      As good as any pool store
      I have bought Chlorine from my local pool store before and just thought of trying In Swim. The quality looks as good as my local store and price is almost half.

      Best deal and high chlorine percentage
      I bought a 50# bucket of 3inch chlorine tablets. Great value, quick delivery and high percentage chlorine tablets. I've noticed some big box stores tablets are <90% chlorine. These say 98.6% Trichloro-S-Triasinetrione. Not sure if I'm comparing apples to apples but these seem to work better than the big box brands.

      Long lasting
      I bought a smaller bucket to try and really liked the results. Somehow my water looked so much better. I wish I had bought the product sooner. I ordered a big bucket so I will have it on hand when I open my pool next season.

      Did what they said they will
      I have not found a product that works as well for the same price. Each stick is individually wrapped so when you open up the bucket you are not COMPLETELY knocked over by the fumes. I also live in a moist climate so they do not deteriorate. I use the sticks in an in-line chlorinator and once you have your chlorine levels set, it's easy to keep the desired levels. In the Swim ships quickly and my order has always been correct. Their prices are much more competive than I can get from my local stores.

      I ABSOLUTELY Love this stuff!
      I have owned a pool for 30 years and have never had an easier opening and summer than 2007. I put it in last fall before closing the pool and again upon opening. In the spring, I had the CLEAREST water ever in 30 years. Quickest opening I ever did. My chlorine use was literally cut in half this year and I used ABSOLUTELY NO ALGAECIDE this year. My friends who did not use this had all kinds of algae problems this year. Me... NONE!!! I will never be without it again. It is AMAZING stuff. And I am ... read more a hard person to convince of something. Try it. You will be GRATEFUL you did!

      No sludge here!
      I just tried this product for the first time. I had read a few other comments saying the product was difficult to pour and left sludge in the containter. Those comments almost kept me from buying this product since convenience was the main point of buying the liquid stabilizer. I used one gallon this morning and it poured easily (about the consistency of a latex house paint). I added some pool water to the empty bottle and the bottle rinsed clean easily. No problems at all with dispensing. I'll ... read more retest the water this evening after circulating for the day to see if I need to add more.

      Great chemicals
      I love these. I buy the 50 pound bucket & the tablets are wrapped in smaller bags within the bucket. It makes handling & storage much easier. We use these to refill our automatic chlorinator. I haven't had any problems since we starting filling it ourselves with these 1 inch tablets. We use to get alge from waiting for the chlorine cartridges to empty. Now I can just add more & not worry.

      chlorine tablets - 3"
      In the swim makes pool maintainence a breeze; if I run out of the tablets, I can literally get a 50 pound box the next day! they come neatly packaged and easy to use and store. The price is so cheap I will never buy them any other place but in the swim. I buy all my pool supplies from in the swim.

      Good value
      These one-inch tab are not easy to find. The ones from In The Swim are a good value for the money. Convenient size container.

      Excellent Product
      I tried the instant chlorine and it works great. I put in my pool every eight days and the water is clean and a nice blue. I like it better then the liquid chlorine due to the fact that the containers always leek when I buy them at the hardware store.

      Great Product
      I love the fact that this product works so well with no fuss and muss, You dump the appropriate amount into the skimmer basket and let your filter do the rest. I have no problem maintaining the proper chlorine level and the filter does all the work. If you do run into any algae growth, a heavier dose of this product works well to kill it. No wasting money on costly algaecides. Reccomended doses for weekly shock are on the container too. I also love the safety lid. I have used many that are just ... read more so hard to open, this one just has you squeeze the tab and rotate. No more fighting the lid just to get to the chemical.

      I was amazed
      This product amazed me - we had been using a lesser product and we had to mix it in water, pour it in through the filter and it STILL came out the spouts and settled on the floor of the pool. This product is simple to use - just sprinkle it around the deep end and watch as it quickly disolves prior to hitting the bottom of the pool - it immediately raises the chlorine level!

      This is the greatest chlorine I have found. It controls not only the chlorine but also neutralizes the acid. It totally dissolves so there are no granules sitting on the bottom of your pool. Love the stuff.

      SAVE MONEY!
      My stabilizer tests were consistent but just slightly low. After boosting to the correct levels my chlorine use...during the SUMMER is HALF what I was using in the winter! Great product, easy to use, great price!

      Disolving product
      Cyanuric acid is a white powder or granular product which is usually added to the pool water through the skimmer. Backwash the pool filter first, then remove the pump basket and restart the system on "filter" and add Cyanuric acid slowly to the skimmer closest to the pump. Stabilizer dissolves very slowly so we add it to the skimmer to allow the product to reach the pool filter where it can dissolve slowly over time. Do not backwash the pool filter for a few days after adding stabilizer. It ... read more needs this time to dissolve. Cyanuric acid has a low pH. Adjust the pH level of the pool water to 7.5 - 7.8 once the stabilizer has fully dissolved or after a couple of days.

      does the job
      Purchased product and it did exactly what it was supose to do. The recommended dose put my stabilizer level exactly where it needed to be, and two weeks later, has maintained its level. Awesome product!

    More On Pool Chlorine and Bromine

    Pool chlorine and bromine are the most used chemicals to sanitize your pool water. In the Swim carries multiple forms and quantities of both swimming pool chlorine and bromine to suit your budget and pool's demands. Pool chlorine and bromine is what keeps your pool water crystal clear and free of harmful bacteria. Pool chlorine and bromine are both available in many different forms like our best-selling 3 inch chlorine tablets to 1 inch tablets, chlorine sticks, granular chlorine and liquid chlorine. The method in which you introduce pool chlorine and bromine to your swimming pool will determine the best form of pool chlorine and bromine for your inground or above ground swimming pool. Many pool owners prefer chlorine tablets since they are low maintenance and easy to use in floating chlorine dispensers and chemical feeders. Liquid chlorine is a simple one step process of dumping the chlorine sanitizer straight into the pool or introduce it through the filter and pump. Another popular pool sanitizer is bromine. Bromine can take the place of chlorine for those sensitive to the smell of chlorine. Bromine is also better for swimmers with sensitive skin. The one drawback most pool owners acknowledge in using bromine is that bromine must be introduced to the pool through a chemical feeder since it dissolves very slowly. No matter what method or form of pool chlorine and bromine is best for you, the variety of shapes and quantities are perfect for owners of small pools to managers of large public pools. In the Swim is a leader in pool chlorine and bromine, and our pool experts are happy to help with any questions you have regarding our pool chlorine and bromine or any of In the Swim’s pool supplies.
