I shock the pool every Monday and it is spotless!! ### ⭐⭐⭐⭐⭐ Good product *by T***Y on October 5, 2026* We had good luck with this last year so bought it again this year. ### ⭐⭐⭐⭐⭐ Works!!! *by A***L on May 25, 2026* My pool was swamp green when I took the cover off for the season. Then after cleaning it up it was super cloudy. I read about this stuff and decided to try it. I've used it twice and my pool is now crystal clear. I will be buying more and I even told my friends with pools about it 👍🏽 Super easy to use. It's a little expensive but it's worth it because I was spending money on other things that didn't work. ## Frequently Bought Together - Rx Clear Mega Shock | 73% Calcium Hypochlorite | Kills Algae in Swimming Pools | Works As Pool Sanitizer Clarifier and Algicide | One Pound Bags | 48 Pack - Rx Clear 3" Inch Stabilized Chlorine Tablets | 50 Pounds | Individual Chlorinating Tabs for Sanitizing Swimming Pools & Spas | Long Lasting, Slow Dissolving, and UV Protected - Clorox® Pool&Spa™ Swimming Pool Algaecide and Clarifier, Prevents and Treats Pool Algae, Clears Water, 128 Fl Oz (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/44424395-rx-clear-mega-shock-73-calcium-hypochlorite-one-pound-bags](https://www.desertcart.sk/products/44424395-rx-clear-mega-shock-73-calcium-hypochlorite-one-pound-bags) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-13*
