Easy and simple to use, straight forward instructions and dosing, great value as once initial dose is done periodically topping up required, good size last and water clarity and smell is great

This product works great! I’ve 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 it’s 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.

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.

I started using this in my cold plunge, and within just a few hours the water was noticeably clearer. I use one capful per week, and it does a great job keeping the water clean and fresh. If you don’t want to invest in a filter, this is a simple and affordable option to help maintain your cold plunge.

Been using this for a month, seems to work better than most.
