  • They’re dependable, cost-effective, and make pool upkeep a breeze. Highly recommended!
Style: Chlorine Only Size: 25 Pound
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

  • 20 tablets in 10lb bucket
Style: Chlorine Only Size: 10 Pound
All tablets were individually wrapped and none were broken. For others who are curious, there were 20 tablets in this 10lb bucket. I haven't used the tablets yet to confirm effectiveness but judging by the potent smell and solid state, they don't appear to be deteriorated old stock.

  • Healthy Pool
Style: Chlorine Only Size: 50 Pound
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.

  • Good bargain but absolutely hate the pucks being individually wrapped.
Style: Chlorine Only Size: 50 Pound
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 chlorine pucks to last thru the summer
Style: Chlorine Only Size: 50 Pound
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.

  • Very pleased with product.
Style: Chlorine Only Size: 10 Pound
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. ... show more

  • Good value
Style: Chlorine Only Size: 50 Pound
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.
