Bio Ouster 3in1 Weekly Cold Plunge Water Treatment - Cleaner, Clarifier, and Softener for Cold Plunge and Ice Bath - Water Stabilizer for Fresh, Crystal Clear Water - Made in USA (32oz)

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.

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

Does exactly what it says. I add a few oz’s to my cold plunge weekly and water is always nice and clean

I think the key is if you have a pump to run it from time to time. I've gone as long as a month before changing the water. Not that it ever go cloudy, but thinking - okay, it is time for fresh water. I get some crunch like stuff on the bottom, but I think that is just due to the hard water in my city. With this chemical there's no more cloudiness. Water is always clear. Will continue to use it.

Keep water clean and clear

awesome product I cannot believe how much longer my water lasted by adding this product. Everything was crystal clear for months. I will definitely buy again when I'm out of this product. Should last me a long time.

Left a build up on my ice bath tub.

seems to do its job , ph levels stayed consistant

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

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.
