The influence of adverse pool water chemistry on the. vinyl was assessed through observation of changes in vinyl. colour, weight, dimensions, tensile strength and elongation. (stretching). The laboratory studies revealed that the factors most. affecting vinyl liners are high chlorine concentration, and.
1 The chlorine can degrade the pool liner. Also, run the pump for several hours after adding chlorine. Misuse of chlorine, particularly using high concentrations, is a major cause of vinyl deterioration.  Keep your filtration system well maintained so that it can properly remove debris and other impurities.
