5 Things to Know About Preventing Pool Liner Fading

Imbalanced water chemistry is the main cause of fading High chlorine and low pH attack the liner from the inside, making it brittle and faded faster than UV alone.

Maintain pH between 7.2 and 7.6 This prevents chemical bleaching of the liner pattern.

Keep alkalinity at 80–120 ppm Proper alkalinity stabilizes pH and protects the liner.

Chlorine must stay within recommended levels Excess chlorine accelerates fading regardless of covers.

A solar cover helps but cannot fix bad chemistry It blocks UV when the pool is unused, but if chemistry is off, no cover will save the liner.
