Gather the necessary materials

Gotta grab some gloves, a scrub brush, and a bucket of warm water to get started on cleaning that algae from your concrete fountain.

First, you need to choose the appropriate cleaning techniques to remove the algae effectively. Algae can be slippery and difficult to remove, so you need to be careful not to damage the surface of the fountain.

There are several algae removal products available on the market that you can consider using. Some of these products are specifically designed to clean concrete surfaces, while others are safe for use on various types of materials.

You can also make your own algae removal solution using household items such as vinegar or baking soda. However, before using any product, make sure to read the instructions carefully and test it on a small, inconspicuous area of the fountain first.

Drain and prepare the fountain

First, it’s important to empty the water and remove any debris from the bottom of the basin. This will make it easier to clean the algae and prevent any clogs in the drainage system. Use a bucket or a sump pump to remove the water, and once the fountain is empty, you can start preparing it for cleaning.

Before you start cleaning, you should cover the fountain to protect it from any cleaning products that may harm the concrete or the surrounding area. You can use plastic sheeting or a tarp to cover the fountain, and secure it with tape or bungee cords. Then, you can start choosing the cleaning products that you will use to clean the algae from the fountain. Make sure to choose a product that is safe for concrete surfaces and won’t harm any plants or animals nearby.

Apply the cleaning solution

Now that you’ve drained and prepared your fountain, it’s time to apply the cleaning solution. Make sure to carefully follow the instructions on the product label to ensure safety and efficiency.

Using a soft-bristle brush, gently scrub the surface of the fountain to remove any remaining algae or grime. Once you’ve scrubbed the entire fountain, be sure to rinse thoroughly with clean water to remove any leftover cleaning solution.

Follow instructions on the product

To effectively clean the algae from your concrete fountain, you’ll want to follow the instructions on the cleaning product. Before using any cleaning product, it’s important to take safety precautions. Wear gloves and eye protection to prevent any possible irritation or injury.

If the cleaning solution is harmful to plants or animals, make sure to cover them or remove them from the area. When using the cleaning product, carefully read and follow the instructions on the label. Different products may have different application methods and dilution ratios, so it’s important to use the correct amount for your fountain.

Some products may require you to pre-wet the area, while others may need to be applied directly to the algae. Following the instructions on the product will ensure that you effectively clean the algae from your concrete fountain without causing any damage. If you’re unsure about which product to use, consult with a professional or do some research on product alternatives.

Use a soft-bristle brush to scrub

Using a soft-bristled brush gently scrubs the surface, ensuring that the cleaning product penetrates all the nooks and crannies of the fountain. It’s important to choose the right brush for the job, as using a hard-bristled brush can scratch the surface of the concrete.

A soft-bristled brush is gentle enough to avoid damaging the fountain, but still effective enough to remove algae buildup. In addition to regular cleaning, algae prevention techniques can also be implemented.

These include adding an algaecide to the water, reducing the amount of sunlight the fountain receives, and regularly cleaning the fountain to prevent algae from taking hold. By taking preventative measures and using the right brush for cleaning, your concrete fountain can remain algae-free and beautiful for years to come.

Rinse thoroughly

After gently scrubbing the surface with a soft-bristled brush, make sure to thoroughly rinse off all the cleaning product and any remaining dirt or debris. This is an important step in the cleaning process because it ensures that all the algae has been removed and the fountain is left looking clean and fresh.

To make sure you rinse the fountain properly, here are some best practices to follow:

  • Use a hose or a bucket of clean water to rinse the fountain.
  • Make sure that all areas of the fountain are rinsed, including hard-to-reach areas.
  • Pay special attention to areas that are prone to algae growth, such as corners and crevices.
  • Keep rinsing until the water runs clear and there’s no sign of cleaning product or debris.

Maintenance tips are also important in keeping your concrete fountain clean and free from algae growth. Regular cleaning and maintenance will prevent algae from forming and will also help prolong the life of your fountain.

By following these best practices and maintenance tips, you can enjoy a beautiful and clean fountain for years to come.

Preventing future algae growth

Keep your concrete fountain algae-free by regularly scrubbing the surface and changing the water every few weeks. However, if you want to prevent future algae growth, consider using algae-resistant materials when building or repairing your fountain. These materials can include copper or brass fixtures, which have been shown to inhibit algae growth.

You can also incorporate natural algae prevention methods, such as adding plants or fish to your fountain. Another way to prevent algae growth is to keep the water moving. This can be done through the use of a fountain pump or a small waterfall feature. The movement of the water prevents stagnant areas, which are ideal environments for algae to thrive.

Additionally, make sure to keep your fountain in a location that receives some sunlight, as this can help to naturally inhibit algae growth. By taking these preventative measures, you can keep your concrete fountain looking beautiful and algae-free for years to come.

Final touches

Don’t forget to add some decorative accents to your newly cleaned concrete fountain. A few well-placed rocks or plants can give your fountain a personal touch and make it a focal point in your outdoor space.

Consider adding some water plants like lilies or lotuses to help keep the water clean and clear. These plants not only provide a natural filter, but they also add a beautiful touch to your fountain.

In addition to adding decorative elements, it’s important to continue with regular water feature maintenance to prevent future algae growth. This includes regularly cleaning the fountain and changing the water every couple of weeks.

You can also use algae prevention products or natural remedies like vinegar or baking soda to keep the water clear.

With proper maintenance and a few decorative accents, your concrete fountain can be a beautiful addition to your outdoor space for years to come.


Congratulations! You’ve successfully cleaned the algae from your concrete fountain and it looks brand new again. Remember, regular maintenance is key to preventing future growth.

Here are a few tips to keep in mind:

  • Firstly, keep the water level in your fountain consistent. Algae growth thrives in stagnant water, so make sure to keep the water moving by adding a fountain pump or water feature.

  • Secondly, consider adding an algaecide to your fountain. This will help to prevent future growth and keep your fountain looking pristine.

By following these simple steps, you can enjoy a clean and beautiful concrete fountain for years to come. Don’t forget to show off your hard work to your friends and family and maybe even treat yourself to a relaxing afternoon by your newly cleaned fountain. Happy cleaning!
