3in1 Cold Plunge Water Treatment, Weekly Natural Ice Plunge Stabilizer & Clarifier, Harsh Chemical Free, Fight Scum & Odors for Clear Waters - Pure55 Made in The USA (32 Fl Oz)

Works great!

Purchased a cold plunge for my wife’s birthday this summer. We tried to get by with using some shock from our pool and then we tried to use some of the spa specific chemicals. I feel like most people would try and use what the have immediate access to and it worked ok. We finally looked for something designed specifically for cold water and came across this. We placed the cold plunge in our workout room and I always felt like there was a really slight musk smell in the room. After using this the water remained clear and I never caught the faint smell again.

It helped but water still cloudy

We have a cold plunge that is outdoors AND used daily by 4 people…2 are kids who definitely like the novelty, but are not the best at keeping leaves and grass off their feet! It is very difficult for our family to keep water clean for more than a few days. I am still tinkering with the best timing on application for our situation, but so far this has allowed us to 4x how long we use the water by just following the instructions on the bottle. At that rate I am saving a few hundred gallons a month of water as well as 6 times doing a scrub down each month!!!! Solid product with great value!!

So far, so good I’ve been using it for a few months, I change out the filters in my cold plunge and then add some of this product and it keeps the water crystal clear, but it is still very cold, lol

This stuff completely plugs up your water filter! It’s like pouring a bottle of glue into your cold plunge. I don’t know how they can sell this. Have to drain my cold plunge to get rid of this weird impenetrable film this creates on my water filter.

This water treatment works wonderfully! Once added, there’s no detectable smell, which is a big thing for me and my wife. I couldn't stand it if I smelled like a pool or something after and was forced to take multiple showers or something. It keeps the water fresh, clean, and crystal clear, making maintenance a breeze. I’ve been impressed with how effective it is at maintaining that clean and refreshing feel in the water. If you’re looking for a reliable solution to keep your cold plunge water in top condition, I highly recommend this product! EDIT: I'm lowering the star rating to 3 as I had been assuming it was a higher concentration. The liquid smells like it might have some iso-alcohol, and who knows exactly what else. My gripe, while relatively small, is that the directions say to use 1/4 of the bottle at a time. My cold plunge being on the larger side, I know I'll need to use it, but I've used other treatments that only require a very small amount, like a cap full. Those bottles really last. I wish this was just a higher concentration so I wouldn't have to buy so often. Also, a treatment-to-water ratio makes more sense to me for the directions. Also, I’ve found another product that can do the same or similar job and only need a capful every week. And it wasn’t really more expensive but on a per/use basis, this ends up being much more pricey

After having struggled with water clarity for over a year in my tub, this stuff seems to do the trick in keeping it clean and clear.. I add 1oz a week along with 2oz of hydrogen peroxide and my water has been clear for almost 2 months now.
