32 Oz Shock Oxidizer for Hot Tubs, Spa Chlorine-Free Shock Oxidizer, Suitable for All Spa & Hot Tubs Types

Great product! I have an above ground spa that I have nurtured for the last 17 years. It runs like a champ when used. Recently I noticed yellowing of the water. I immediately put in an above-normal amount of chlorinating granules to correct the issue. Next day, I still saw some yellowing. So I bought this product, used it the other day and my spa water is now crystal clear! Amazing results! Great price also!

Helps keep our spa clean does not stink like a lot of others do worth the buy

Works great, dissolves quickly

I have been using this for a couple years now. It was the cheapest I could find online and I have never had a problem. A cap full after every use is all I have needed. My spa gets used a couple time a week.

I love this product for my eco spa, works great!

This is as good as any of the name brand oxidizers and it costs much less.

Works great

I waited awhile to do my review on this to see how this worked. I had a spa that became slimy. Yuck! Didn’t know what to do so I started my research on Amazon. I am so happy I got this shock. I first used a sponge to wipe the insides of the sides of the tub with the water in it and washed and changed filters a few times. Used this shock about five times while continuing to clean the filter and believe it or not-it worked! Water is crystal clear. Now I use the shock about once a week to maintain and it has been great for weeks. Very happy with this purchase! I will definitely buy this again and again!!
