    Chlorine & Bromine

    1. 2 months ago
      Bromine Highly Recommended
      Bromine Tablets are my choice for keeping pool water disinfected. It lasts much longer than chlorine. This will be the third year using this product. Highly recommend 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.

      Quality Bromite Tabs
      Good stuff, quality bromine tabs, well packaged and delivered. I like that these don't seem to have fragrance added - or at least not like other brands I've used. Thanks, very satisfied

      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.

      Awesome product
      We bought the 3 in 1 tabs last year and they worked well. The super multi tabs are even better! Bought them this year and 1 tab a week is keeping our pool clean and sanitized all week!!

      Pool has never been cleaner
      Used other chemicals and a pool cleaner. All has stopped and all I do is add 6-8 tablets every 10 days. I have a 35000 gallon pool.

      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.

      50# buckets and same as the big names is awesome.
      These protect our pool just as well as the big name guys and dissolve just as slowly. From what I can tell Chlorine percentage is the same/same. What I like is the fact I can get a 50# bucket instead of being limited to a 35# bucket. We love these so much we also started to purchased their bromine tabs for our hot tub at our home in Montana where I could finally purchase 25# of bromine at a time. In the Swim has become our go to source for pool and hot tub chemistry supplies. Price is ... read more always awesome. Delivery is quick and product is good quality.

      Best tablets ever
      Love the 3 inch chlorine tablets. They make my pool sparkle all season long. I’ve been buying these for the last 4 years from In the Swim. Quick delivery on all products I’ve ordered from them.

      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 $$$$$

      its ok
      I bought the suppsedly slow dissolving chlorine sticks this spring but they really dont last much long then the 3 inch tabs for the difference in price I will go back to the tabs. In the Swim however as always quick service had product in a couple of days

      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.

      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.

      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.

      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.

      Instant Liquid Chlorine is a great product very ea
      Works great and easy to dispense. Will buy again!

      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!

    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.
