    Help with Testing Shock Levels of Chlorine

    Hello TFP.

    Hey Guys need Help, SWG Took a dump on me and I now have Algae forming.

    Need some assistance with Testing Higher Chlorine Levels, (Trying to SLAM the pool)

    The only "DECENT" test kit I could get in this part of Canada was the LaMotte Pool Manager 3368
    as seen here: http://eduardojamesblog.blogspot.ca/201 ... mming.html

    Problem being is the DPD 1 and DPD 3 Chlorine Test's only go up to 3.0.

    I have called all over this town and cannot find any test kits that test much higher. (7 being the max)

    I'm wondering if a can dilute the Pool water with distilled water and multiply the results.
    The Test requires 5ml of Pool water to one DPD tablet

    I need to SLAM around 18 according to my CYA Levels and the Pool Calculator.

    Welcome to the forum.

    Dilution will work but you dilute your precision by about the same amount. It will work for you to maintain at or reasonably close to SLAM level FC but it will not work to perform OCLT.....there is not enough precison.

    I'm wondering if I can put together a FAS-DPD Kit by just ordering what I need here? (they have an office in my town)

    http://www.acapulcopools.com/products/f ... order-form

    Seems like I'd Need:

    R-0870I DPD Reagent Powder
    R-0871C FAS-DPD Titrating Reagent

    and
    R-0003C DPD #3 Reagent to CC Test

    Anything else? What Size Test Tube?

    Those are the reagents you need.
    You need something to dip the powder with. A popsicle stick works in a pinch.
    You need something to measure and hold 10ml of water and allow you to swirl it around.

    Thank you Very Much. I have a few Test Tubes 10ml and larger that came with the LaMotte Pool Manger Kit (Not a Cheap kit here in Canada)

    Roughly how much power is used for this test?

    Probably the smallest amount you can get on the tip of a popsicle stick. About half a bb's worth.
