I love this shock for our swimspa. The 6 lbs. last about 3 months for us and keeps our swimspa crystal clear. I use just a tablespoon or two after every swim and it works wonders on keeping our water fresh and clear. Read more
Works well and costs about half as much on here as it does in a hot tub store or at lowes. Read more
This shock is fantastic, and I was able to get it on Amazon for much less than in stores. I use it for my hot tub, and having a container this size means I don’t have to rush out for more in an emergency. It has a slightly strong smell, but once I sprinkle it in, the chlorine levels stay stable and my hot tub stays crystal clear—no fussing with multiple chemicals. Great quality and highly effective. Highly recommend! Read more
The media could not be loaded. Such a great product. I only gave 4 stars because it leaves this crusty residue that takes some scrubbing to remove but this stuff cleared up my spa very nicely. We had to do 2 shocks over 2 days but worked great. Read more
Quick delivery, great product Read more
A capful of this after each use, combined with my frogger system, keeps my hot tub clear and clean. Super easy to open and a great value for the money. I even use some in my pool from time to time to clear up algae. Read more
This product performed exceptionally well. I had been using another product together with test strips, and regular filter changes and had developed a persistent slightly cloudy condition. After applying this product my hot tub water was again crystal clear the very next day, and has remained so for 30 days, with just 1 additional treatment after 2 weeks. Also, no complaints from my wife about strong Chlorine smell or eye burning. Very satisfied customer. Thanks Read more
I have owned hot tubs for over 30 years now, and this is the best shock ever ! It clears the water and odors without creating clumps and a film of oils on the surface. It also doesn't lead to foaming. I highly recommend it ! Worth the price !!! Read more
