A: With summer temperatures settling in, algae blooms are coming out swinging. Bright sunshine and warm temperatures trigger green growth, so it’s critical to keep floating and submerged algae in check before it grows out of control.

For the health of your pond and its inhabitants, keeping algae blooms to a minimum is necessary. Here’s an approach that works to eliminate the green stuff and prevent it from taking over:

Treat the Growth
First, use an algaecide to great rid of the algae bloom. You can treat floating algae with a fast-acting liquid spray like Algae Defense® Algaecide with Treatment Booster™ PLUS, which treats floating algae and chara that’s less than 3’ deep. Simply spray it on with a pressurized sprayer to combat floating and bottom-growing algae.

Submerged algae can be treated with sinking granular products, such as Cutrine®-Plus. It works well for algae submerged deep in your pond or lake, such as Chara. It’s best distributed on a calm day via a granular spreader in the morning before mats form.

Remove the Dead Algae
Once the algae is dead, you should remove it. Why? By leaving the dead foliage in the lake, it will start to break down and become nutrients—or algae food—for new blooms. It’s a vicious cycle!

Use a pond skimmer, like the PondSkim™, or a rake, like the Pond & Beach Rake, to prevent that muck from accumulating.

Add Beneficial Bacteria
Three days after you’ve used algaecides, treat your pond with PondClear™. It contains beneficial bacteria that gobbles through the organic material that’s suspended in the water column. The result is a lake filled with clean, clear, odor-free water—and a healthy ecosystem for your game fish and other pond inhabitants.

Shade Water with Pond Dye
Finally, be sure to add blue or black pond dye to your pond throughout the spring and summer. By reducing the amount of sunlight that shines through the water and stimulates plant growth, you will ultimately reduce the amount of algae.

A: Inside your ClearPAC® PLUS box, you’ll find everything you need to keep your lake clean and clear this spring and summer. The five components, when used as directed, address the root of the most common pond problems by tackling excess nutrients and shielding the water from algae-feeding sunlight.
When should you start using ClearPAC® PLUS? It all depends on your water temperature. Let’s take a closer look at when and how to best use the products in your super-pack.

  • Pond Dye: As soon as the ice melts on your pond or lake, add your Nature’s Blue™ Pond Dye. The dye is not temperature-sensitive so it can be used even when water temps are too cold for beneficial bacteria products. Pond Dye does more than color your water and add to your landscape’s aesthetic; it also shades it from sunlight, which can kick-start algae blooms as the mercury rises.
  • PondClear™ and MuckAway™: When water temperatures rise to a consistent 50°F, you can start using the beneficial bacteria found in PondClear™ and MuckAway™ to break down nutrients suspended in your water column and muck on the bottom of your pond. These products can be used at the same time as your Pond Dye and EcoBoost™.
  • EcoBoost™: This bacteria booster that has no temperature restrictions, so it can be used year-round to bind phosphates that find their way into your pond or lake. You can use EcoBoost™ throughout the spring to give you a head start on pond season.
  • Algae Defense® : To be used only as needed, this algae-destroyer treats troublesome floating filamentous algae, bottom growing chara and the planktonic algae when it’s green and growing. Use Algae Defense® when the water temperature in your pond or lake is above 60°F. Don’t use Algae Defense® if you keep koi or trout in your lake.

After treating your pond with ClearPAC® PLUS, don’t forget to remove dead algae and debris with your Pond & Beach Rake. Doing so will remove the decaying vegetation and prevent them from feeding the algae—which will ultimately help your Pond Dye, PondClear™, MuckAway™, EcoBoost™ and Algae Defense® work even better!

I don’t know if I have chara or another weed. How do I tell? | Ponds & Lakes Q&A

Dan – W Jefferson, OH

A: Though it resembles a pond weed, chara—also called muskgrass or skunkweed—is actually a type of bottom-growing algae that can efficiently take over your pond or lake.

Can’t tell the difference between the two? Here are some tips to help identify and treat the chara.

IDing Chara

Pull out some of the plant in question and take a close look at it. Does it have these characteristics?

