10MAINTENANCEWater Quality and Water ChemistryMaintaining water quality and the proper water chemistry in your spa is extremely important and should be a regular partof your spa maintenance program, as a neglected spa can be a breeding place for dangerous bacteria.The water quality of your spa is maintained by a combination of filtration and chemistry. The spa’s integral filter systemhelps maintain the water cleanliness and clarity by trapping most solid materials such as hair, and other debris resulting fromnormal use. The most important part of maintaining water chemistry, however, is keeping the proper level of disinfectantin the water at all times. This is accomplished by adding chlorine or bromine to the water, which will control particles too smallto be trapped by the filter, such as bacteria and algae, and will oxidize any organic materials. Follow instructions providedhere and with water quality products for the health and safety of spa users, and to make your spa bathing as enjoyable aspossible.FiltrationThe filtration system of your spa will keep your waterclear and clean if used properly. The filter cartridgeelements will trap most solid materials and debris in thewater. However, the presence of materials such as bodyoils or other particles which are too small to be captured inthe filters may cause various undesirable water qualityconditions. These conditions can be corrected with the useof spa treatment chemicals available from your JacuzziWhirlpool Bath dealer. Such conditions include the follow-ing:Foaming: A defoamer is available to minimize foaming ofthe water. This condition is usually caused by the additionof soaps or oils, or other fatty substances to the spa water.The interaction of these with hot water, especially at highpH (more alkaline), will cause the water to foam. (Refer toWater Quality Definitions on page 11.)Oil Film or Cloudy Water: Add clarifier to congeal oil filmon the water surface into globules sufficiently large to betrapped by the system’s filter. Cloudiness is caused byparticles that are too small to be trapped in the filter, and isalso due to the presence of human body oils, lotions, andcosmetics. During normal use, these materials can accu-mulate on the filter element and clog its pores. The additionof clarifier will make the water clearer, but clogged filtersmust be cleaned as prescribed under the section entitledFilter Maintenance in this manual (page 12).Hard Water: Add a demineralizer to break down ordeionize mineral particles present in the spa water.Follow the Filter Maintenance procedure described in thismanual (page 12) to ensure optimum performance of yourspa’s filtration system.Water ChemistryYou can ensure better water chemistry by testing yourspa water every day and adjusting the chemical balancefrequently. Obtain a water quality test kit, designed espe-cially for spas, from your Jacuzzi Whirlpool Bath dealer.The test kit must be of a type that allows you to test for thedisinfectant (chlorine) level, pH, and total alkalinity. Ensurethat the chemicals used in your spa are especially for spause, and not for swimming pools, as water quality mainte-nance of spas and of swimming pools is very different.Set up a daily program at first to check the disinfectantlevel, pH, and total alkalinity of the water. Familiarizeyourself with the amount of chemicals to add and determinehow often to make chemical adjustments during normaluse. Remember that the more heavily the spa is used, themore often you should check the water chemistry.When adding chemicals, always run the filter system toensure complete dilution with the water. Do not addchemicals directly into the skimmer.
