Review: We've been using this brand of shock treatment for our above ground pool for several years now. It works great and is affordable for us. Have never had an issue with it except when we forget to put it in the pool lol! We only use this for our pool. We do not use any chlorine tablets or anything else. 1 bag once a week keeps our pool crystal clear, even in our hot humid and sometimes very Iowa climate. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09R82X1S5 | | Brand Name | HTH | | Customer Reviews | 4.7 4.7 out of 5 stars (7,994) | | Item Form | Powder | | Item Weight | 1 Pounds | | UPC | 073187520371 | ## Product Details - **Brand:** HTH - **Item Form:** Powder - **Item Weight:** 1 Pounds - **UPC:** 073187520371 ## Images ![HTH Pool Care Shock Advanced, Swimming Pool Chemical Prevents Bacteria & Algae, Cal Hypo Formula, 1 lb (Pack of 12) - Image 1](https://m.media-amazon.com/images/I/71HW8DNg6EL.jpg) ![HTH Pool Care Shock Advanced, Swimming Pool Chemical Prevents Bacteria & Algae, Cal Hypo Formula, 1 lb (Pack of 12) - Image 2](https://m.media-amazon.com/images/I/8135js+ww6L.jpg) ![HTH Pool Care Shock Advanced, Swimming Pool Chemical Prevents Bacteria & Algae, Cal Hypo Formula, 1 lb (Pack of 12) - Image 3](https://m.media-amazon.com/images/I/71sX3WORZLL.jpg) ![HTH Pool Care Shock Advanced, Swimming Pool Chemical Prevents Bacteria & Algae, Cal Hypo Formula, 1 lb (Pack of 12) - Image 4](https://m.media-amazon.com/images/I/81v6v8TEYIL.jpg) ![HTH Pool Care Shock Advanced, Swimming Pool Chemical Prevents Bacteria & Algae, Cal Hypo Formula, 1 lb (Pack of 12) - Image 5](https://m.media-amazon.com/images/I/71ndcwDEWHL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***T on July 17, 2023* I recently purchased the HTH 52037 Swimming Pool Care Shock Advanced and have been thoroughly impressed with its performance.

I enjoy the smaller bags so I don’t have to haul a big container around. Last a long time as well. Works reliably and consistently. I like using shock because it keeps the CYA levels down since I keep my pool covered. ## Frequently Bought Together - HTH 52037R Pool Care Shock Advanced, Swimming Pool Chemical - Cal Hypo Formula, Prevents Bacteria & Algae, Restores Crystal Clear Water - Shock Treatment, 1lb (12 Pack) - Clorox Pool&Spa XTRABLUE 3” Chlorinating Tablets, Individually Wrapped, Kills Bacteria & Stops Algae (5 LB) - 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.co.za/products/724940539-hth-pool-care-shock-advanced-swimming-pool-chemical-prevents-bacteria](https://www.desertcart.co.za/products/724940539-hth-pool-care-shock-advanced-swimming-pool-chemical-prevents-bacteria) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-23*
