Will Algaecides & Herbicides Harm My Beneficial Bacteria? | Ponds & Lakes Q&A

Will Algaecides & Herbicides Harm My Beneficial Bacteria?

Kenneth – Lawton, OK

Some chemical treatments can affect the performance of your beneficial bacteria. It’s best to wait 72 hours after a chemical treatment to add bacteria. Certain chemical treatments contain copper, and copper can reduce the effectiveness of bacteria. If you wait a few days, you’ll ensure no loss of bacteria from a chemical interaction and the bacteria will have a lot of newly killed weeds to feed on. If you can’t wait, apply bacteria away from the treated areas of your pond. For example, if you put chemicals around the edge of your pond, add bacteria such Pond Logic® PondClear™, to the center. This will prevent the chance of overlapping chemicals with natural bacteria.

When Should I Start Treating Floating Algae In My Pond? | Ponds & Lakes Q&A

When Should I Start Treating Floating Algae In My Pond?

Jacquelyn – Pottsville, PA

 

Spring is just around the corner and in some areas, algae is already growing. But the question we hear quite often around this time is, “When can I start?” or, “Is it too early to treat?” The answer really depends on what the weather is like at your pond.

Getting a jump start on algae early in the season can help control growth as the season progresses. Fortunately, treating floating algae and preventing its build up is rather easy and really only one factor may stop you…temperature.

Is your pond above or below 50 degrees? This is important because aquatic algicides become less effective when temperatures fall below 60° Fahrenheit. However, understand that treatments will still work, just not as well. If you have an abundance of algae growing when the water temperatures are below 60° Fahrenheit, it’s worth a quick treatment to get it under control early. If the water temperature is too low, wait to use any treatment and instead use a lake rake to remove excessive algae if you are not able to chemically treat it. Another up-and-coming product that works very well to skim floating debris is the PondSkim™ Debris Skimmer. The PondSkim™ is a tool that contains a float and debris catcher. Simply drag across the surface of the water to collect debris.

If you have algae already growing in your pond we suggest that you get a jump start on it and you’ll be happy you did.

Do Cattails actually die in the winter or can I do something to prevent them from coming back? | Pond & Lake Q&A

Do Cattails actually die in the winter or can I do something to prevent them from coming back?

Brian – Holland, MI

As grandfather used to say, “never trust a sleeping cattail.” Actually, grandfather never said that. But he should have – because it’s true.

During the winter months, cattail foliage dies off. Leaves and stems turn brown and dry up when the weather gets cold, and optimistic pond keepers dare to imagine their backyard water features without the scourge of unwanted cattails. But deep beneath the pond, cattail roots are alive and well in their dormant state, saving up their energy to come back strong in the spring.

Fortunately, cattails aren’t invincible. Depending on the season, enterprising pond owners can take steps to eliminate cattails, leaving their backyard water features in great shape to host more desirable aquatic plants and fish.

When winter rolls around, and cattails have dried up, it’s worthwhile to cut the dead foliage and remove it. Our Pond Rake and Weed Cutter is specifically designed to make this process quick and easy. While this won’t kill the cattails, it will lay the groundwork for a successful spring offensive.

In spring, summer and fall, when cattail foliage is thriving, it’s time to apply our Shoreline Defense® Aquatic Herbicide. This safe, powerful herbicide is applied directly to all above-water cattail foliage. Once applied, the herbicide attacks and kills the entire plant – including its root system. Once the plant is dead, you’ll want to resume the use of your Pond Rake and Weed Cutter to remove the dead plants and prevent their potential to spread.

While Shoreline Defense® is effective on spring growth, it’s most effective during late summer and fall, when foliage is at its peak.

Is there an ideal temperature to treat algae? | Pond & Lake Q&A

Is there an ideal temperature to treat algae?

Is there an ideal temperature to treat algae?

Crystal – New Baltimore, MI

It depends what you mean by the word “treat.” If you’re looking to throw a party in its honor, pretty much any temperature will do – because algae grows all year ‘round, even during the winter months. But if you’re hoping to give it the kind of treatment that makes it feel extremely unwelcome, you’ll see the best results when water temperatures are at 60 degrees Fahrenheit or higher. When water is warmer, algae tends to thrive. Because it’s thriving, it’s feeding – making it much more susceptible to algaecides.

Because very few of our customers express interest in enhancing algae growth, we’ll assume most readers are in the latter category. And if you are, we have a variety of highly effective options to accomplish your objectives. Algae Defense® with Treatment Booster™ PLUS is among our safest, most effective weapons in the battle against algae. Algae Defense® is a fast-acting aquatic algaecide, and it’s highly effective at eliminating a broad spectrum of pond algae. By including Treatment Booster™ PLUS, which breaks down algae’s natural defenses, this combination packs a particularly effective double-whammy, and makes short work of offending algae blooms.

