Good for reducing chloramines. I shock my hot tub after every use, so we use a lot of this stuff. The 5 lb tub makes it far more convenient. ### ⭐⭐⭐⭐⭐ Great price *by K***5 on January 6, 2026* Great price ### ⭐⭐⭐⭐⭐ GREAT for Resolving Cloudy Water - Bulk Purchase *by S***L on January 11, 2026* 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. ## Frequently Bought Together - Leisure Time RENU5 Renew Non-Chorine Shock, 5 lbs - Leisure Time E5 Spa 56 Chlorinating Granules for Spas and Hot Tubs, 5-Pounds (Packaging may vary) - LEISURE TIME 22339A Spa Up Balancer for Hot Tubs, 2 lbs --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/3986483-leisure-time-spa-renu5-shock-renew-non-chlorine-shock-treatment](https://www.desertcart.hr/products/3986483-leisure-time-spa-renu5-shock-renew-non-chlorine-shock-treatment) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
