    Small white 'pimples" on resurfaced pool wall

    About two years ago, I had my pool compeltely resurfaced. Recently I have noticed several small white 'pimples' forming on the pool wall. When I scratched a few of them it appears something is seeping through the pool wall and hardening into a white crystaline substance.....Any idea what this might be?

    Is that possibly calcium scale? Can you scrub it off? How well have you kept your water balanced?

    Yes, that's it exactly...thanks.... The first nodules were scrapped off bt mne over a week ago and are still gone. I did notice a couple more this morning and scrapped them off as well.
    Is there a chemical ratio that is best for this condition?
