    calcium hardness up

    i have a vinyl pool and 2 bottles of calcium hardness up left over from previous owner. it seems like there was a bit used from one bottle.

    would i ever have any use for these or will they just take space in my shed? my logic says i should throw/give it away.

    There is never any need to raise CH in a vinyl liner pool.
