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

      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.

      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.

      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.

      Chlorine
      Always easy online ordering and even faster delivery

      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.

      Fantastic purchase
      I ordered the 1" tablets from In The Swim, and am now using less tablets, my pool water is alway good when checked and I saved $$$$$

      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.

      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.

      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!

      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.

      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!

      Super Service, Super product
      I ordered 50lbs of granular chlorine one morning and it was delivered to my doorstep the next afternoon. Not only is the service great, its the best product I have ever used and we have been using granular chlorine since 1963. This product is stabilized and leaves no residue. All this means no algae and no problems. I have to laugh at friends who struggle with green scum for weeks. Mine clears up in 1 day. LOL.

      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.

      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.

      Works great
      I have been using this product for 3 weeks now and my water has never been clearer. Very happy so far.
    2. 10 months ago
      I used this product last summer and had the least pool maintenance in 30 years. My pool water remained clean and shiny throughout the summer.

      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!

      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.

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

      I LOVE THIS LITTLE BOTTLE
      AT FIRST I WAS SKEPTICAL ABOUT THIS POWDERED INSTANT LIQUID -- I NORMALLY BUY THE LIQUID CHLORINE TO ADD TO MY POOL, SO AT FIRST WHEN I OPEN THIS BOTTLE AND SAW IT WAS GRANULAR I THOUGHT WHY WOULD THEY CALL THIS "INSTANT LIQUID CHLORINE" BUT I HAD NO CHOICE AT THE MOMENT AND USED IT AFTER A LARGE POOL PARTY AND BOY WAS I PLEASANTLY SURPRISED...IT MADE MY POOL CRYSTAL CLEAR AND I'VE HAD TO USE SO LITTLE TO MAINTAIN ON A WEEKLY BASIS...SO I LOVE THAT I'M ACTUALLY SAVING MONEY. THANKS 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.
