Which of the following is a common symptom of poor pool maintenance?

Algae growth is indeed a common symptom of poor pool maintenance. When a pool is not properly maintained, several factors can contribute to the proliferation of algae. This can include inadequate sanitation levels, which allow algae spores to thrive, poor circulation that prevents proper distribution of chemicals, and lack of regular cleaning that leads to the buildup of organic matter. Algae can not only make the water appear green and cloudy, but it also creates slippery surfaces, posing health risks to swimmers.

In contrast, clear water, consistent water temperature, and effective water circulation indicate good maintenance practices. Clear water suggests that the pool is well-filtered and properly treated with chemicals, while consistent water temperature often results from effective heating and circulation systems functioning correctly. Good water circulation helps to disperse chemicals evenly, reduce dead spots where algae might grow, and maintain water clarity, making it essential to a well-maintained pool environment.
