Re: how many gallons of 6% liquid bleach one 3" chlorine tab
I set the pool volume to 10,000 gallons, though it doesn't matter what one uses since the result will be a relative one. I then set the chlorine source in the pull-down menu in the FC section to "trichlor", set the Now to 0 and adjusted the Target number until the Trichlor weight became 8.0 ounces which is the weight of a typical 3" tab/puck (they can vary from 6 to 8 ounces). The FC Target it took to make that happen is 5.5 ppm. I then made sure the bleach percentage was set to 6% and saw that this was equivalent to 114 fluid ounces of 6% bleach. This number is a little different than the previous post because that post assumed a 7 ounce puck weight -- if you use 4.8 ppm FC as the Target, then you'll see a Trichlor weight of 7.0 ounces and a bleach amount of 100 fluid ounces.
