After a really warm day, I have algae floating on my pond. How do I control it? | Ponds & Lakes Q&A

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.

Are there different steps for treating a pondless waterfall versus a pond? | Decorative Ponds & Water Gardens Q & A

Q: Are there different steps for treating a pondless waterfall versus a pond?

A: Easy care is one of the most attractive features of a pondless waterfall, particularly for those who have a penchant for ponds but no time to perform routine maintenance on them. You get all the benefits of a water feature—the sound of running water, the added aesthetics in your garden space, even the plants and wildlife that it attracts—but you don’t have to deal with those pesky seasonal chores.

As ideal as they are, pondless water features do require some attention. Here are three simple steps to keep your waterfall looking its best:

1. Keep Your Water Clean and Clear

With no body of water, your pondless feature may not require you to remove muck, fish waste, decomposing leaves or other collected pollutants, but you still should keep the water looking clean and clear. Plan to periodically add some beneficial bacteria, like those found in Liquid Clear™, to gobble through any fine debris that may discolor your water or feed algae blooms.

2. Remove Buildup from Your Rocks

Rocks and other surfaces in your pondless waterfall will no doubt become breeding grounds for string algae and other debris, so take time to remove any buildup with an algaecide, like Algae-Off® String Algae Remover or Oxy-Lift™ Defense®. These fast-acting solutions use the power of oxygen to lift and wash away accumulated algae and muck. For best results, plan to turn off your system’s pump to ensure the powder contacts every surface, restarting it after the product has time to work.

3. Check Your Water Levels

Because the water basin is hidden, you can’t always see how much water there actually is in your pondless waterfall. To prevent your pump from drying up, make sure you periodically check the reservoir — or, better yet, add an auto-fill valve, like the PondBuilder™ Automatic Water Fill Kit, that will refill any water lost to splashing or evaporation. It’s easy to install and can be adapted to any garden hose, ½-inch irrigation line or vinyl tubing.

If things have really headed south, try performing a partial or complete water change along with using some beneficial bacteria. They will get you—and your pondless waterfall—back on track and ready for summer enjoyment.
