    Chlorine & Bromine

    1. 4 years ago
      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 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.

      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.

      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.

      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.

      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!

      Multi-Tablets are very effective
      Tablets are very effective and provide for essential carefree pool maintenance. Pool is crystal clear, free from algae and inviting for swimming. Would recommend them to a friend.

      The BEST!
      I tried this last season when there was a special on it. You get what you pay for . BUY THIS. Dump in and walk away every week. Clear Water, no headaches. Compliments on the pool clarity to follow. Excellent product well with the added $$. Thanks again intheswim for keeping pool maintenance simple.

      Great Shock for Price and Excellent Pool Water
      Best Shock I've ever used in 25 years. Very efficient results with less use than in the past with lithium shock

      Great product! Bad container design!
      The product itself is fantastic! It's nice not having to deal with opening 1 lb bags, one by one. However, the lid refused to come off, literally. We actually ended up having to take a hatchet to the top to create a hole get the granules out. Luckily we had an extra empty large container that our 3" chlorine tablets came in, so it ended up dumping the product in that container instead. ITS - you might want to look into the design and why this has happened multiple times (I had read that this was ... read more an issue for another person on the reviews as well). I would still highly recommend this product though.

      Hreat Stuff!
      We have been getting all of our pool products from In The Swim for several years. Everything does exactly what they are supposed to do. The Shock and this product are awesome. We have a 44k gal inground pool. Its a struggle to keep the levels up due to size and sun. This product gets the water back in shape over night!! Thank you In The Swim.

      The Better Chlorine Tablets
      The chlorine tablets bought from In the Swim are more consintraed, longer lasting tables. Than the ones iI tried from local supply stores

      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!

      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!

      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.

      Great product, free next-day delivery!!
      We have always used these sticks, slow dissolve, fit perfect in chlorinator, free next-day delivery.... what isn't to like the ease of this?!?!

      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.

      Works as Good as Chlorine Tablets
      Works Great. Been using Bromine Tabs for years instead of Chlorine Tabs. Cleans and sanitizes just as well as the Chlorine tabs, easier on the pool surface, easier on your eyes, lasts just as long.

      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??

    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.
