On a scale of 0 to 14, 7.6 is the ideal point of balance. A measurement below 7.2indicates that your water is more acidic. This water condition results in corrosion of the equipment’s metalcomponents. A measurement above 7.8 indicates that your water is more alkaline. This water condition causescalcium deposits and scaling in the equipment and hot tub. Both conditions are detrimental and cause damage.NOTE: Calcium deposits can also cause a restriction of air and water through your jets. Using astain & scale remover regularly, will greatly reduce the chance of this occurring.CHLORINEGranulated chlorine must be used to remove bacteria and other organic matter from the water. Little or no chlorinecauses water to turn green and unhealthy. Too much chlorine causes water to smell pungent, irritates the eyes andskin, and can cause damage to the heater tube on the power pack.NOTE: Improper pH will destroy the pump seals and heater elements. Damage to componentscaused by improper pH balance or other improper chemistry will not be covered under warranty.Fantasy Spas strongly discourages the use of chemicals that contain Hydrogen Peroxide.
