Easy to use. ### ⭐⭐⭐⭐⭐ Good pool shock, no surprises *by G***S on July 19, 2025* Works just like you'd expect granular calcium hypochlorite to work. Effective shock, no clumping, and relatively easy-to-open pouches. It dissolves relatively quickly in a warm pool, but does require a bit of brushing. (If you've never used a calcium-based pool shock before, do your homework. It can bring up the hardness of the water, and if you already have hard water, it can have side-effects. Otherwise, it's a great, shelf-stable alternative to sodium hypochlorite.) ## Frequently Bought Together - Doheny's Super Pool Shock | Pro-Grade Chlorine Shock, Quick-Dissolving, Fast-Acting 68% Cal-Hypo Granular Pool Shock | 6 x 1lb Bags, Proudly Made in The USA - In The Swim 3 Inch Stabilized Chlorine Tablets for Sanitizing Swimming Pools - Individually Wrapped, Slow Dissolving - 90% Available Chlorine - Tri-Chlor - 10 Pounds - In The Swim Super Algaecide for Above Ground or Inground Swimming Pools – Low Odor, Non-Foaming Preventative for Yellow/Mustard Algae in Swimming Pools - 7.1% Chelated Copper – 1 Quart --- ## 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.pt/products/221894123-dohenys-super-pool-shock-pro-grade-chlorine-shock-quick-dissolving](https://www.desertcart.pt/products/221894123-dohenys-super-pool-shock-pro-grade-chlorine-shock-quick-dissolving) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
