  • Great option for Chlorine Pucks
Size: 10 Pound Style: Chlorine Only
I’ve been using these chlorine pucks for a couple of seasons now, and they’ve been a consistent and reliable choice for keeping my pool crystal clear at a great price. The tablets dissolve evenly without leaving behind residue or gritty bits, which helps maintain steady chlorine levels and cuts down on algae growth. I also like that they’re individually wrapped, which makes them cleaner and safer to store between uses. One thing to note is that these are fairly strong, so it’s important to monitor chlorine levels regularly. Overall, these pucks make pool maintenance simple and effective, and I would definitely recommend them to anyone looking to keep their pool water safe and sparkling ... show more

  • They’re dependable, cost-effective, and make pool upkeep a breeze. Highly recommended!
Size: 25 Pound Style: Chlorine Only
I've been using In The Swim's 3 Inch Stabilized Chlorine Tablets for many seasons now, and they’ve quickly become a staple in my pool maintenance routine. These tablets are effective, easy to use, and provide consistent sanitation without the hassle of daily monitoring. Pros: Long-Lasting Formula: Each tablet dissolves slowly and steadily, which keeps the chlorine levels in my pool stable for days. I only need to check and refill the floater or chlorinator once or twice a week. Stabilized for UV Protection: Because they’re stabilized, they hold up well under the sun without burning off too quickly, which saves me both time and money on frequent dosing. Clean and Convenient Packaging: The tablets come individually wrapped and in a sturdy bucket that’s easy to seal and store. Reliable Sanitization: I’ve had zero issues with algae or cloudy water since switching to these tablets. They really keep the water crystal clear and safe. Cons: Strong Odor: As expected with chlorine, the smell is strong when opening the bucket—so make sure you’re in a well-ventilated area. Not Ideal for Smaller Pools: These 3-inch tablets may be too much for very small pools or spas unless you break them up, which can be messy. Final Verdict: If you own a medium to large-size pool and want an efficient, low-maintenance chlorine solution, In The Swim's 3-inch tablets are a fantastic choice. They’re dependable, cost-effective, and make pool upkeep a breeze. Highly recommended! ... show more

  • Good chlorine pucks to last thru the summer
Size: 50 Pound Style: Chlorine Only
These are a good deal and last me the majority of the summer. They work well in my chlorinated keeping my water clean and sanitary. I just load up the chlorinated with as many that will fit.

  • Good bargain but absolutely hate the pucks being individually wrapped.
Size: 50 Pound Style: Chlorine Only
Worked well. Price was quite good. Some pucks broken but not an issue. My biggest complaint (and the one star off) is the individual wrapping. This was not helpful. It's just a pain to have to open each individual puck. It doesn't save my skin from chlorine since the bucket has powder and I wind up fumbling with and cutting open the packaging anyway. Besides which it's just more plastic to blow around and clean up. If they're not wrapped I can just reach in with a baggie and grab what I need. Please drop the wrapping. ... show more

  • Good value
Size: 50 Pound Style: Chlorine Only
Why did you pick this product vs others?: I buy two of these to get me through a season and they’re great to use, dissolve completely, handle easily and don’t seem to upset water chemistry at all.

  • Works great!
Size: 5 Pound Style: Chlorine Only
Works great. I like that each tablet is sealed in the bucket. All tablets were whole and not crumbled like other products I’ve bought. Will continue to buy!
