Great cold plunge water treatment!
This product is the best that I have used for keeping my cold plunge water clean and odor free. I use it once a week in conjunction with my filter for crystal clear water each time.

Great for our cold plunge
This product works great! Iโve been using it in my cold plunge and it really helps keep the water fresh, clean, clear, with no odor. Super easy to use just add it in weekly and it does the job. I love that itโs a 3-in-1 treatment, which saves time and makes maintenance simple. Definitely recommend if you want to keep your plunge water looking and feeling great! Came wrapped up securely no leaks. Good price. Size last us all month in our cold plunge.

Keeps our ice bath clean!
We use this weekly in our ice bath, between cleanings and it keeps the water looking great. It lasts a long time, you just need to put in a little a week. There is no odor and its easy to use.

Unknown Chemical Soup
It works. But they are hiding the formula under the guise of "proprietary blend" on the SDS which is fine but if I'm bathing in this chemical blend every day I'd atleast like to be informed about what's in the product so I'm not poisoning myself every day.

Not enough on its own and caused problems after a few days
I spent 40 euro on this thinking it would keep my cold plunge clean and safe. At first the water looked clear but after three days I started to notice itching on my skin every time I got out. That is when I learned this product is only a clarifier and softener. It does not sanitize the water. The label says you still need to buy a separate sanitizer such as chlorine or bromine. So on top of the 40 euro already spent I now have to spend more money elsewhere to make the plunge usable. It might help with water clarity but it is not a full solution and it gave me skin irritation after a short time. If you want a safe cold plunge you will need to add a real sanitizer.
