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

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 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.

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

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.
