    I use this alone, without a pump or filter and it keeps my ice bath water fresh and clean

    5.0 out of 5 stars Keeps water clear
    Reviewed in the United States on November 2, 2024
    I ordered this product because I started cold plunging last year and I finally upgraded to using a stock tank. I will admit I have our pool filter hooked up but when I add this product is makes the water crystal clear. We have very hard water, we have a well, and this product clears the water up almost instantly. I put it in at night and by morning it’s looks even clearer than it did the night before- which I didn’t think was possible.

    The media could not be loaded.
    This conditioner is highly concentrated so if like me you have a smaller ice bath, this could be the best bang for your buck but I'm not a doctor. I've been using this for several months and I have to change my water very little. After the initial treatment, just an ounce a week keeps the water clear and clean instead of murky and slimy to the touch from natural body oils.

    5.0 out of 5 stars Great for a cold plunge
    Reviewed in the United States on December 21, 2024
    I ordered this for use on my back deck cold plunge this winter (see pic). So far, it's worked great. The water has stayed clean and clear (looking), and doesn't appear to smell at all. Now, I can't claim that I "know" it works (as I can't test the water), but my skin has been doing fine with it.

    Only used a few times in my cold plunge. No smell and seems to have kept water fresh

    5.0 out of 5 stars Seemed to stabilize the water
    Reviewed in the United States on November 21, 2024
    Ordered this water stabilizer to use in my cold plunge ice bath and clean the water. I will admit I modified my ice bath with a small sand pool filter to help circulate and clean the water. However, the filter can only do so much to get the dissolved solids and other foreign materials out. This clarifier made the water look clean and feel refreshing again. This clarifier is easy to use and a little bit goes a long way.

    Overall, a very good addition to my cold plunge setup.

    1.0 out of 5 stars Not for still water ice baths
    Reviewed in the United States on December 25, 2024
    Bought it under the impression that it was for an inflatable cold plunge and when it finally got all the way to Hawaii the instructions read that it was for a plunge with a pump. Needless to say it hasn’t been effective at all.
