    FAS-DPD test

    I've been diluting my pool water with 50% chlorine free water so I could save my R-0871. Is that just as accurate as using straight pool water???

    Thanks

    No, using dilution is less accurate. Depending on what you are doing, it might be good enough. It is good enough for determining shock level. It is not good enough for doing an overnight FC loss test.

    Thanks Jason. Guess I better quit doing that. I'm trying to tweak my SWG. Done with shocking
