What is the best way to prevent algae growth on stone outdoor tables near fountains?

Algae growth on stone outdoor tables near fountains can be a persistent issue, especially in humid or shaded areas. To prevent algae buildup, regular cleaning is essential. Start by scrubbing the table surface with a mixture of water and mild detergent or a specialized stone cleaner. Avoid harsh chemicals that could damage the stone. For tougher algae, use a solution of water and white vinegar or a diluted bleach solution, but rinse thoroughly afterward.

Another effective method is to ensure proper drainage around the fountain area to reduce moisture accumulation. Trim nearby plants or trees to allow more sunlight, as algae thrive in damp, shaded environments. Applying a stone sealer can also create a protective barrier, making it harder for algae to adhere to the surface.

Lastly, consider using natural algae inhibitors like copper strips or zinc-based products near the fountain. These materials release ions that deter algae growth without harming the stone. By combining these strategies, you can keep your stone outdoor tables clean and algae-free, enhancing their longevity and appearance.
