    SWCG Chlorine Balance Question

    So I thought I saw this answered before, but couldn't find and and can't remember the answer if I did read it...

    When I have CYA of 80 in my salt pool, why does poolcalculator still recommend only 3ppm of FC? That makes me a bit nervous! I'm keeping it at 6 right now, but would not mind lowering if it is safe.

    The superchlorination that occurs in the cell makes up for the reduced activity of the chlorine in the water at the higher CYA.

    With a CYA of 80 it recommends 4 ppm FC, not 3. It is consistent with the Chlorine / CYA Chart for SWG pools.
