The water in a swimming pool can easily get polluted in a short time if you ignore your maintenance responsibilities. Not only does human perspiration become part of the water, so does residue from cosmetics and personal care products. The combination of these chemicals with moisture and heat creates conditions for the manifestation of fungi such as algae. Failing to clean the water routinely can spread bacteria and illness.
Proper pool maintenance starts with learning your pool components, which can be divided into suction, filtration, and pressure parts.
Suction equipment includes the skimmer, main drain, and suction lines
The filtration system consists of a pump and filter
The pressure system sends water through return lines back into the pool.
Water passes through a pump, shifting the force from pulling to pushing action. As return jets push water through the pool, the skimmer basket collects debris floating on the water's surface. The water is cleaned by a combination of filtering and application of chlorine, which kills viruses and bacteria. A pool heater is an option for comfort but not a requirement for good maintenance since it doesn't affect circulation or filtration.
