  • Blue and clear pool
Size: 25 Pound Style: Chlorine Only
Great product even better price. As long as the price stays reasonable I will continue to buy this chlorine for my pool I love the fact that the tablets come individually packed. They stay whole and are never broken. My pool has been clear and blue all through the spring no algae ever with the In the Swim Tablets. ... show more

  • 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

  • Good deal !
Size: 25 Pound Style: Chlorine Only
These tablets are great and the only thing to note is that when you open the bucket they are all individually wrapped , so it does take a little more time removing the plastic, but they were all in tack and not busted up . Will buy again !

  • In The Swim 3 Inch Stabilized Chlorine Tablets
Size: 50 Pound Style: Chlorine Only
I've used this before and the product works - the tabs are individually wrapped, which is kind of a pain but the ones that come broken [it happens] are contained and not all at the bottom of the bucket. Quick ship. I'll buy from here again. WAY less expensive than my pool store, for sure.

Great product for the price. Shipping was very fast. About half the cost of tabs for me locally. They last a pretty long time.
