    DECATUR, Ga., April 23 /PRNewswire Interactive News Release/ --
 BioGuard(R), one of the world's leading manufacturers of pool and spa products
 is leading swimming pool retailers and swimming pool owners to a greater
 understanding of the industry and industry jargon.  Swimming pool retailers
 and consumers alike share the responsibility of knowing how to maintain clean,
 sparkling water.  But for consumers, it's all Greek when they walk into a
 store and realize that they haven't had chemistry in years.  Here are some of
 the most commonly used terms every swimming pool owner should know:
 
     Algicide              Products that prevent or control algae growth. The
                           term algicide is used for both algistats and true
                           algicides interchangeably.
 
     Bromine               A halogen element; brominated compounds provide an
                           alternative primary sanitizer for pools; widely used
                           in spas and indoor pools (Ideal levels are 1.0 - 3.0
                           ppm for residential pools; 3.0 to 5.0 ppm for
                           commercial pools).
 
     Chlorine Demand       The amount of free available chlorine residual
                           needed to destroy organic contaminants and establish
                           a stable residual for effective sanitation. If a
                           pool is unable to maintain or measure a free
                           available chlorine residual it is likely that the
                           pool has a chlorine demand.  This chlorine demand
                           must be satisfied before you can maintain a stable
                           chlorine residual and effectively sanitize your
                           pool.  Chlorine demand is measured in the amount of
                           free available chlorine residual needed to destroy
                           the organic contaminants causing your chlorine
                           demand.
 
     Chlorine              A halogen element, chlorine compounds are widely
                           used to sanitize pool water.
 
     Combined Chlorine     Substance formed when free available chlorine
     (Chloramines)         combines with urine, sweat or other contaminants.
                           Causes chlorine odor as well as irritation of the
                           skin and eyes.  The difference in your Total
                           Chlorine reading and your Free (Available) Chlorine
                           reading is combined chlorine.
 
     Free (Available)
      Chlorine             A form of chlorine compound capable of destroying
                           bacteria and algae.  Preferred range: 1.0 to 3.0
                           PPM.
 
     Halogen               A family of elements containing chlorine, bromine,
                           fluorine, iodine and astatine.  Halogens are
                           commonly used in a variety of sanitizing situations.
 
     Lint Pump/Pump Pot    A bowl-like container located in the plumbing of the
                           pool directly in front of the pump.  This container
                           has a basket insert to catch leaves and other debris
                           to prevent these from entering the pump.
 
     Oxidizer              A chemical that breaks up contaminants such as
                           suntan oils, cosmetics, perspiration and windblown
                           dirt found in pool water.  Oxidizers are used to
                           break down chloramines.  Also known as "Shock".
 
     pH                    A way of measuring the acidity or alkalinity of
                           water.  This is the most important part of chemical
                           balance.  Proper pH makes swimmers more comfortable,
                           keeps water clear, protects pool surface and
                           equipment and allows sanitizers to work more
                           efficiently.  pH is measured on a scale from 0-14.
                           Preferred range: is 7.4 - 7.6.
 
     PPM                   Parts Per Million is a unit of measurement for
                           chemical concentration.
 
     Sanitizers            Products that are added to pool water in order to
                           control bacteria growth.
 
     Saturation Index      A value based on water temperature, total
                           alkalinity, calcium hardness and pH.  This value
                           predicts the tendency of the pool water to be
                           corrosive, neutral or scale forming.
 
     Shock                 An oxidizer used in the maintenance of pool water.
                           Eliminates contaminants such as suntan oils,
                           cosmetics, perspiration and windblown dirt found in
                           pool water.
 
     Skimmer               A device in a pool wall that continuously removes
                           the surface water and floating debris to be taken
                           away by the filter.
 
     Skimmer Weir          A flap-like piece located within the skimmer at the
                           entrance point for water from the pool into the
                           skimmer.  The weir provides a dropping surface for
                           water exiting the pool into the skimmer when the
                           water level of the pool is properly adjusted.  This
                           dropping surface creates the maximum skimming
                           action, providing for removal of floating debris
                           from the pool surface.
 
     Superchlorination     The process involving the adding of chlorinating
                           compound (3 to 5 times the usual dosage) to destroy
                           chlorine demand compounds and combined chlorine.
 
     Total Alkalinity (TA) Total Alkalinity is a measure of pool water's
                           ability to resist pH change. Total Alkalinity is
                           also measured as part of every BioGuard(R) Insignia
                           and Authorized Dealer's free water analysis.  Ideal
                           range is 125 - 150 ppm.
 
     Total Chlorine        The sum of free available chlorine (active
                           sanitizing form of chlorine) and combined chlorine
                           (odorous, non-active form of chlorine) present in
                           water.
 
     Water Balance         The proper ratio of mineral content and pH that
                           prevents pool water from being corrosive or scale
                           forming.  The chlorine and bromine residuals work
                           best in water that is properly balanced.  Balanced
                           water is also more comfortable for swimmers and
                           better for equipment.  Water Balance is determined
                           by making sure that swimming pool water has the
                           appropriate levels of pH (7.4 - 7.6), Total
                           Alkalinity (125 - 150 ppm), and Calcium Hardness
                           (200 to 275 ppm for Plaster & SoftSwim(R) Pools;
                           175 - 225 ppm for all other types).
