:

The reason you run a diffuser through the winter is to aerate the pond and move the water surface to maintain a hole in the ice, allowing for gas exchange. This ensures the water in your pond is well-circulated and your game fish and other underwater inhabitants have enough oxygen to get them through the cold season.

The trouble is that the ice that forms on the surface of water that has been moving for even a short time can be porous and not suitable for skating. Even movement on one end of the pond and not the other can make the ice at the edges unsafe.

If you want to use your pond for skating, plan in advance. Before the ice forms:

  1. 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 components away. Your airline and plate may stay in the pond, but the system’s cabinet and compressor should be stored indoors to prevent condensation and rusting.
  3. 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 Taylor Made Life Ring. If the ice breaks, a safety preserver like this can save someone’s life.

Even if ice skating isn’t your thing, it’s still important to follow this all-or-nothing aeration strategy. Running your system “part time” could cause condensation in the unit from the hot compressor cooling, causing rust to form. It could also allow moisture to get into the airline, which could then freeze.

Bottom line: If you plan on skating on your pond or running your aeration system “part time” for whatever reason, it’s best to shut it down completely. Otherwise, keep it running all season to ensure good water quality for your fishes.
