Title: They’re dependable, cost-effective, and make pool upkeep a breeze. Highly recommended!
Review: 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!

Title: Healthy Pool
Review: I use “In the Swim” 3 inch tablets to help keep my pool water balanced through a chlorine float. I use 3 tablets at a time in the float (4 when the weather is over 100 degrees) and replace as they shrink. Depending on the weather, the large bucket of tablets last me at least a year.

Title: Very pleased with product.
Review: Wow really amazed, how long a tablet has lasted. I put 1 tablet in skimmer on Wednesday night, it is Saturday morning and still have a piece a little bigger than an inch. And water is much clearer. It was getting cloudy prior to adding tablet.The top is a little tricky to open at first, but once open once it isn’t a problem. Love that the lid locks back, instead of just clicking back on.Really like that each tablet is individually wrapped.Functions as described, clears water and easy to handle tablets with being individually wrapped.Definitely recommend, will purchase again.

Title: Good bargain but absolutely hate the pucks being individually wrapped.
Review: 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.
