Review: Easy simple water treatment and clarity - 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
Review: 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.
