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.

Used for a year and am happy with results, I would recommend. individually wrapped tablets no breakage, well packaged and keeps my pool cleaner than other tabs. I just finished bucket I bought last year for my in-ground Arizona pool and bought my 2nd 25-pound bucket. Buy in winter save a few bucks. saved 20 percent on sale buying in January. Watch your kids around water.

I have been using them for the past 3 years and really never had an issue until I got this delivery. Product works well for me. I put them into a Chlorine feeder and get about 10 Tabs in there that will last 4 weeks. Like I said the product is good and does its job; however, in this batch I just received the Tabs (which are individually wrapped) were broken into several smaller pieces (about 70% of them). Even though, one can still use them in a feeder but they will dissolve quicker and you will have essentially more chlorine in the pool which will dissipate faster as well.

At the time I purchased the price was good and free delivery made it that much better. It is winter and threw six in the pool to try and slowly start increasing the chlorine level in the pool. Tabs are dissolving slowly so I can have a better assessment after the tabs have been in the pool a bit longer.
