This product works just as well then another brand I was using, and it's a little easier on the wallet.

Works Great for Hot Tub!!

Non-Chlorine Shock works Amazing in our Hot Tub. We add just a little to the water if it starts to get a little cloudy and it clears it right up! This is something you definitely want to keep on hand if you have a Hot Tub!
