  • Great tablets at great price
Style: Chlorine Only Size: 50 Pound
These tablets keep our pool chlorinated without over-stabilizing. The price is a little better than my local pool store, which makes this a really convenient option. One warning - this is a large bucket that holds a lot of chlorine. If you’re storing it somewhere warm, you will get gas build up that can be dangerous to breathe when you open the bucket. Make sure to air it out outside and step back. ... show more

  • Better than the local store pucks
Style: Chlorine Only Size: 10 Pound
I just recently went back to the pucks. I tried to manage my pool with liquid only but this FL sun would burn it off too quick.I first bought 3 pucks from my local Pinch a Penny and they dissolved completely in one week but the pool kept chlorine strong all week and looked great so I knew I needed to keep the pucks. At $7 each, that's insane so before I bought them in bulk from the pool store, I decided to try these. I bought a 10lb bucket. Arrived in perfect condition and individually wrapped. A week and a half later, my pool is balanced, looks amazing and the pucks are still more than half way so however they make these allows them to not dissolve as quickly as the pool store. I am very happy with my purchase and when I finish the 10lb bucket, I will get the largest one they have to save. Update: just finished my 10 pound bucket and ordered the 50 pound bucket. Still very satisfied. I need 3 pucks and they last about a week and a half before I need 3 more. Update: 50 lb container just arrived. Top 10 pucks are broken in half. The box was heavy and when in the box, you can’t use the handle which makes it tough to transport. They probably threw the box around. Hopefully not many more are broken. Removed one star for delivery. ... show more

  • Good deal!
Style: Chlorine Only Size: 50 Pound
This is a good product at a decent price. I really like that all the tablets are individually wrapped. It does help to mitigate the chlorine fumes coming out of the bucket when you open it. I've read reviews complaining about the tablets all being broken upon receipt. In fact some of mine were broken but the wrapping was still intact so the entire content did make it into my dispenser. I'm not fussing about what likely may have happened in shipping. Most of the few that were broken had a crack right down the middle and near perfectly in half. I routinely break tablets in half to get more precise about what I'm adding based on test results and I think this is helping me control the CYA content too. I find these already broken tablets more of a help than a hindrance. I just use the half tablet and re-wrap the remaining half for later use. Nothing lost. Recommended! Enjoy! ... show more

  • Keeping the pH level in the ideal range will make your chlorine work more effectively
Style: Chlorine Only Size: 10 Pound
I recently decided to tackle the responsibility of maintaining my own pool, and boy, did it become an adventure. I tried a few different chlorine tablets to keep my pool clean and clear, but nothing seemed to work well enough. My water was turning all shades of green, and I was getting pretty frustrated. That's when I stumbled upon the "In The Swim 3 Inch Stabilized Chlorine Tablets," and boy, what a difference they've made! These chlorine tablets are like magic for my pool. They keep bacteria, algae, and other unwanted guests at bay, giving me clean and clear water all season long. The best part? They dissolve slowly, so I can avoid inconsistent chlorination and the need for frequent adjustments. I've tried other tablets that dissolved too quickly, and they just didn't do the job like these bad boys do. One thing I absolutely love about these tablets is that they're individually wrapped, making them super convenient to use. I just toss one in my floating dispenser, and it takes care of the rest. No more measuring or messing around with loose tablets. It's a pool owner's dream come true! Tip/Trick: Easy pH Level Monitoring Now, maintaining a pool requires more than just chlorine tablets. You'll need to keep an eye on the pH level too. Here's a little trick I've learned to make it easier: Invest in some pH test strips or a digital water test kit. Test your pool water regularly (I do it weekly), especially after heavy use, rain, or warm temperatures. Keeping the pH level in the ideal range will make your chlorine work more effectively and save you money on chemicals in the long run. Happy swimming! ... show more