For spot-treatment of algae growth, we also recommend Cutrine®-Plus Granular . Formulated to make quick work of both surface and bottom-forming algae, this safe, powerful algaecide does double-duty by both killing existing algae, and inhibiting its future growth.

While some pond owners prefer to eschew algaecide and rake algae out manually, the raking-only approach requires much more maintenance and attention. Algae are extremely hearty, and raking leaves trace amounts in the pond, allowing for recurrent blooms. For longer-lasting impact, the ideal treatment includes the use of algaecides, followed by cutting with our weed cutter, raking with our Pond & Beach Rake, and follow-up treatment with natural bacteria to break down any remaining muck.

Give your algae the treatment they deserve before temperatures start to fall – and start next season with a leg up on their plans for next year’s invasion.

One of the great joys of a backyard pond is its four-season versatility. After three seasons of aesthetic satisfaction, there’s nothing better than strapping on a pair of skates and hitting the water when it hardens up for the winter. But before the temperatures drop, your aeration system demands some seasonal attention.

As a rule, it’s okay to keep your aeration system in operation until ice begins to form. When that day arrives, it’s time to shut the aerator off. At that point, you’ll want to put the compressor and its housing in a cool, dry place to avoid exposure to the elements, where dramatic weather changes can cause condensation that may cause damage. To accomplish this step, first disconnect the compressor from the airline. Be sure to cap the exposed end of the airline, leaving the remaining line buried, and diffuser plates in the pond.

When the aeration season is over, it’s a great time to perform regular maintenance. Consider changing your air filter. Choose a high quality replacement, like our Airmax® SilentAir™ Complete Filter Assembly, and install new Airmax® SilentAir™ Replacement Air Filter Elements if your filter is in good enough shape for another season.

If you’ve noticed that your compressor is producing less air than it should, you may want to consider the use of a Maintenance Kit to boost the compressors performance or inspect the diffusers and replace any damaged diffuser membranes. If you’re still using air stones, it’s the perfect time to upgrade to Airmax® Membrane Diffuser Sticks, which are easy to install, and virtually maintenance free.

Happy skating.

It’s been cold where I live. Should I stop with my bacteria now? | Pond & Lakes Q&A

In bacteria paradise, the temperature in your backyard pond would never fall below 50 degrees Fahrenheit. When water temperatures drop below 50 for any sustained period of time, the bacteria call it quits for the season.

But just because you’ve been feeling the cold for a few days, remember: it takes water longer to respond to changing temperatures. Thus, when it’s below 50 degrees outside for a lengthy stretch, your pond water may not have fallen as far – and your bacteria may be doing just fine. To get the most accurate reading you can, consider buying our Pond Logic® Floating Pond Thermometer. It’ll give you up-to-the minute readings, making it easy to monitor the health of – and the need for – your favorite bacteria.

When your pond is still in the above-50 degree range, we strongly recommend the continued use of Pond Logic® PondClear™ Beneficial Bacteria, and Pond Logic® MuckAway™ Pond Muck Reducer. These two products help to maintain healthy bacteria levels in your pond, which will help to reduce organics, excess nutrients and noxious odors, while breaking down muck and keeping your pond water clear.

Once your pond water drops below 50 degrees, you can safely suspend bacteria treatments. But when the temperatures start to rise again in the spring, be prepared to start back up – and get your pond water in great shape for another season.

Kevin – Boise, ID

At first blush, it seems pretty logical to cut cattails before treating them. But when you understand how the treatment works, it’s immediately clear: cutting first is the wrong way to go.

Here at The Pond Guy®, we’re big fans of Shoreline Defense® Aquatic Herbicide. When it comes to eradicating cattails and other grassy plants, nothing does a better job. Shoreline Defense® works best when use with a powerful surfactant that breaks down the waxy cuticle of the plant, allowing the herbicide to penetrate the stalks of cattails. The cattails then do the rest of the work, carrying the chemical treatment throughout the root system to kill the plant at its source.

Because cattails only use a small portion of their root system at one time, a single application of Shoreline Defense® should be allowed to work for a week or two before cutting the plants down with our Jenlis Weed Razer™ or Jenlis Weed Razer™ Pro Aquatic Weed Cutter. Occasionally, some roots will survive and send up new growth. When that happens, simply reapply Shoreline Defense®, wait an additional week or two, and repeat the process.

So, while it might be tempting to take out your frustrations and cut down offending cattails to remove the blight before treatment, take your time. The results will be worth the wait.
