How Do I Keep My Outdoor Fountain Water Clean Naturally?

The gentle murmur of a water fountain can create a tranquil ambiance in your outdoor space. However, as time goes on, the water can become stagnant, harboring algae and bacteria that can not only affect the aesthetics of your fountain but also pose potential health risks.

Maintaining clean fountain water is essential for the longevity and enjoyment of your outdoor feature. Here’s a comprehensive guide on how to keep your outdoor fountain water clean naturally, ensuring a sparkling and healthy environment for years to come.

1. Circulation and Aeration

The key to preventing stagnant water is to keep it moving. Ensure that your fountain is equipped with a pump that circulates the water continuously. This helps oxygenate the water and prevents algae growth. Consider installing a bubbler or fountainhead that creates surface agitation, further enhancing aeration.

2. Natural Water Clarifiers

• Barley Straw: Barley straw releases natural enzymes that inhibit the growth of algae and bacteria. Simply place a few bales of barley straw in a mesh bag and submerge it in the fountain water.

• Activated Carbon: This highly porous material acts as a filter, trapping impurities, chemicals, and odors from the water. Add activated carbon granules to the fountain basin or filtration system.

• Hydrogen Peroxide: In small doses (3% concentration), hydrogen peroxide acts as a disinfectant and oxidizer, killing algae and bacteria. Follow the instructions carefully and use it sparingly, as high concentrations can harm aquatic life.

3. UV Light Sanitization

Ultraviolet (UV) light can effectively kill microorganisms in water. Consider installing a UV light sterilizer in your fountain’s filtration system. It emits ultraviolet rays that damage the DNA of algae and bacteria, preventing their growth.

4. Beneficial Plants

Certain plants can help naturally clarify fountain water, absorbing nutrients that algae and bacteria thrive on. Plants like water hyacinths, water lilies, and hornworts can be placed in the fountain basin to aid in water filtration.

5. Regular Cleaning

Despite preventative measures, some maintenance is still required to keep your fountain water clean. Periodically drain the fountain, clean the basin and pump, and refill it with fresh water. Use a mild detergent and avoid harsh chemicals that can damage the fountain or aquatic life.

6. Winterization

If your fountain is exposed to freezing temperatures, it’s crucial to winterize it properly to prevent damage. Drain the water completely, disconnect the pump, and store it in a location where it won’t freeze. Cover the fountain to protect it from harsh weather conditions.

7. Chlorine or Bromine (As a Last Resort)

In cases of severe algae growth or contamination, you may consider using chlorine or bromine as a disinfectant. However, these chemicals should be used sparingly and carefully, as they can harm aquatic life and alter the water’s pH balance. Always follow the manufacturer’s instructions and test the water regularly.
