Can someone remind me how to test chlorine when your chlorine level is high as to not use so much of the RO871. Sorry but I seem to remember there was a way where you only use half as much of the ro871 but I searched everywhere and can't find it

You can use a 5 ml sample of water, one scoop of powder, and each drop of reagent to clear equals 1 ppm FC.

Do not use that for an OCLT or daily maintenance.
