How Do I Tell Chara & Naiad Apart? | Ponds & Lakes Q&A

How Do I Tell Chara & Naiad Apart?

Thomas – Williamston, MI

It’s very important to be able to tell Chara and Naiad apart. Why? Because Chara is actually a form of algae and you must use an algaecide, like Algae Defense or Cutrine®-Plus, to treat it. Naiad, which looks similar to Chara, is an aquatic weed and you should use an herbicide, like Pond Logic® PondWeed Defense®, to treat it.
A couple of things to look for to help you differentiate between the two pond nuisances:

• Chara lacks true leaves because it is algae. Instead, it has 6 to 16 leaf-like branchlets that grow in spirals (whorls) around the stem. These branchlets often have tiny, thorn-like projections.
• Naiad has dark-green to greenish-purple, ribbon-like leaves. Naiad leaves are arranged oppositely on the stem, or sometimes in whorls of 3.
• Chara has no defined root system
• Naiad has a well-established root system
• Chara gets a foul, musky, almost garlic-like odor late in the season

If you are still unsure what type of plant you are dealing with, consider applying Hydrothol 191. A granular algaecide/herbicide, Hydrotol 191 is proven to treat both algae AND aquatic weeds but carries a 25 day irrigation & 3 day fish consumption restriction.

How Do I Get Rid Of Phragmites? | Ponds & Lakes Q&A

How Do I Get Rid Of Phragmites?

Robert – Steamboat Springs, CO

Phragmites, also known as common reeds, are wetland grasses that can grow up to 15 feet in height. They quickly become a nuisance because they form dense patches that choke out native plant and wildlife species, block shoreline views, and reduce access for swimming and fishing.

Completely eliminating phragmites takes several treatments. The majority of the plant is an extensive underground root system that is very difficult to fully eliminate. You can control the density and spread of phragmites with regular chemical treatments applied with a pressurized pond sprayer. Consider using an herbicide such as Kraken, which carries no restrictions on recreational use or livestock consumption of water from the treatment area.

Once phragmites have died, you should cut or burn the dead vegetation. The best time to treat phragmites is the summer when the plant is actively growing and seeding.

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?

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 50° 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 50° 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™ Pond Deskuzzer. 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?

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/Weed Cutter Combo 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 Avocet PLX 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/Weed Cutter Combo to remove the dead plants and prevent their potential to spread.

While Avocet PLX 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 50 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. Pond Logic Algae Defense Algaecide with Cide-Kick™ 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 Cide-Kick, 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 Applied Biochemists Cutrine®-Plus Granular Algaecide. 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 Aquatic Weed Cutter, raking with our Aquatic Weed 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.

I’m going to use my pond for skating over the winter. What do I need to do to store my aeration system?
Wayne – Pontiac, MI

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® Silent Black Air Filter, and install new Airmax® Silent Air 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.
