    first one is no and the second kalwasser is used to raise KH so yes it would go up

    so the question is why have you been dosing kalwasser ?

    Ph tends to swing, but dKH only declines as it is adsorbed.

    Sounds like you are overdosing...best reduce mate

    RO will not lower PH as its only replacing evaporated water

    the only reason to use kalk is to raise KH / calcium

    you can dose bicarbonate of soda to bring up KH and keep it satble needs to be at 8.3 to be in ballacne with calc
