      Much Better than Granular Chlorine
      I had used granular chlorine for years up purple stains (copper?) started forming on the pool walls. Then I switched to calcium hypochlorite. It is much more effective, and no copper stains or algae in two years. It is a bit more expensive, but it works. One minor problem: Unlike granular chlorine, you have to be home to sign for the delivery of calcium hypochlorite.

      Chlorine Sticks
      I highly recommend the use of In The Swim's Chlorine Sticks. They are the best, most long lasting, effective and inexpensive I have used in the 38 years I have had my pool. You cant go wrong with these chlorine sticks. My pool looks great.

      very good product
      I have been using In The Swim chlorine sticks for about 15 years now along with ITS pool shock and Algaecide 60 plus in my pool. With Texas summers having 100° + temperatures, the combination of these products keeps my pool clean and clear. I maintain my pool on a year round basis with these products and don't have to do spring startup or winterizing and have never had any green water.

      Easy. Once a week in the dispenser and I’m done
      Used these last year. Kept my pool almost 100% clean. My pool Gets full sum so only had a tad bit of algee in the hottest days. Other than that. I add 3 tabs a week and it’s crystal clear.

      Worth the money
      First time ever owning a pool. A friend of mine referred me to in the swim. I chanced it by making the purchase but am so thankful. My water is crystal clear and this makes everything easy. These tabs make me thankful for owning the pool. I refer everyone to these tabs.

      Pool has never been cleaner
      Used other chemicals and a pool cleaner. All has stopped and all I do is add 6-8 tablets every 10 days. I have a 35000 gallon pool.

      Works great!
      I have always used chlorine in my fiberglass pool and chlorine shock and it faded my blue pool to almost white. I had to repainted my pool this year because of the paint chipping up and didn't want to have the paint color fade again. I started using non chlorine shock and bromine tablets and it works great! No more chlorine smell, red eyes, and faded everything ( clothes, pool floats, pool paint). I am glad I switched!

      No more chlorine for me
      I use Bromine in my above ground swimming pool. It works great and i dont have any problems with algae. I put it in a floating feeder and it slowly dissolves. Lasts a long time. It is not harsh to your skin and eyes. My nephew breaks out from chlorine when i switch to bromine he hasnt broke out since. Its a little expensive for how much you get but worth the performance of the product. Dont breath in the dust from it will get you. A lot of pool stores look at you crazy when you tell them you use ... read more in your pool. They dont know much about it. Its great.

      Bromine Highly Recommended
      Bromine Tablets are my choice for keeping pool water disinfected. It lasts much longer than chlorine. This will be the third year using this product. Highly recommend it.

      Liquid Chlorine No More
      I have been using Liquid Chlorine from In The Swim for several years. The 5 gallon liquid chlorine started feeling heavier and heavier. This is a great (and lighter) replacement. Works just as well.

      Convenience is key for OPTIMUM POOL TIME!
      I appreciate the packaging of all the individually wrapped tablets in the heavy duty bucket! I sit them beside my tote of other chemicals and supplies by my pool, have a pair of scissors handy at all times, and am ready to add a tablet to the pool 'floatie'. THANK YOU! Each tablet lasts about 4 or 5 days!

      50# buckets and same as the big names is awesome.
      These protect our pool just as well as the big name guys and dissolve just as slowly. From what I can tell Chlorine percentage is the same/same. What I like is the fact I can get a 50# bucket instead of being limited to a 35# bucket. We love these so much we also started to purchased their bromine tabs for our hot tub at our home in Montana where I could finally purchase 25# of bromine at a time. In the Swim has become our go to source for pool and hot tub chemistry supplies. Price is ... read more always awesome. Delivery is quick and product is good quality.

      3" tabs
      I've used these 3" tabs for many seasons now and they work great. I have a 45k gal pool and use about 4 tabs in the skimmer basket per week. Thats it. Easy.

      Great product
      This is the same chlorine I use from our pool supply store. It works great and is really less expensive. Its a plus that it is delivered right to my door.

      Excellent product
      I have had great results with this product. Well worth the money.
    3. 10 years ago
      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.

      Di Zap pool shock
      I have my packages of shock delivered right to my door don't have to run to pool store. My pool stays crystal clear and I have recommended to all my friends never have cloudy water again.
    2. 3 years ago
      Bought to help in the management of our salt system pool after having the same recommended by the pool supply where a water sample was taken which is about 29 miles one way.

      CRYSTAL CLEAR SPARKLY pool, better than Calpo!
      We switched from super-shock to Dichlor for our 18x33' above ground pool because our well water is extremely hard, and this brand of it is awesome! 99% sodium Dichlor clears our pool SO FAST! Calpo took WEEKS to clear a green pool. With di-zap, we have a crystal clear pool in ONE day. Beautiful, clear, SPARKLING. Amazing. Plus it helps keep our stabilizer levels up... another problem we were having. And it dissolves quickly & completely - no liner bleaching. Love di-zap from In The Swim!

