Millions of air bubbles are generated by the pump, making the water easier to clean and filter. Fine particles clump together and settle on the bottom of the pool, making them easier to remove. This process also oxidizes iron and manganese, which improves the clarity of the water. Aeration increases the number of negative ions, which helps neutralize free radicals and pollutants.
