As spring approaches, so do warmer days, more rain, and increased pool activity. But with the rain comes a hidden challenge: black algae. Proximity to water and vegetation means your pool may be at risk of developing this stubborn algae if precautions aren’t taken.
Rainwater often washes black algae spores from screens, plants, trees, and decks into your pool. In normal conditions, the chlorine levels in your pool should be enough to prevent the algae from taking root. However, heavy rains can disrupt your pool’s chemistry, allowing black algae to flourish. Once it’s established, black algae is tough to remove, often requiring multiple treatments. That’s why prevention is key.
Prevent Black Algae Before It Starts
To keep your pool in great shape this rainy season, focus on stopping black algae before it has a chance to enter your pool. Our experience points to these common culprits and preventive measures:
- Clean Decks, Furniture, and Screen Enclosures (if applicable): Regularly clean or pressure wash patio furniture and decks to remove algae spores. Add bleach and water. (Important: when mixing water and chemicals – always add chemicals to water, never water to chemicals.)
- Maintain Screens and Rails: Schedule periodic pressure washing for your screen and rail systems.
- Ensure Proper Drainage: Loosen bottom screen rails at low spots to prevent water pooling on the deck.
- Gutter Cleaning: Aim your downspout away from your pool and remove debris from gutters after the winter season to avoid runoff into your pool.
- Trim Overhanging Plants: Cut back trees and shrubs that extend over the pool to reduce the transfer of spores.
- Pressure Wash Rocks and Features: Thoroughly clean rocks and water features around your pool to eliminate potential algae sources.
While these steps can significantly reduce the risk of black algae, it’s important to note that spores can also be carried by wind, making total prevention challenging.
