    • Great Stabilized Chlorine. Best Price!
Size: 50 Pound Style: Chlorine Only
The In The Swim 3 Inch Stabilized Chlorine Tablets are hands down the best way to keep a pool clean and clear. The tablets dissolve evenly and last a long time, which makes pool maintenance so much easier. I’ve noticed consistent chlorine levels and crystal-clear water since switching to these. The quality is excellent—no crumbling or excess residue like with some other brands. They fit perfectly in my floater and skimmer, and they provide steady sanitizing power even in the hottest months. On top of that, In The Swim is the best place to buy chlorine. The price is fair, the shipping is fast, and the packaging is secure. It’s convenient knowing I can count on them every season without hassle. If you want reliable, long-lasting chlorine tablets and a trustworthy source to buy from, these are the ones to get. ... show more

    • GREAT PRICE FOR THE QUANTITY YOU RECEIVE!!
Size: 10 Pound Style: Chlorine Only
These chlorine tablets have been great. I have bought these multiple times on here. The quantity that you receive, and the individual wrapped tablets are great for the price. I had shopped around locally, and you will pay more for this quantity and brand. They keep the water very clear, and sanitized with the proper regular maintenance, of course. They work well with any above ground pool and are a great fit for any pool. I will continue to purchase these as long as they have them on here. ... show more
