Why Do Pools Turn Green? Exploring The Science Behind Algae Infestations

Is it safe to swim in a pool that appears green? If your pool water has turned green due to the presence of algae, it’s essential to exercise caution before taking a dip. Green algae can create an environment conducive to the proliferation of harmful bacteria, such as E. Coli. Opting to swim in a pool with algae increases the likelihood of experiencing skin irritation, infections, or even falling ill as a result of exposure to these pathogens. Ensuring your pool water is properly maintained and free from excessive algae growth is crucial for a safe and enjoyable swimming experience. (Published on August 9, 2022)

Maintaining proper circulation is crucial in preventing your pool from turning green. When water becomes stagnant, it provides an ideal environment for algae, bacteria, and various contaminants to flourish, leading to the dreaded green hue. To ensure effective circulation, it’s imperative to keep your pool pump clean, well-maintained, and running consistently. This consistent flow of water helps thwart the growth of unwanted microorganisms. This advice was last updated on November 15, 2022.

The green coloration in swimming pool water is primarily attributed to the presence of algae. Algae blooms occur when the pool’s Free Chlorine levels are low. Factors such as prolonged exposure to high temperatures, heavy rainfall, or inadequate water circulation can further exacerbate the risk of algae development. It’s crucial to use a preventative algaecide to mitigate these conditions. This treatment helps maintain proper chlorine levels and prevents the growth of algae, ensuring your pool remains clean and clear.
