    CC test

    It seems that my water always turns a very faint pink after adding reagent R0003 that clears after adding one drop of R0871. Does this mean I always have a very low level of CC, or is this normal?

    Re: CC test

    Our pools are constantly transitioning FC to CC and waiting for the sun to oxidize it. That faint appearance might also vary at different times of day, so I see nothing to be concerned about. We treat CC readings at 0.5 or less as zero, so you are just fine.

    I get a very faint pink from time to time as well. Usually when I've left my solar cover on for days at a time with little sun directly hitting the water to help burn off CCs.

    The only thing I would add is ensure you never drop below the recommended FC level for your CYA level. Otherwise... Well just don't let it happen!..
