This article will look deeper into the mechanisms of testing water quality parameters and help to anticipate and remove interferences and errors when conducting water tests. The water parameters under review will include pH, total alkalinity, calcium hardness, cyanuric acid, and free and total chlorine.
Preventive maintenance refers to routine upkeep to ensure pool equipment continues to operate efficiently, whereby preventing any unanticipated downtime and the associated costs from equipment failure.
Water balance in pools and hot tubs is a relatively simple concept. Take the readings from the most commonly tested parameters (pH, total alkalinity [TA], calcium hardness [CH], water temperature, and total dissolved solids [TDS]) and then use these values in a mathematical formula that produces a number.
Dealing with pool and hot tub water chemistry issues is sometimes confusing and occasionally frustrating because of the many critical components involved. A basic understanding of this topic is often not enough. Sometimes it requires gaining a better understanding of what it takes to maintain healthy, balanced water.
Despite some long-held beliefs, a hot tub is not simply a small pool. There are major differences between the chemistry of these aquatic environments that are unique enough to warrant a separate discussion. For service technicians, understanding these differences and knowing how to alter a testing and treatment regimen geared for pools to one suited for hot tubs is critical for maintaining healthy water for their customers.
Hach/ETS, the manufacturer of AquaChek® pool and spa test strips in Elkhart, Ind., recently received International Organization for Standardization (ISO) 9001:2008 certification for all water testing products it manufactures.
