Leisure Time RENU5, Spa RENU5 Shock Renew Non-Chlorine Shock Treatment

Just as advertised, no problems Work great

The company from which I purchased our hot tub told me when the water gets cloudy, that chlorine is hard on the system and that I should use an oxidizer. For whatever reason, cloudy water is not uncommon in my hot tub despite regular maintenance. I found I was going through the Clorox bottle of oxidizer (this same stuff) too quickly for approx $10 a bottle, especially when an application can be 2 - 6 oz! That along with the other chemicals I use on a regular basis (clarifier and stain/scale), required some strategizing, to buy in bulk. This is how I landed on this brand/bottle and it's been working well. I HIGHLY recommend it if you find yourself using an oxidizer fairly frequently. And don't believe Clorox's assertion for their product that it takes 30 minutes to clear up. It does not. It can take 24 - 48 hours to clear up, as my retailer even said.

We only use Leisure time spa products and chemicals. We do like this shock and use it exclusively. The price is competitive and although it took a lot longer than expected or promised, it did finally arrive. It dissolves easily. it is easy to use and we do like it for our hot tub.

Does the job, 2nd time buying

We have used it in our hot tub for years.

Order was received quickly and was exactly what we ordered.

Came highly recommended for my 2000 gallon Swim Spa to use in place of a chlorine shock which kept bring my CYA to high than safe levels... Only problem is I ordered it and it showed next day along with my 3 bottle of chlorine and they shipped USPS and it changed to 4 day delivery while the same brand chlorine did come next day. So I didn't get a chance to use it on my normal cleaning cycle till next week.....

I've been using the Renu and Reserve combo in my hot tub for over a decade now, and honestly, I won’t use anything else. It’s just that good. Renu has a kind of sand-like texture, while Reserve is a liquid, and together they keep my water crystal clear with minimal effort. You just pour it in—no complicated measuring, no constant testing—and it does its thing. Super easy. What really sets this duo apart is the scent. There’s no harsh chemical smell like you get with other products. When I lift the cover, I’m greeted by clean, clear water and a soft, pleasant aroma that makes the whole hot tub experience feel a little more spa-like. If you want something effective, low-maintenance, and actually enjoyable to use, I can’t recommend Renu and Reserve enough. Total game changer.
