“Why has my pool turned green?”
“Why has my pool turned green?” A crystal clear swimming pool on a hot summer’s day is an inviting sight. However, the invitation becomes less appealing when the pool turns green. It’s a nightmare for every pool owner to see their blue pool turn green. But, there’s no need to panic as it is a fairly simple problem to fix and you don’t have to fill it with cement just yet.
Your swimming pool could turn green due to the growth of algae. If you notice that the pool water has turned slightly green, it means that the algae growth has just started. However, if the water is dark green with patches of green growth on the surfaces of the pool, such as the steps, it indicates that the situation is worse and the pool is closer to becoming a fish pond. But, there is no need to panic as algae are just aquatic organisms that grow through photosynthesis. They enter our swimming pools through various means such as the wind or rain, and can multiply quickly if the conditions are favorable. If your pool water is imbalanced, lacks sanitizer or has poor circulation and filtration, algae will easily get a grip and thrive.
“I am wondering how to restore the blue color of my pool. Can you help me with that?”
To get rid of algae in your pool, you need to start by scrubbing it with a stiff-bristled or metal brush. Your pool skimmer net will also come in handy for removing any floating algae and other organic matter. After that, test your pool water to check its pH, total alkalinity, and chlorine levels. Your swimming pool’s pH should be between 7.2 and 7.6, the total alkalinity between 80 to 150 parts per million, and the free chlorine between 1 and 3 parts per million.
To bring your pool back to normal, you need to shock it with a pool shock high in chlorine. If your pool closely resembles a swamp, you may need to shock it three or even four times. Run your pump through a course, and clean your filter regularly to remove any collected algae. Once you’re done, retest your pool water and make sure that it is balanced.
To avoid going through this again, maintain your sanitizer levels regularly and top them up whenever necessary. In just a matter of days, blue waters will be returning to your pool if you follow these steps.
“What should I do if the water in my swimming pool appears green, but it’s not due to algae?”
Dealing with a green pool can be a bit tricky. Sometimes, the issue is not just algae thriving in the water. If your pool is greenish but still clear, it may be due to the presence of dissolved metals. To get rid of this, add a metal remover to your pool and adjust the pH and total alkalinity. But if your pool is glowing green, it could be over-stabilized, with high chlorine and stabilizer levels. In this case, you need to reduce the level of stabilizer by draining some of the pool water if the level is over 100 parts per million. Make sure to keep the stabilizer level between 40 and 80 parts per million and retest the pH. If needed, shock your pool to restore the balance.
