    What does Calcium Hardness really do?

Why even waste your time with these people unless you are trying to educate them?
    Agree. Which is more corrosive, ocean (salt) water or fresh water?
    12,000 gal concrete IG, Sta-Rite MaxEGlas 3/4 HP pump (230v 8A) Sta Rite System 3 Filter, Hayward Ultra crawler.
    10% Bleach bottles on bottom of pool. AquaChek 7 Strips, Clorox SmartStrips, Bakersfield City water.

    Welcome to TFP,

    In answering this specifically on its own, Sea Water without question. Whether it's in relation to corrosion by being more conductive in a metallic system, or deposited on things it can corrode it's Sea Water by far. Is there something more specific you're inquiring about?
