With HTH 3” Chlorine Tabs Advanced, you're all clear for fun! Review: Works fantastic!! - These pucks are fantastic!! I don’t know what this brand does differently than other brands- but it works! We have had an above ground pool for 5 years now. The first couple years we used liquid chlorine and constantly had to battle with algae and burn off in the hotter months of summer. We switched to pucks during year 3, but the prior brand we were using had the same burn off issues. We swapped to this brand last year. Since using this brand our pool has been at consistent chlorine levels in the ideal range, without the burn off. Our pool has never been this clear!! We typically buy this size container, and break the pucks in half. We pop half a puck in the skimmer basket every day and a half, and the chlorine levels stay consistent. These don’t dissolve super quickly like other brands, but instead provide even chlorine coverage. I highly recommend this specific brand- we will never use anything else from here on out. For reference I have the Bestway platinum series 12’ x 20’. We also have a permanent skimmer basket (purchased separately) attached.

Hard to Open. *by D***O on 6 March 2026* The only downside is getting these out of the plastic case even after the initial opening of product. Once it's closed it's still very hard to open. ## Frequently Bought Together - HTH 42052 Swimming Pool Care 3" Chlorine Tabs Advanced, Swimming Pool Chlorinating Sanitizer, 5lb - HTH 52037 Swimming Pool Care Shock Advanced, Swimming Pool Chemical, Cal Hypo Formula (12 Pack) - ARM & HAMMER Clear Balance Swimming Pool Alkalinity pH Maintenance Tablets, White, 1 Pack, 24 Count --- ## 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/453578272-hth-pool-care-3-chlorine-tabs-advanced-swimming-pool-chlorinating](https://www.desertcart.pt/products/453578272-hth-pool-care-3-chlorine-tabs-advanced-swimming-pool-chlorinating) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-23*
