Circulation is a key factor that will make the difference between a fun, healthy pool environment and an unsafe, problematic one. All pool pumps should run for 24 hours. Without proper circulation, your filtration system will not work effectively nor will your chemicals be evenly distributed, therefore compromising the equipment's longevity as well as the overall water quality. When there is no circulation in the pool, we can not filter out debris or bather waste.
Lack of circulation will also allow bacteria and other microorganisms to adhere to the pool surface and start to reproduce. Some bacteria can double in population within 20 minutes.
