Section 4. Pool Water Preparation
4.1 Determining Pool Size (Gallons of Water in Your Pool)
• Rectangular Pools
Averagelength(feet)xaveragewidth(feet)xaveragedepth(feet)x7.5=galloncapacity.
• Circular Pools
Diameter(feet)xdiameter(feet)xaveragedepth(feet)x5.9=galloncapacity.
• Oval Pools
Longdiameter(feet)xshortdiameter(feet)xaveragedepth(feet)x5.9=galloncapacity.
• Sloping Sides
Multiplytotalgallonsby0.85=galloncapacity.
4.2 Determining Pool Size (Litres of Water in Your Pool)
• Rectangular Pools
Averagelength(metres)xaveragewidth(metres)xaveragedepth(metres)x1000=litrescapacity.
• Circular Pools
Diameter(metres)xdiameter(metres)xaveragedepth(metres)x790=litrescapacity.
• Oval Pools
Longdiameter(metres)xshortdiameter(metres)xaveragedepth(metres)x790=litrescapacity.
• Sloping Sides
Multiplytotallitresby0.85=litrescapacity.
4.3 Selecting Model Size

(SeeGeneralRuleofSizingnotesbelow)
General Rule of Sizing: Inareaswithyear-rounduseandhighwatertemperatures,suchasFlorida,Texas,Arizona,
LasVegasandSouthernCalifornia,thefollowingmustbeconsidered:
Year Round Use:Up-sizingtheJandy®AquaPure®Eichlorinegeneratingdeviceoraddingmorethanoneunit
mayberecommendedforpoolsthatareclosetothemaximumsizeandusedyearround.Pleaseconsultyourpool
professional.
High Water Temperatures: Because chlorine demand increases with the rise of water temperature, adjustments
must be made in order to keep up with chlorine demand. In hot summer months, where the water temperature
rises above 85ºF, you must increase the pump run time and increase the percentage (%).
4.4 Chemistry You Need to Know
• Chlorine Stabilizer(cyanuricacid)isneededtomaintainproperlevelsofchlorine.Mostnon-stabilizedchlorine
isdestroyedbytheUVradiationfromthesunwithintwo(2)hours.Chlorinestabilizershouldbemaintained
between30-50ppm.Forindoorpools,itisnotnecessarytoaddchlorinestabilizertotheswimmingpoolwater.
• Nitratescancauseextremelyhighchlorinedemandsandwilldepletechlorinefromyourswimmingpool.In
somecasesnitratesmayevenloweryourchlorinelevelstozero.Yourlocalpoolprofessionalcantestfornitrates.
Make sure nitrates are not present in your pool.
