Q: After a really warm day, I have algae floating on my pond. How do I control it?

Steve – Grand Rapids, MI

A: Plants in your vegetable garden love the warm sunshine—and so do the plants in your pond or lake, including algae. Warm temperatures and bright sunshine trigger green growth, so it’s critical to keep floating and submerged algae under control before it grows out of control.

Here’s what we recommend:

1. Treat the Growth

First, use an algaecide to kill the green stuff. You can treat floating algae with a fast-acting liquid spray like Pond Logic® Algae Defense® Algaecide with Treatment Booster™ PLUS, which treats algae floating around the perimeter of your pond. 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 Granular Algaecide. 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.

2. Remove the Dead Algae

Once the algae is dead, you should remove it. Why? Because that decomposing foliage turns into pond muck, which feeds future algae blooms throughout the season. Use a pond skimmer, like The Pond Guy® PondSkim™ Debris Skimmer, or a lake rake, like Pond Logic® Pond & Beach Rake, to prevent that muck from accumulating.

3. 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.

4. Shade Water with Pond Dye

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

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.

ONE-STOP SHOPPING

Looking for an easy solution? Check out the ClearPAC® PLUS. This all-in-one algae destroyer contains everything you’ll need to kill the algae and prevent future growth. It contains algaecide, beneficial bacteria and pond dye to fight algae and suspended debris all season long.

Do You Know Who You Are Dealing With?

When faced with an outbreak of weeds in their pond some pond owners tend to rush into buying aquatic herbicides and algaecides in an attempt to clear up the pond as fast as possible. While we agree with the idea that your weeds need to disappear on the double, you want to make sure you take some time out to identify your intruder. When you know what you are dealing with your can then chose a product to treat it that will give you the best bang for your buck. If you are having trouble identifying a particular weed you can e-mail a couple close up pictures to The Pond Guy at mrwig@thepondguy.com or check out our Weed ID Guide.

What’s The Difference?

Knowing is half the battle in your war against aquatic weeds. So what do you need to know about Naiad to correctly identify it in a line-up of other unruly pond perpetrators? Naiad is an annual plant that branches profusely and forms very dense stands of rooted submerged vegetation. Leaves are dark green to greenish-purple, ribbon-like, opposite or in a whorl of three, mostly less than 1/2 inch long and 1/8 inch wide. Single seeds are found encased in the leaf sheath. Southern naiad reproduces by seeds and fragmentation. Flowers are at the base of the leaves but so small that they can only be observed with magnification. While Naiad is often confused with Chara at first glance, Chara has a strong, unpleasant odor and a crunchy texture that sets it apart from its counterpart. Chara also is very easy to pull out since it has no attached root base.

Pick Your Pony

You will find a stable full of products available for treating Naiad each with their own application methods and water use restrictions. Hydrothol 191 for example is a granular that sinks to the bottom of the pond and is applied with a hand spreader. It carries water use restrictions such as a 3 day fish consumption restriction and a 25 day irrigation restriction. Pondweed Defense on the other hand is a liquid aquatic herbicide that is applied via a Tank Sprayer and carries no water use restrictions. Read each herbicides application instructions, water use restrictions and dosage rates to determine which product is best for you. In addition to Hydrothol and Pondweed Defense, WhiteCap and RedWing are also viable options for treating Naiad.

Revenge Is A Dish Best Served Warm

For optimal results you will want to treat your pond when your water temps are above 50 degrees. Waiting for warmer weather in late Spring and early Summer ensures that the weeds in your pond are actively growing and will eagerly take the chemical you add to the water. Once the weeds are killed it is then safe for you to rake them out of the pond using a Pond & Beach Rake or something similar. Keeping your ponds nutrient load in check with MuckAway and PondClear and proper Aeration will make sure you spend less time wrestling weeds in your pond and more time enjoying your ponding season.
