High CYA content mitigates chlorine's sanitizing properties, right? At the same time, does high CYA mitigate chlorine's negatives, e.g., if I shock a low CYA pool with 25 ppm chlorine, I might damage a vinyl liner or swim suits. Would I face the same kind of risks shocking to 25 ppm when my CYA content is well in excess of 100?
