Which cleaning method is effective for destroying algae?

Brushing both walls and floors thoroughly is an effective cleaning method for destroying algae because it dislodges algae and other debris from surfaces, making them susceptible to sanitizers and other treatments. Algae can attach firmly to walls, floors, and other surfaces, and simply skimming the surface or vacuuming may not remove the algae embedded in these areas. When you brush, you are not only removing the visible presence of algae but also allowing the chemical treatments, such as chlorine or algaecides, to reach and kill the algae more effectively.

This thorough brushing action helps in breaking apart any clumps of algae and making them easier to capture and remove. Additionally, it disrupts the growth cycle of algae by removing the spore sites, preventing them from regrowing quickly.

Other methods mentioned, such as skimming or using flocculants, might aid with general cleaning or clarity but do not address the root presence of algae. Vacuuming might remove some algae but can miss areas where algae have adhered to surfaces, particularly if not combined with brushing. Therefore, brushing combined with chemical treatment is a proven method to effectively eradicate algae in pool cleaning.
