    i use about a cup of sodium bisulphite to a half gallon of water..it
    works beautifully and quickly as long as the pool ph down is at
    least 93% sodium bisulphite..if its less than that buy another brand.
    If you want a stripping strength solution use more...basically it's
    the same as using sparex..and by the way, if you have a bag, not a
    can of sparex for non-ferrous metals according to krohn, the makers,
    "it never goes bad", the cans however, tend to rust, thus adding
    oxides to the pickle from the beginning...and the tech guy at krohn
    has always been a jerk when i've called with specific questions..like
    i'm trying to steal his formula..please!but you are better off with
    product that has no oxides to start with as their old cans did react
    with the sparex.Pool ph down is by far cheaper and the same active
    ingredient.
