Water Quality and Water ChemistryMaintaining water quality and water chemistry in your spa is extremely important and should be a regular part ofyour 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 filtersystem helps maintain the water cleanliness and clarity by trapping most solid materials such as hair, and other debrisresulting from normal use. However, the most important part of maintaining water chemistry is keeping the proper levelof disinfectant in the water at all times. This is accomplished by adding chlorine or bromine to the water, which willcontrol particles too small to be trapped by the filter, such as bacteria and algae, and will oxidize any organic materials.Follow instructions provided here and with water quality products for the health and safety of spa users, as well as tomake your spa bathing as enjoyable as possible.MAINTENANCEFiltrationThe 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 capturedin the filters may bring about various undesirable waterquality conditions. These conditions can be correctedwith the use of spa treatment chemicals which areavailable from your Jacuzzi Whirlpool Bath dealer. Suchconditions include the following:Foaming: A defoamer is available to minimize foamingof the water. This condition is usually caused by theaddition of soaps or oils, or other fatty substances to thespa water. The interaction of these with hot water,especially at high pH (more alkaline), will cause thewater to foam. (Refer to Water Quality Definitions.)Oil Film or Cloudy Water: Add clarifier to congeal oilfilm on the water surface into globules sufficiently largeto be trapped by the system’s filter. Cloudiness iscaused by particles that are too small to be trapped in thefilter, and is also due to the presence of human body oils,lotions, and cosmetics. During normal use, these mate-rials can accumulate on the filter element and clog itspores. The addition of clarifier will make the waterclearer, but clogged filters must be cleaned as pre-scribed under the section entitled Filter Maintenance inthis manual.Hard Water: Add a demineralizer to break down ordeionize mineral particles present in the spa water.Follow the Filter Maintenance procedure describedin this manual to ensure optimum performance of yourspa’s filtration system.Water ChemistryYou can ensure better water chemistry by testingyour spa water every day and adjusting the chemicalbalance frequently. Obtain a water quality test kit,designed especially for spas, from your Jacuzzi Whirl-pool Bath dealer. The test kit must be of the type whichallows you to test for the disinfectant (chlorine) level, pH,and total alkalinity. Ensure that the chemicals used inyour spa are especially for spa use, and not for swim-ming pools, as water quality maintenance of spas and ofswimming pools is very different.Set up a daily program at first to check the disinfec-tant level, pH, and total alkalinity of the water. Familiar-ize yourself with the amount of chemicals to add and todetermine how often to make chemical adjustmentsduring normal use. Remember that the more heavily thespa is used, the more often you should check the waterchemistry.When adding any chemicals, always run the filtersystem to ensure complete dilution with the water.Do NOT add chemicals directly into the skimmer.9
