What is a common cause of pool algae growth?

Insufficient sanitizer levels and poor water circulation create an environment conducive to algae growth in pools. Sanitizers, such as chlorine, play a crucial role in controlling and preventing the growth of algae by killing the microorganisms and bacteria present in the water. When these levels are inadequate, it allows algae spores, which are often present even in the cleanest water, to flourish unchecked.

Additionally, poor water circulation means that water is not being adequately filtered, leading to stagnant areas that can become breeding grounds for algae. Effective circulation helps distribute the sanitizer throughout the pool, ensuring that all areas are treated and that algae do not have the opportunity to establish themselves.

Given these aspects, it’s clear that maintaining the right balance of sanitizer and ensuring proper water circulation are both critical components in preventing algae growth in swimming pools.
