    Calcium hardness and swimmer comfort

    I've read on this forum that CH levels (unless too high) are not so important for vinyl pools. Having said that, is there an optimal range for swimmer comfort? If levels are too low does the water feel too 'soft'? If levels are too high does the water feel too 'hard'? CH in my pool is 100 ppm.

    There are small differences in "water feel", but most people don't notice them. Softer water is generally considered better feeling, but again the difference is very small.
