    Chlorine & Bromine

      "Liquid" chlorine
      Very convenient in size. It is not liquid chlorine. It is a powder that makes chlorine when added to the pool.

      CL2 in BIG bucket
      Great big bucket of CL2, and it comes with a blue scoop w measuring markings with is perfect to assist with getting the amount you need. Just know the percentage of CL2 in the ingredients listing so you know the strength of the CL2 you purchased. I was aware of the strength at purchase.

      Great product delivery is fast
      The 50 pound bucket is easy to open true I used a screw driver the first time now it opens like it is supposed to and it latches securely. It is best to dissolve it in a bucket and then decant it. There will be undissolved product in the bottom. Repeat until all the granules are dissolved. The reason it doesn’t dissolve all at once is because it creates a super saturated solution. It is all trichlor there is no “carrier”

      Works as expected. Fast delivery.
      Received as expected. It is a bit cumbersome to move around such a large pail (50lb), but the price is why I went with it. I use it as pool shock for my 45,000 gal in ground and it will last a while.

      YOU HAVE TO TRY IT TO BELIEVE IT--IT WORKS
      I have been using this product for several years and believe me it works great. Just look at all of the reviews, mostly all fives. Yes I wish it was cheaper, but it works great. It's just like a great steak, if it taste great and tender I don't mind paying a little more for it. The only thing I can tell you is to buy the 9lb bucket and try it and you too will be hooked on it.

      Excellent tabs to use!
      These tabs make keeping the pool clean an easy task. With the exception of removing falling leaves, these tabs keep my pool clean and sparkling. I don't even measure ph levels anymore-these tabs do it all. I just wish the cost was a little kinder, but it's worth it.

      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!

      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.

      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 features
      Much cheaper per lb than buying small 5 # containers at the local store. There are small plastic bags holding the tablets. Much easier to work with than trying to dump out of other containers I used to purchase.

      Use these in my self modified pool frog cartridges. Allows me save on cost of having to purchase new cartridges.

      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!

      Great chlorine price, great product
      Love that the tablets are large enough to fit my floater and they are single wrapped! I had no algae this summer. Replaced chlorine tablets every 7 days.

      Good Stuff
      Fast delivery to the door, nice! Keep having to turn down my chlorinator so that is a good thing as well. Water is clear and sparkling as long as I stay up on the shocking every couple of weeks and keep the pecans and pecan leaves out of the pool. 95-100 degree temps tend to exacerbate unwanted growth of unwanteds but the tabs are doing their job. So far the Cyanuric level has not been a problem. Been a month, so happy!!

      Swimming pools and more
      In the Swim is the place to go for maintaining one's swimming pool and or septic system. Their pricing, convenience of shipping, and availability not to mention the coupons are just some of the reasons we have been their customer for years.

      Shock it!
      This is the best Shock product that I have used in our in-ground pool
    2. 4 weeks ago
      Makes pool maintenance so easy
      I alternate this shock with regular shock 1-2x/week - occasionally less often if nothing is happening. Pool needs very little chlorine. After struggling through trying many different products to maintain balance when we first got the pool, now we're down to a super simple routine - practically maintenance free! Big fan!

      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.

    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.
