Algae can quickly take over a pond, turning the water green and murky. Not only is this unsightly, but it can also harm fish and other aquatic life. Fortunately, there are several effective methods for removing pond algae and keeping your water clear and healthy. Here are five options to consider.
The Frog’s Advice: Note, all ponds will experience some form of algae growth during natural seasonal transitions. When spring ends and the weather turns hotter for summer, a sudden bump in temperatures will cause what’s known as algae blooms. These blooms will be temporary while the season’s temperatures stabilize and as long as you’re using the method’s below for ongoing algae prevention.
1. Use a Pond Skimmer for Filtration.

One effective way to get rid of algae in your pond is to use a pond skimmer to remove debris. This tool works by skimming the surface of the water and collecting any leaves, twigs, or other organic matter that may be contributing to the growth of algae. By removing this debris, you can reduce the amount of nutrients in the water that algae need to thrive. Be sure to use the skimmer regularly to prevent buildup and keep your pond looking its best. We sell skimmers in various sizes such as Signature Series 200, 400, & 1000. Available at Pond Country retail stores.
2. Add Maintain or Beneficial Bacteria to Your Pond.

Maintain for Ponds combines highly effective pond water treatments into one powerful formula to successfully keep ponds clean, clear, healthy and maintenance-free. This easy-to-use water treatment contains a powerful blend of beneficial bacteria, phosphate binder, flocculent and pond detoxifier.
The bacteria blend includes lithotrophic, heterotrophic and photosynthetic bacteria strains, which keep pond water healthy, beautiful and safe for pond fish. The included phosphate binder locks up excess nutrients that could otherwise cause issues with water quality, and the flocculent quickly clears cloudy water by clumping suspended debris. A pond water detoxifier is added to the formula to remove and detoxify chlorine, chloramine, heavy-metals and other toxins, making your pond water safe for fish and plants. Maintain for Ponds is safe for fish, plants, pets, and wildlife. Available at Pond Country retail stores.
Another effective way to get rid of algae in your pond is to add beneficial bacteria. These bacteria work by breaking down organic matter in the water, which reduces the amount of nutrients available for algae to grow. You can purchase beneficial bacteria in liquid form and add it to your pond according to the instructions on the package. Be sure to use a product that is specifically designed for use in ponds to ensure the best results. Available at Pond Country retail stores.
3. Install a UV Clarifier to Kill Algae.

A UV clarifier is a device that uses ultraviolet light to kill algae and other harmful organisms in your pond. As water passes through the clarifier, the UV light disrupts the DNA of algae cells, preventing them from reproducing and causing them to die off. UV clarifiers are easy to install and can be used in conjunction with other methods, such as adding beneficial bacteria, to keep your pond clear and healthy. Be sure to choose a clarifier that is appropriately sized for your pond and follow the manufacturer’s instructions for installation and use. Available at Pond Country retail stores.
4. Use Barley Straw to Prevent Algae Growth.

Barley straw is a natural and effective way to prevent algae growth in your pond. As the straw decomposes, it releases compounds that inhibit the growth of algae. Instead of a bale of barley straw, simply add Barley Straw Extract in your pond and let it do its work. It may take a few weeks to see results, but over time, you should notice a reduction in algae growth. Available at Pond Country retail stores.
5. Add Aquatic Plants to Your Pond.

We conclude our list with the most important algae prevention of all – aquatic plants. Aquatic plants not only add beauty to your pond, but they can also help control algae growth. Plants like water lilies and lotus can provide shade, which helps to reduce the amount of sunlight that reaches the water and promotes algae growth. Additionally, plants absorb nutrients from the water, which can limit the amount of nutrients available for algae to grow. Be sure to choose plants that are appropriate for the size and depth of your pond. Pond Country has the Southeast region’s largest selection of aquatic plants such as water lilies, hyacinth (floaters), marginals, and lotus. In-stock and available now during April – November each year.
Honorable Mention: Algaecide

What is Pond Algaecide? It is a chemical product designed to control the growth of algae in ponds. It typically comes in liquid or granular form and is applied directly to the water. The active ingredients in pond algaecide work to kill or inhibit the growth of algae, which can help improve water clarity and reduce unpleasant odors super quickly. However, it’s important to note that pond algaecide can also have negative effects on other aquatic life and may not be a long-term solution to algae control.
While pond algaecide can be an effective solution for controlling algae growth, there are also some drawbacks to consider. One potential drawback is the risk of harming other aquatic life in your pond, such as fish or beneficial bacteria. Additionally, some types of pond algaecide may have negative environmental impacts if they are not used properly or if they leach into nearby water sources. Finally, pond algaecide may only provide a temporary solution to algae growth and should only be used in instances where algae removal needs to be done extremely quickly. Directions MUST be followed properly for size of the pond and dosage. NEVER overapply as this can harm the pond’s ecosystem and kill wildlife such as fish.
The Frog’s Advice: If you already have a lot of pond algae that you need to get rid of quickly, algaecide will work best for speed. It is not a long-term solution. The best method for removing algae is to prevent it altogether using a combination of the products listed in this blog. Also, it must be noted due to erroneous circulating internet myths — but never, NEVER, add bleach (Clorox) to your pond to kill algae. This wreaks havoc not only on your pond’s ecosystem, but will definitely kill all life including plants and fish.
Algaecide available at Pond Country retail stores.
Hey, what about that green, globby string algae?

The Frog’s Advice: Most of what we have discussed in this blog post is about green water algae, but what about string algae? The gloopy, glob of green goo that typically appears on the rocks around a pond’s margin or on a waterfall. That can be quickly removed with the usage of a product called Aquascape® EcoBlast Contact Granular Algaecide. It eliminates unsightly algae and debris from waterfalls, fountains, streams and rocks on contact. Simply sprinkle the treatment directly on the affected area and watch the algae disappear. It can be used any time of the year. It’s highly recommended for customers with pondless Infinity Waterfalls. Available at Pond Country retail stores.
