      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.

      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.

      A must have!
      This is a must-have for our pool. I add only 2 (maybe 3) things to my pool. This granular chlorine and PhosFree. Occasionally, basking soda for the pH. But that is it. Iadd it right to the skimmer no mixing that the the filter's job and as long as the pH is in range the chlor is stable for days. Crystal clear for the season!!

      ALGAE GONE
      I started to get Algae on the walls of my pool due to excessive heat and rain - after I used the Algecide - I put three of these Dizap packets in and shocked the sht out of my pool - its crystal clear now!
    3. 2 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.

      Works well
      Great purchase! I used it to shock the pool and the next day all the algae were gone

      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.

      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.

      Cleared Up My Black Algea
      I have had a terrible time with both Black and Yellow Algea all Year. Southern Ca is very hot and intense sunlight seemed to just keek the Algea growing, I tried Bags and Bags of the Di Chlor with no results . I finally bought the 50 LB of HTH and in One Day it cleared it up. Cannot be more happy. Great Price and Product.

      Great value, even better when on sale!
      I have a 60,000 gal in-ground in the middle of the woods in the northeast... constant debris, wildlife, etc. making its way into the pool on a daily basis makes keeping the chemistry balanced and inhibiting algae growth a constant struggle. Previously I was running to the local pool store and picking up liquid chlorine 15 gals at a shot to balance and shock the pool in conjunction with my In The Swim Tri-Chlor tablets in my 2 chlorinators. I decided to give the Calcium Hypochlorite ... read more Sanitizing Granules a shot when I saw the 50# container on a great sale price while reordering my Tri-Chlor tabs. My first shock treatment only took 6# of granules, where as I typically would need 10-15 gallons to reach the same effect. Cost to product ratio was far better with the Granules, plus I can store the 50# much safer in a smaller space than the equivalent in liquids with fewer trips. Not to mention I'm far less likely to get a chemical burn from splashback or accidental spillage with the granules. From my initial experience, I estimate that I will continue this method over liquid chlorine from now on.

      Granny
      Filled the self chlorinater once a week and there would still be little pieces left. It kept the pool nice all summer.

      Best chlorine tabs on the market
      I have used only these tabs for over 10 years, and my pool has never turned green, even through the monsoon storms and extreme high heat in Phoenix, Arizona. I see my friends and families with pools constantly having to deal with pool problems in the summer, and I always recommend In the Swim tabs. If they don't get them, their loss, as there is no easier way to keep your pool sparkling blue!

      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.

      Sure makes it simple!
      I've had a pool for over 20 years and have used every type of tablets or chemical imagined. This tablet ends my search! My pool is CHRYSTAL CLEAR and it takes no effort with these tablets! All year long with a balanced pool.

Took about 3 days total.I use this product everyday and the super pool shock as needed.(have above ground pool).I Love this product.

      Replenished our supply
      In the Swim ships quick. Very competitive prices. This tablets work great at maintaining our chlorine level. We put a tablet in each of the skimmers and the water remains crystal clear. The tablets last about 3 to 4 days (less on real hot summer days). We repurchase these tablets at least every year.

      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.

      Always easy online ordering and even faster delivery

      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.

    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.
