What mainly contributes to algae susceptibility in a pool?

The flow rate of water significantly impacts algae susceptibility in a pool because it affects the distribution of chemicals and sanitizers necessary for maintaining water clarity and safety. When water flow is insufficient, certain areas of the pool may experience inadequate circulation and uneven chemical distribution, leading to stagnant areas where algae can thrive. Algae need nutrients to grow, and stagnant conditions can allow organic materials to accumulate, creating an environment conducive to algae blooms. Maintaining a proper flow rate ensures effective filtration and circulation, which helps prevent algae growth by distributing chlorine and other sanitizers uniformly throughout the pool. This is crucial for keeping the entire pool sanitized and reducing the chances of algae proliferation.
