    Calcium Hardness and Vinyl Pool

    From reading Pool School and seaching previous posts, it seems that CH is not a concern for a vinyl pool.
    My CH is 103 and the pool company said it should be 175 before closing. Of course this came with the sales pitch of a 25lb bucket of calcium chloride.

    Just checking with the more knowledgeable, but I think my 103 is just fine.
    Correct?

    CH of around 100 is fine for vinyl.

    You can have too much CH in any pool....over 400+......you don't have that so no worries.

    Thanks.
    I figured it was just a sales attempt or ignorance.
