    Chlorine & Bromine

    1. 1 month ago
      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”

      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.

      A Must have for the hot summer months
      This product will clear out the nastiest water. In the south we get tropical showers that will require a lot of chlorine. This product is wonderful and gets the job done.

      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!

      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.

      Worth the money
      First time ever owning a pool. A friend of mine referred me to in the swim. I chanced it by making the purchase but am so thankful. My water is crystal clear and this makes everything easy. These tabs make me thankful for owning the pool. I refer everyone to these tabs.

      WOW THIS REALLY WORKS
      Was having trouble getting our PH regulated and constantly having to put in stabilizer, we also were constantly Having a black residue that would appear after adding acid, bleach , stabilizer, baking soda! We live in the Panhandle of Florida! I also have an Ionizer (from In The Swimm from day one of putting in pool in 2006, liner type). I purchased this Multi tab! And a float dispenser. ( Love the tip over when you need to add more tabs style!!). We put 3 tabs in the dispense ( 13,000 gal ... read more pool). Over night the PH, Stablizer and every thing Was starting to move in a positive level!! We checked our levels every late afternoon the first 3-4 days! WOW THESE TABS WORKED!! Pool is perfectly balanced in all test strips !!! Have not had to add any tabs to dispenser ( we even had to close the dispenser a little as to not release as much ). So there you save $$ also!! Purchase these Tabs!!! You will be amazed!! We also shut our Ionizer off for the first few days and just now turned on to the lowest of lowest setting !! $$$ saved there ( will not have to replace the chamber as often!! Fantastic product!! So worth the extra $$ !! Because we have not had to add any chemicals to our pool going on 3 weeks!!! We even went out of town for a week and the pool is still stable and Beutiful ! YES, yes 5 plus stars on these multi tabs!!! .

      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.

      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!

      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.

      Great product
      Easy to purchase and product was shipped immediately. Tablets are much easier on pool and equipment.

      Indoor pool so cal hypo is the way to go for us. One tab will typically go about three days. It does require a constant eye on your pH as it will raise pH levels in the pool. Recommend for indoor pools where you don't get direct sunlight and thus don't need cyneric acid.

      Not anti-scale
      I've been using these for about a year now in my well chlorinator, and I have to descale it weekly.

      Awesome
      I was using htc 3 in 1 tabs along with in the swims 5 in 1 and I thought my water was clear. I ran out of the htcs and bought these. Im still using them along with the 5 in 1s and wow! My pool water looks amazing! Won't use anything else but these again.

      Great product, great price great company!
      For over 16 years we've been using In The Swim 3" chlorine tablets. They do not leave a residue around the edge of the pool like other brands. They dissolve predictably and safely. I've never had an issue. It's not often you find a truly reliable and effective product. We've happily use many other items in their catalogue. Oh, their shipping? Spot on supplies arrive the NEXT business day! I highly recommend this company and products.

      Great Bang for the Buck
      The 50-lb. container was boxed and conveniently delivered to our front door. The tablets are individually wrapped. Thus, you are not hit with a strong chlorine odor each time you open the container. Having used the tablets for a few weeks, we have found them to be slow dissolving and highly effective in maintaining proper chlorine levels. Most importantly, you cannot beat the price. You will pay 50% more for a 50-lb. container elsewhere.

      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.

      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.

      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.

      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.

    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.
