Remove and prevent algae forming in a fountain with this guide. Over time, if you’re not careful, your once-lovely water fountain can turn into a green, slimy, smelly mess. The culprit is algae, which grows rapidly in water with low oxygen levels, especially in a sunny location. You don’t have to use harsh chemicals or clean your fountain daily to remove and prevent algae, though. A little vinegar, some elbow grease and preventative treatments will keep your fountain sparkling and clear.
Consult your fountain's instruction manual, if provided, to check for any special tips or cautions regarding cleaning the fountain. Some fountain materials require special care.
Use white vinegar and an old soft-bristled toothbrush to clean tough algae growth. White vinegar is mild enough to be used on nearly any fountain surface, and will remove most stains and discolored spots.
Place the fountain in a spot where it doesn't receive direct sunlight, if possible. This will cut down on the incidence of algae blooms.
