    Chlorine & Bromine

      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.

      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.

      The BEST!
      I tried this last season when there was a special on it. You get what you pay for . BUY THIS. Dump in and walk away every week. Clear Water, no headaches. Compliments on the pool clarity to follow. Excellent product well with the added $$. Thanks again intheswim for keeping pool maintenance simple.

      Works great!
      We openned our pool this year without knowing our cover had small holes in it. Needless to say, first time we had openned the pool with problems. I ordered this product and 2 applications brought the wster back to crystal clear!

      best results I've ever had
      I have found that I am not useing as much shock and back-up that I had in the past. I have told a number of my friends about this web site and how good the price's are compared to others that I have checked out plus the place that I have used for a number of years. I am now getting ready to make another order on other items that I need because the price's are right and as tight as my money is now, every penny counts. If the other items work as well as the Chlorine sticks do, I'll keep coming ... read more back for other items.

      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.

      Quick Delivery and Packaging
      First time user to In the Swim. I placed an order at noon on Monday, and the Chlorine tablets were delivered by 1:00 PM the next day. In the 10 pound container, the tablets were packaged into 1 pound segments. Definitely saved money vs. a pool store.

      Extremely fast and efficient delivery
      I recently purchased 1" Chlorine Tabs and Non-Chlorinated Shock. Great fast delivery, chlorine as always wrapped in plastic bags, so very little crushing/chlorine dust (due to badly-packaged tabs, crushed in packing or delivery) AND easier to dispense into my chlorinator. Thanks, ITS.

      Caution!
      When using "Stabilized" Chlorine 3" tabs remember that you're adding cyanuric acid (54% by wt.). If you load up with too many tabs and increase the water flow to the chlorinator you may get too much acid which inhibits the effectiveness of the chlorine.

      Great quality chlorine tablets

      Easy install
      Very thin for the price. I just put the cover on, so I can't really comment as to how it's going to hold up. It was very easy to install. Comes with a cable and a ratchet to attach the cover to your pool. I have an above ground 15' easy setup pool. I ordered the 18' cover because when I winterize my pool the water level is lower than 6 inches so it was recommended to order up a size and it worked perfectly. I also ordered the clips to go along with it, but I didn't end up needing those. Much ... read more simpler to install than the cover that came with the pool.

      Value on Granular Chlorine

      So far, so good
      Had too much CYA from “stabilized chlorine” and needed to lower, this product gave me chlorine without CYA, and I’ve had seen my CYA lowering since using it (have had to pump pool few times due to rain) but I use about 6-8oz every other day for 20k gallons, and have had no issues. Was worried about price paid and thought of it not lasting long, however, I’ve hardly put a dent in the bucket, and probably could make a full season last from one bucket at the rate I’m using currently

      exactly what I needed
      I had a to treat my pool for white water mold several times of the last 3 years which required multiple applications of high amounts chlorine based shock. The chlorine shock that I used was stabilized and the end result included my pool water registering a high level of stabilizer. I needed to find a chlorine product that did not include a stabilizer and this product was EXACTLY what I needed.

      Excellent product
      Great product for quick clorine adjustments. I use it in combination of float with 3 in tablets.

      Great Dissolving Qualities
      In The Swim granular chlorine is the only one we will use in our pool. Coupled with occasional Super Pool Shock treatments throughout the season, the pool stays crystal clear. A great combination, and one that we have counted on for over ten years.

      GOOD SERVICE
      I have been operating a pool for about four years. In the past I would pick up chemicals at pool supply stores or large discount stores. I always had issues finding what I needed when I needed it or paying too much also everyone's product worked reacted differently. In the swim has been a great solution to many problems. I am busy and generally order my chemicals at night after the kids go to bed, I have found that having in the swim deliver the chemicals to my front door is by far the ... read more easiest way to take care of my 10,000 Gallon pool. I have consistent chemicals that work great! My pool is now always crystal clear and it is easy to maintain the balance.

      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!

      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.

      Your money's worth!
      I've used these tablets for years. They're strong but also slow dissolving. So it takes a long time to go through a bucket. I feel I'm getting my money's worth.

    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.
