POOL WATER CARE FOR VINYL LINER POOLS
With proper pool water care, your vinyl liner pool is designed to hold the same water for many years. You filter it, and you treat it over and over again, as part of your pool water care. Over time the water can drift out of balance and cause corrosion, scaling, or staining. Prevent these problems by keeping the water balanced. Use a good quality test kit to measure PH, Alkalinity, Calcium hardness, and chlorine residual.
Also tests might be needed for copper, iron, and chlorine stabilizer, to spot trends that could also cause problems.
PH is a numbered scale from 0 to 14, that measures the acidity(that’s below 7), or alkalinity (that’s above 70, of the water in a vinyl liner pool. Proper PH is 7.2-7.8. Low PH causes corrosion and wrinkles in vinyl liners. High PH causes cloudiness, scale and ineffective chlorine.
Total Alkalinity measure the level of a chemical that stabilizes or anchors the PH. The proper range for TA is 80-120 for vinyl liner pools. Keepin within this range will prevent PH drift and the problems mentioned above. High levels of TA can easily be lowered by adding PH Decreaser or Muriatic Acid.
Calcium measures calcium minerals in your pool water. Levels vary around the country from soft water (50ppm) to hard water(over 300ppm).
For vinyl liner pools the proper range is 125 to 250ppm. Low levels can be bad for vinyl liners and high levels can cause cloudiness and scale.
Copper and iron is a problem in some water. Uncontrolled they can cause staining and discoloration. You must test for these and take the appropriate measures, (adding chemicals), to eliminate copper and iron in a vinyl liner pool.
Chlorine Stabilizer refers to a chemical level that reduces chlorine loss due to UV rays in sunlight by 50% or more. Test the level and add stabilizer as per instructions from the chemical manufacturer. All of the above is important in your pool water care.
