POOL FILTERS The filters in this system are high-rate sand filters. Sand filters consist of a large tank, made of fiberglass, concrete or metal, containing a thick bed of special-grade sand, which has a squarish shape. During filtering operation, dirty water from the pool comes in through the filter’s inlet pipe, which leads to the water distribution […]
POOL PUMP SYSTEMS To most of us, a pool is, more or less, a big hole in the ground. We don’t see most of the expensive machinery in a pool system, because it’s usually tucked away in nearby pump room. But this is the stuff that really makes the pool work. The heart of the

Chlorine gained its name from the Greek word “Khloros”, which means “green”. Chlorine today is one of the most widely produced chemicals in

POOL PH LEVELS The water’s pH is a measure of its total acid-alkalinity balance — the relative proportion of acids and alkalisin the water. Simply put, water that is either too acidic or too alkaline will cause undesirable chemical reactions. If the water is too acidic, it will corrode metal equipment, cause etching on the surface materials and cause skin irritation.
POOL CHEMICALS A pool’s filter system does the heavy lifting in keeping the water clean, but it takes chemistry to do the fine-tuning. It’s important to carefully manipulate the chemical balance in pools for several reasons: Dangerous pathogens, such as bacteria, thrive in water. A pool filled with untreated water would be a perfect place for
