What causes swimming pool water to turn green?

Green pool water is mainly caused by growing algae. When the disinfection of pool water is not enough, algae will grow. High levels of nutrients such as nitrogen and phosphorus in poll water will promote the growth of algae. In addition, water temperature is also an important factor affecting algae growth. During hot seasons, algae will reproduce faster, causing the pool water to turn green in a few days or even less.

Most algae are tiny plants that grow and reproduce in water, while blue algae are actually bacteria and pink algae are fungi. Under certain conditions, algae bloom and cause water to appear green. Algae would affect water quality and provide places for bacteria to grow, so they pose potential threats to human health.