  • No Roots: Unlike pond weeds with traditional leaves and well-established root systems, chara is a gray-green branched multicellular algae that lacks flowers, true leaves and roots. Instead, it has six to 16 leaf-like branchlets that grow in spirals around the stem.
  • Distinct Odor: Next, smell it. Does it have a skunky, musty, garlicky-type smell? If so, it’s probably chara. Simply walking close to or around your pond will tell you right away if you have a chara problem, particularly late in the pond season.
  • Crunchy Texture: When you rub the plant between your fingers, what does it feel like? Chara has a crunchy or gritty-type texture that’s different than pond weeds.
  • Quickly Disintegrates: Finally, when you leave it on the dock, what happens to it after a few hours? If it almost disintegrates after a few hours, you’ve got chara.

Treating Chara

Once you determine it’s chara and not a pond weed, you’ll need to treat it with an algaecide rather than an herbicide. We prefer to use Pond Logic® Algae Defense® Algaecide, a fast-acting liquid formula, but use Cutrine®-Plus Granular as for chara growing in water deeper than 3 feet.

About two weeks after treating the chara, we suggest to use a Pond Rake to rake out as much as you can Doing this will help you gain control relatively quickly. (Important tip: Do not rake out chara before treating it because it will spread).

Jeremy – Clinton, IA

A: It sure doesn’t take much for algae to grow out of control! Combine warm sunshine with some algae-loving nutrients and, before long, you’ll have a pond full of pea soup. When it’s thick and dense, those tiny plants can then suck all the oxygen from the water, leaving your fish gasping for air. Plus, it looks bad and can cause some major stink.

For the health of your fish and your lake, you must regain control. Here’s a two-pronged approach that works to eliminate the green stuff and prevent it from taking over.

TREAT THE GROWTH

First, you need to get rid of the algae blooms. For floating algae and chara that’s less than 3 feet deep, use Algae Defense®. The aquatic algaecide comes in a fast-acting liquid formula that can be directly applied to your lake with a pressurized sprayer. If you’re dealing with chara that’s deeper than 3 feet, use Cutrine®-Plus. Its granular formula sinks to the bottom of your lake and destroys the algae.

Once the algaecides start working to kill the blooms, don’t forget to remove dead algae from the pond with a tool like the Pond Rake. If you leave the dead foliage in the lake, will start to break down and become nutrients—or algae food—for new blooms. It’s a vicious cycle!

TREAT THE SOURCE

Now that you’ve got the algae under control, it’s time to get proactive and prevent its future growth. Begin by adding PondClear™ & MuckAway™. These products contain beneficial bacteria that gobble through excess nutrients like suspended organic waste and muck in your pond. The result: Clean and clear water with no noxious odors.

Next, shade the water with pond dye. By preventing the sun’s rays from penetrating the water, you’ll starve the algae of sunlight, which it needs to thrive.

Q: When can I start treating the floating algae in my pond?

Alex – East Earl, PA

A: The magic number you’re looking for is 60—a water temperature of 60° Fahrenheit, that is. Chemicals that treat algae aren’t very effective at temperatures below that, and so the time to start attacking the green growth is when your underwater thermometer reads higher than 60°.

Once your lake water is warm enough, you can start treating floating algae with a chemical of choice depending on your pond’s situation:

  • If You Have Submerged Algae: Granular products, such as Applied Biochemists Cutrine®-Plus Granular Algaecide, work well for algae submerged deep in your pond or lake, such as Chara. It’s best distributed on a calm day via a granular spreader in the morning before mats form.
  • If You Have Surface or Perimeter Algae: Fast-acting liquid spray, such as Pond Logic® Algae Defense® Algaecide with Treatment Booster™ PLUS, effectively treats algae floating around the perimeter of your pond. Simply spray it on with a pressurized sprayer to combat floating and bottom-growing algae.

Once the algae is dead, remove it as soon as possible with a pond skimmer, such as The Pond Guy® PondSkim™ Debris Skimmer, or a lake rake, like the Pond & Beach Rake. By removing the dead growth, you prevent the organic muck material from accumulating along the pond bottom and feeding future algae blooms throughout the season.

If water temps are below 60, practice some patience. You’ll have to wait until your lake’s water warms before you can battle the green menace with chemicals. If your algae situation is already excessive, however, get out your Rake and start removing some of those mats until you can nuke them with chemicals.

