      Won't switch back!
      I ALWAYS use liquid chlorine and would pick it up with my groceries while at my local Wal-Mart. The huge bottles took up most of my cart not to mention mixing with groceries never set right with me. I saw this product online and with the free shipping thought, why not. When I first received the package, I thought something was wrong because the box was so small. The bottles were really little which really worried me. I can't believe how well they work. One of these little bottles works better ... read more and lasts longer then a whole gallon jug of the other stuff I used to buy. It dissolves quickly and does not leave a powder residue on the bottom of the pool floor. A little more expensive then what I was paying before but I use less and it gets delivered right to my door. So worth it!

      Super product!
      I have used bromine for over twenty years because it is far superior to chlorine that has a strong odor, dull water and is prone to algae outbreaks. This bromine is pre measured in plastic bags that while they tend to be fragile, allows me to quickly and easily dispense a measured portion without lifting a fifty pound bucket or handling an exposed product. This product gives me sparkling crystal water. It is delivered to my door at a far more reasonable price than the local pool shop. It is ... read more gentle on the pool and equipment. The last paint lasted 14 years without blistering or peeling.

      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.

      Bromine
      the little plastic bags disintegrate in the bucket and the tiny pieces of plastic get in the brominator & clog the valves -- never used to come in the "convenient bags" was always just tabs in bucket. don't know what to do now. Maybe empty all bags on first arrival if they are intact then??

      Best value and best product out there
      15 tabs last all week in my 25,000 gallon inground pool. And it keep the chlorine on the high side as opposed to the low. Great life on this product too. Haven’t noticed any deterioration in its strength after it winters over either. GREAT PRODUCT. We love it in the Northeast!

      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!

      Good product but falls a bit short
      Although it’s a good product don’t depend on it to work as your algaeside eveb though it says it will. If conditions are right you will still get algae in your pool. I recommend the super shock once a week in conjunction with this for a crystal clear pool

      In the Swim 3" Chlorine Tabs
      The 3" chlorine tabs work just fine. Free shipping and fast delivery a decided plus. Each tablet is in a sealed plastic bag which I like, but now I know why. The tablets are fairly soft. They break easily and don't last as long as say Regal chlorine, whose tabs are like rocks. Overall good deal though - good price, free and fast shipping, and friendly 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!

      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.

      Works Well So Far
      I bought 50 lbs of the chlorine pill shaped tablets, and they lasted for over a season now, we only needed to purchase a 25 lb bucket to get us through thus season. Pool has remained clean and clear using these tablets, very effective!

    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.
