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)

Good price and easy to use. It definitely made the water clearer in about 20-24 hours.

I use this in my Titan Wellness 1/4 hp chiller and cold plunge. Works fine!!

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.

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.

good product

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

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.

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.

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.
