How Algae Affects Your Water Fountains
Algae in a water fountain can be caused by many things, such as fish waste, organic materials from plants and leaves, or previous blooms combined with excessive sunlight.
Two main types of algae can be found in outdoor water features such as ponds and fountains: planktonic algae, a floating microscopic algae, and filamentous algae, also known as string algae. Filamentous algae is a single-cell plant that forms long and visible threads, chains, or filaments in ponds and fountains.
- Planktonic Algae – Planktonic Algae is a floating microscopic alga, the source of the blooms resembling pea soup, and can color ponds and water fountains green, blue, or brown. If controlled, this type of algae may not look good, but it can benefit your fountain as it is the start of a food chain for fish, and it shades the bottom of your fountain or pond to prevent other nuisances, plants, and algae from growing.
- Filamentous Algae – Also known as string Algae, this type of algae is a single-cell plant that forms long and visible threads, chains, or filaments in your ponds and fountains. They grow at the bottom of a pond or fountain in more shallow water and on rocks and other water plants. They will intertwine and form mats that resemble wool/ These algae may rise to the surface of the water and may resemble scum, they also make an excellent breeding ground for bugs and worms that are unwanted, and they can be quite unsightly.
