    Generic DPD powder vs. Taylor Brand

    I ran out of DPD powder and came across this listing on Amazon.
    The powder is in pre-measured foil packs. Is there any reason this powder would work any differently with my Taylor R-0871 drops than Taylor brand DPD powder?

    I am considering these for 3 reasons:
    1. They are pre-measured
    2. I don't have to worry about them getting wet
    3. They may last longer since they are sealed

Spill over spa that is NOT heated (heater has been removed) but does have it's own pump and blower for jets which are seldom used. We get live in South Florida where we get a ton of rain and 10 hours of direct sunlight on the pool.

    That's a total chlorine reagent so it likely contains iodide in it to measure both FC and CC together. You would not be able to get separate numbers.

    There may be a pillow packet of FC only DPD powder.

    I'm glad I asked. You are correct, there are others out there. This one is called a "free chlorine reagent". Any thoughts on this one?

    Also, notice that you are limited to a chlorine concentration of 2mg/L (2ppm). So you would need to use multiple pillow packs to get a higher reading.

    I did see that. I guess I will stick with good ole Taylor. Thank you for your input!

    You can certainly try it if you want to experiment. If you wanted to measure between 0-10ppm FC, you'd need to add 5 packets of powder and then titrate.

    Those packets are designed for a Hach colorimeter that is likely used in drinking water analysis so the 2ppm limit is applicable. I do believe they make pillow packs that go higher, but you'd have to search their website to see if you can find the p/n for it.

    The taylor re-agents on amazon frequently go from around $ 30 to $ 18
    for a vial of powder and the drops (combo pack)

    I noticed today it remains $ 18
