What is a common misconception about pool cleaning?

Once a pool has been cleaned, the common misconception is that no further maintenance is required. This is incorrect because regular maintenance is essential to keep the pool in a healthy and usable condition. Even after a thorough cleaning, factors such as debris accumulation, water balance, and hygiene still require ongoing attention.

For instance, debris can settle back into the pool, necessitating regular skimming and vacuuming. Additionally, water chemistry can fluctuate due to factors like bather load, weather changes, and the introduction of organic materials, all of which require continual chemical testing and adjustments. Therefore, consistent maintenance is crucial, ensuring water quality and preventing the growth of algae or bacteria.

The other choices touch on valid aspects of pool cleaning but do not align with the misconception in question. Cleaning indeed involves physical and chemical methods, and while debris removal is critical, regular maintenance remains crucial even after a thorough cleaning. Lastly, relying solely on chemicals without physical cleaning will not effectively maintain pool hygiene or clarity.
