What is the main consequence of algae growth in pools?

Algae growth in pools is problematic primarily because it can significantly compromise both the safety and aesthetic appeal of the water. When algae proliferate, they often result in murky or discolored water, making it uninviting for swimmers. More critically, certain types of algae can produce toxins that are harmful to humans, leading to health risks such as skin irritations, respiratory concerns, and gastrointestinal issues if ingested.

Moreover, the presence of algae can create slippery surfaces around the pool, increasing the risk of accidents like slips and falls. The aesthetic issues and potential health hazards are compelling reasons for pool operators to maintain proper water chemistry and sanitation practices to prevent algae growth.

In contrast, options that suggest benefits such as adding nutrients or improving water filtration and chemical stability do not accurately reflect the consequences of algae presence in a pool. While it’s true that nutrients are involved in the growth process of algae, this does not translate to a positive outcome for the swimming environment. Additionally, algae do not assist in water filtration and can disrupt the overall chemical balance, rather than stabilize it. This reinforces the idea that controlling algae growth is essential for maintaining a safe and pleasant swimming experience.
