Green pool

As the recent Hurricane Beryl swept through Houston, many homeowners found themselves facing the aftermath of power outages. One common issue for pool owners during such times is the unsettling sight of a green pool. At 3D Pools and Landscape, we understand the frustration of seeing your pristine pool turn into a murky mess. Here’s why it happens and how you can restore your pool to its sparkling glory.

Why Does Your Pool Turn Green After a Power Outage?

  1. Lack of Filtration: During a power outage, your pool’s filtration system stops working. This allows debris, dirt, and organic matter to accumulate, which creates a breeding ground for algae.
  2. Chemical Imbalance: The loss of power disrupts the circulation of water and chemicals, leading to an imbalance. Without proper circulation, chlorine and other sanitizers become ineffective, allowing algae to flourish.
  3. Warm, Stagnant Water: Houston’s warm climate, especially after a hurricane, creates ideal conditions for algae growth. Without the pool pump running, the water becomes stagnant, exacerbating the problem.

Essential Pool Maintenance Tips After a Power Outage

To prevent and combat a green pool, follow these expert tips from 3D Pools and Landscape:

  1. Remove Debris Immediately: As soon as it’s safe, remove leaves, branches, and other debris from your pool. This prevents organic matter from decaying and feeding algae growth.
  2. Check and Balance Water Chemistry: Test your pool water for pH, chlorine, and alkalinity levels. Adjust these levels to restore balance. Aim for a pH of 7.2-7.6 and free chlorine levels of 1-3 ppm.
  3. Shock Your Pool: Once the power is restored, shock your pool with a high dose of chlorine. This helps to kill off algae and bacteria that may have started to grow during the outage.
  4. Run Your Pool Pump Continuously: Keep your pool pump running continuously for at least 24-48 hours after power is restored. This helps circulate the water and chemicals, preventing further algae growth. 
  5. Brush and Vacuum: Brush the pool walls and floor to loosen algae and debris. Vacuum the pool thoroughly to remove any settled particles.
  6. Use Algaecide: Consider using an algaecide as an added measure to prevent algae growth. Follow the manufacturer’s instructions for proper application.
  7. Clean Your Filters: Clean or backwash your pool filters to ensure they are free of debris and can function efficiently. 
  8. Maintain Regular Pool Care: Once your pool is clear, maintain regular pool care routines. Keep an eye on water chemistry, run the pump daily, and clean the pool regularly.