Q: Is it too cold to treat my algae blooms?

Ashley – Cross Junction, VA

A: The bane of pond keepers, algae—be it planktonic pea soup, filamentous pond scum or bottom-dwelling chara—can be treated any time of year, as long as the water temperature in your pond or lake is above 60 degrees Fahrenheit.

But what’s so special about the magical 60-degree temp?

Though algae will grow at temperatures lower than that, the chemicals in both Pond Logic® Algae Defense & Treatment Booster™ PLUS Combo and Applied Biochemists Cutrine®-Plus Granular Algaecide that are used to control suspended, floating and bottom-of-the-pond algae require warmer water temperatures to work properly.

If you’re unsure of your lake’s water temperature, use a pond thermometer, like the Pond Logic® Floating Pond Thermometer, to get a fast and accurate reading.

Here are three more tips for treating fall algae blooms:

1. Heavier doses may be required: When treating well-established algae or algae that has grown later in the season, you may need to up your dosage rates to get the same effect as when treating fresh algae or algae that has sprung up in the spring. Read the product’s label for safe usage guidelines.

2. Use the right product: Pond Logic® Algae Defense & Treatment Booster™ PLUS Combo will take a serious toll on planktonic, filamentous and chara growth, but Applied Biochemists Cutrine®-Plus Granular Algaecide works especially well on chara. Well-established chara will build up a chalky deposit, which gives it super powers against chemical treatments. But the Cutrine®-Plus granules sink to the bottom of the pond and dissipate right where that nuisance algae resides.

3. Watch the weather: The best time to apply Algae Defense® and Cutrine®-Plus Granular is in the morning on a calm, sunny day. For the Algae Defense®, simply mix with water and spray with a pressurized sprayer; for the Cutrine®-Plus Granular, broadcast the granules in the area that needs to be treated.

Once the water temperature dips below 60 degrees Fahrenheit, you’re out of luck when it comes to treating algae blooms. But you can revel in the fact that they will slow down when the water reaches 50 degrees or so—only to emerge again come spring!

Q: Why can’t I treat my pond with the common weed killer I use around my yard?

Duane – Spring Grove, PA

A: It may seem like a convenience and a cost savings to use your terrestrial weed herbicides to treat weeds in your pond or lake. But when it comes to managing nuisance growth in and around your pond, not all chemicals are created equally.

Though broad-spectrum-use herbicides like diuron work great on grassy terrestrial weeds, they’re not approved for use on cattails and water milfoil because of the direct contact with public waterways or possibility of leaching into drinking/ground water. Instead, you need to use products that are registered by the Environmental Protection Agency for aquatic use, like Algae Defense®, Aquathol® and Shoreline Defense® aquatic herbicides.

Why the regulations? Read on for details.

Environmental Protection

The EPA registers products like herbicides for aquatic use to protect the environment. Its goal is to minimize harm while maximizing results.

The government agency tests the ingredients’ concentration, frequency of use and effectiveness for their short-term and long-term effects in their intended environment. It also checks the chemicals’ half life, which is how long the substances remain in the environment before breaking down enough to be considered non-toxic.

Safer for Your Pond Visitors

If you use unapproved chemicals in your pond or lake, you could be doing harm to not only the ecosystem but also to your fish, your livestock and wildlife, your soil and, most importantly, to yourself, your family and your neighbors.

Herbicides that have been approved by the EPA include specific restrictions and precautions on their labels about consuming fish after treating bodies of water. They caution against swimming in or drinking from treated ponds within a certain amount of time after application. They even warn of soil contamination issues that landowners or pond professionals should be aware of.

Chemicals that are not approved for aquatic use have none of these warnings because they have not been tested for their effects on the pond habitat. In fact, some products can actually be considered a contaminant to the aquatic environment – and you don’t want that, right?

Obey the EPA

Even if you don’t consume your game fish, swim in your lake or drink the water, you should steer clear of unapproved chemicals. Some of them can leach into the soil surrounding the pond or be released during heavy rains when ponds flood. That runoff – including the potentially toxic chemicals – can then be released into the public waterways or wetlands used by neighbors.

Play it safe. Obey the EPA.