    In The Swim Knowledge Pool: Pool Chlorine & Bromine

    In The Swim's Dr. Pool

    America's Most Popular Pool Chlorine!

    According to the CDC, free chlorine kills most bacteria in less than a minute if concentrations and pH level are maintained properly. Swimming pool chlorine is the most widely accepted pool sanitizer available, and for over 75 years, pool chlorine has been the most popular method to disinfect and sanitize pool water. Pool bromine can be used as an alternative pool water treatment, yet chlorine tablets and granular chlorine remain America's first choice for maintaining clean and clear pool water. 


    Pool Chlorine or Pool Bromine?

    The general rule is that bromine is more often used in spas and hot tubs, and chlorine is more often used in pools. Although they are close cousins and adjacent to each other on the Periodic Table, bromine and chlorine have distinct differences, and unique benefits to offer pool owners. 

    Chlorine and Bromine

    • - Bromine can be reactivated to reduce cost.
    • - Bromine is more stable in hot water, to provide longer lasting sanitation, even during full use.
    • - Bromine is more stable in a wider pH range, remains strong under rapid pH swings.
    • - Bromine has less odor in the water, and less irritation to skin and hair.

     

    • - Chlorine is the most economical way to sanitize a pool.
    • - Chlorine is sun-stabilized in our 1" or 3" slow dissolve Trichlor tablets and 8 oz. sticks.
    • - Chlorine tablets and sticks dissolve rapidly enough to treat larger pools effectively.
    • - Chlorine granules react instantly for rapid super-chlorination or shock treatments.

    Swimming Pool Chlorine Types and Use

    In The Swim pool chlorine dissolves fast and almost instantly begins to sanitize your pool water. In The Swim 3 Inch Chlorine Tablets are 8 oz. stabilized pool tablets, and are also available as a 0.5 oz. pellet, in our 1 Inch Chlorine Tablets, for very small or very large pools. In The Swim 8 oz. Slow Dissolving Chlorine Sticks work fast and last longer. Our 3-inch Super Multi-Tabs are unique chlorine tabs with stabilizer, algaecide and clarifier added. Sticks or tablets can be used in chlorine floaters, or place the pucks into an in-line or off-line chlorine feeder, to provide a daily sanitizer level that is consistent and constant. 

    In The Swim granular chlorine like the economical Cal-Hypo granular chlorine and stabilized Di-Chlor chlorine granules are both available loose in buckets and also sold in 1-pound bags, as Pool Shock, Super Shock and Di-Zap. Pre-dissolve chlorine granules into a large bucket of water for vinyl pools, or sprinkle the powder directly into concrete pools, spas and fountains to maintain sanitizer levels, to raise low levels rapidly, or to super-chlorinate the pool. Granular chlorine is used regularly to quickly kill algae and bacteria, and to oxidize microscopic particles and contaminants in the water.

    Pool Chlorine Chemistry

    Chloramines form when a chlorine molecule has combined with ammonia or nitrogen to produce the familiar scent often associated with swimming pools - that’s not the smell of free chlorine, but of combined chlorine. As chloramines build up they reduce the effectiveness of your sanitizer. When the chloramine level (Total - Free Chlorine) is greater than 0.3 ppm, (TC-FC=CC), this is time to add pool shock to your pool to remove the chloramines. 

    UV rays from the sun breakdown chlorine which makes your sanitizer less effective. Although In The Swim pool chlorine tablets are stabilized, it takes some time for a residual to build up. Pool stabilizer (aka conditioner) contains cyanuric acid to reduce sunlight degradation. It’s like sunscreen for your chlorine, and will save you money in the long run. 

    The pH of your pool water has a large effect on the efficacy or potency of your chlorine. In addition to maintaining stabilizer levels in the 30-50 ppm range, keeping a close eye on pH will reduce your chlorine costs, and also help ensure clean and clear pool water. At a high-pH level of 8.2, over half (+50%) of your chlorine is wasted. Pool chlorine works best at low pH ranges of 7.2-7.4, and becomes less active in higher pH pool water. 

    Bromine for Swimming Pools

    In The Swim Bromine Tablets are slow-dissolving by nature, and can take longer to build up a residual, although bromides can be added to quickly boost levels. Bromine is also un-stabilized, so it does not stand up well to bright sunlight. However, bromine tablets are popular for indoor pools or heavily shaded outdoor pools. Bromine pools have a softer smell of pool bromine, and can re-activate bromides into bromine, simply by shocking the pool (with chlorine!). 

    To use bromine in a pool, you will need to have a bromide ion 'bank' built up, or a preexisting level of bromide ions (the reduced form of bromine). Many bromine users add Brom Booster to raise levels quickly when converting a pool to bromine. Then you simply use the bromine tabs in a brominator (bromine floaters are not as effective). In The Swim Bromine is a BDCMH formula that stands up to sun degradation better than other bromine tablets, and contain no cyanuric acid.
