Proper water chemistry matters more than covers for fading.

Yes, but here’s the thing: intense sun isn’t the only culprit. Imbalanced water chemistry — especially high chlorine and low pH — attacks the liner from the inside out, making it brittle and faded faster than UV alone ever could.

The real fix is maintaining balanced pH (7.2–7.6), alkalinity (80–120 ppm), and keeping chlorine within recommended levels. That prevents chemical “bleaching” of the liner pattern. A solar cover helps block UV when the pool isn’t in use, and quality liners with UV inhibitors are worth the extra upfront cost. But if your chemistry is off, no cover will save you.

You can slow fading by about 80% with good water care. The sun is the enemy, but bad chemistry is the saboteur.
