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)

Delivered as promised. Works great in my cold plunge. Highly recommend. Just set cold plunge for the season. Add the bio ouster, water was crystal clear within about an hour

Super easy to use. There is no odor. I think its very important to use to keep your chiller clean.

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.

What are the mystery ingredients? Tears from cage free chickens and tortured turkeys? Reclaimed Data Center waste water? Toilet bowl cleaner? Who knows, but it does seem to kill anything in my cold plunge water and keep it clear and tinted toilet bowl blue for much longer than filter and ozone alone. Been using for a year and on my second bottle. Seems safe-ish: skin hasn’t blistered off and my hair hasn’t fallen out or turned blue. Still I wonder what’s in the mix with every plunge. Probably nothing, but wish they would be as transparent on the chemical mix as they claim your water will become. Trust us, we are a chemical company.

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.

By far the best for my cold plunge. I have tried them all and this one lasts and just a little bit goes a long way.

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.

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.

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.
