Impurities in the water can also cause the formation of algae in a fountain. To prevent this, avoid using contaminated water, such as unfiltered water from a pond or stream. Instead, use treated tap water or distilled water that has been purified and had all impurities removed. This is particularly important for indoor water features where you don’t have to worry about rainwater or outdoor pollutants entering the water.
Utilize Commercial or Homemade Algaecide
To minimize algae growth in your fountain, you can also add certain substances to the water. Garden centers offer a variety of products known as algaecides, which are designed to prevent algae from growing in pools, ponds, and fountains. These products can either kill existing algae or prevent new algae from forming in clean water. When selecting an algaecide for fountains, it is best to choose a natural option to ensure the safety of wildlife and humans. Application instructions may vary depending on the product and the size of the fountain. Generally, algaecide is diluted with water before being poured into the fountain near its pump. As the algaecide starts working against the algae, the water may become foamy, but it will eventually become clear again.
If there are no plants or other aquatic life living in the fountain, a mixture of household bleach and fountain water can be an effective homemade algaecide. However, it is generally not recommended because it can damage the fountain’s material and pose a potential danger to animals and children who may come into contact with the water. Alternatively, you can use oxygen bleach as a DIY algaecide. Unlike chlorine bleach, oxygen bleach does not contain toxic ingredients. If using powdered oxygen bleach, make sure to dissolve it completely in water before adding it to the fountain.
Regular cleaning of the fountain should help keep algae growth to a minimum. If you notice excessive algae growth, a simple commercial or homemade algaecide can help stop or slow down the growth, allowing you to enjoy clear water in your fountain.
