    Chlorine & Bromine

    1. 7 years ago
      Bromine
      When product arrives, most of the bags are half full of bromine POWDER which is not how it is dispensed in the brominator. So for the price it is not good. I could pay about $15 more at a local store and the tablets are solid and have much less powder residue.

      Best Chemical for your pool
      Bromine is actually much better for your pool than Chlorine. It is rather costly but In the Swim's cost for Bromine is the best price out of all the Pool supply shops around. I shopped around and found this to be very true. Not only is Bromine good for your skin its easy on the eyes versis the sting from Chlorine. Its also good on your hair, it doesn't dry your hair out or cause your dye job to turn green. I highly recommend the chemical if you can afford it.

      Just the right size
      This arrived on time, and did not expect them to be packaged in 1# bags inside the bucket. But this is fantastic. Don't have to try and lift the whole pail and dump them in. Take out a 1# bag open and dump in brominator. I will be saving money by being able to better control how much I am adding each time.

      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.

      So easy to maintain pool now!
      I discovered these multi tabs this year and have used them from the time of start up. My pool has never looked so good or been so easy to maintain. I take pool water to be tested once a month and have only had to adjust the alkalinity one time(after a heavy rain). Other then that I have only used these tabs and all pool chemistry has been perfect! Fun to own a pool again.

      THE BEST
      I USED TO THINK CHLORINE WAS CHLORINE; it's all the same. I have been using the super multi tabs for a few yrs now. Will never use anything else. I never have problems with algae or spring start ups. I used to spend days in the spring getting pool back in shape. We live in dusty Arizona & those monsoon dust storms we get can play havoc on a pool. Best chlorine!

      Very useful product.
      The granular chloride has been very handy to have. It’s easy to use and increases choline levels in the pool fairly quickly.

      chlorine
      Works just like the very expensive chlorine other stores sell.

      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.

      Great product
      I have been using "In the Swims" chlorine sticks for over 20 years. Probably longer. I float the sticks in the floater and it works well.

      My pool is too small to use the skimmer sticks
      Last year I purchased skimmer sticks from my pool man and thought they were working wonderfully. This year pool man never returned my calls so I purchased from you. I found out that my stabilizer was off the charts due to the pool being too small for the skimmer sticks. I think they are great for a large pool. I have used products from In the Swim in the past when I had much larger pools. Too bad. Now I need to see if I can sell my 10 lb bucket minus 1 stick.....

      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.

      Great Chlorine Product!
      I bought this product and so glad I did. It works great! I use it with Yellow Out in my pool and it works wonders. I recommend it to all.

      In The Swim is the best value for pool chemicals..
      Good deal for the price. This is the first time I have bought the Calcium hypochlorite from this site but it is a good deal compared to pool stores and other online sites.

      Great Product
      Great product. Does not make the pool cloudy. We use this as shock for our pool. It was recommended from our pool guy.

      Amazingly effective!
      I am in complete disbelief of how effective this product is. I was foolishly using Walmart brand shock for years ( simply because it was convenient) I live in Florida and from April through October I typically use 3 to 4 bags a week. I ran the numbers and decided to buy this product. I have literally only shocked my pool twice in the last six weeks! My biggest problem is that I ordered a huge bucket expecting to go through it as quickly as the Walmart brand. It’ll take me years to go through ... read more this! Highly recommend !

      Great price for a great product
      Before buying chlorine tabs I did some research. Several sites had "In the Swim" as the best or second best of the chlorine tablets. What I bought is 50# for the cost of what pool stores around Phx wanted for 40#. And....they are individually wrapped.
    2. 2 weeks ago
      Works well. Some broken but ITS replaced them.
      Tablets work well. After getting halfway through the bucket, I realized most of the rest were broken up pretty bad and wouldn't work right in the feeder. I contacted In the Swim and they sent out replacement tablets. Good customer service.

      Best Chlorine tablets in the market.
      We always buy this chlorine, one time when we forgot to reorder we shopped locally and bought HTH. HTH is terrible and our pool quickly lost its Christal clear quality. We immediately went back to In The Swim Chlorine Tablets and we are back to pristine water. This is by far the best and most economical Chlorine tablets in the market. Thank you!

    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.
