Take a water sample by plunging a plastic cup upside down to elbow depth and then turning it over to let it fill. Take the sample where your shallow end meets the slope to the deep end if you have one and away from the returns.
Fill the test block to the 10 ml level and add 2 scoops of powder ..1 works but they say 2. Swirl it around and if there is chlorine present it will turn bright pink. Now take the 0871 and add a drop at a time while swirling in-between until the liquid turns clear. If it's just a little pink add one more and you will see when it's perfectly clear. Count the drops and multiply by .5 (or divide by two of course) and that's your FC Free chlorine. Add five drops of the 0003 reagent and if it turns pink again you have combined chlorine (bad). If it is pink you then again add drops of the 0871 and count until clear ... that's how much CC is present and must be added to the FC to get your TC Total chlorine level.
