    Affect of cal-hypo and trichlor on levels

    Is there a formula somewhere that indicates what the increase in calcium is per amount of cal-hypo and increase in CYA per amount of trichlor

    1lb of 73% cal-hypo for 21000 gallons of water = x calcium increase
    1lb of trichlor for 21000 gallons of water = x CYA increase

    Saw this posted by Chemgeek (Richard) earlier today:

    The following are chemical facts for some chlorine sources independent of concentration of product and of pool size:

    For every 10 ppm Free Chlorine (FC), Trichlor also increases Cyanuric Acid (CYA) by 6 ppm.
    For every 10 ppm FC, Dichlor also increases CYA by 9 ppm.
    For every 10 ppm FC, Cal-Hypo also increases Calcium Hardness (CH) by 7 ppm.

    You can use the effects of adding chemicals section of my Pool Calculator, towards the bottom, to answer questions like these.
