    Chlorine & Bromine

    1. 3 years ago
      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!

      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.

      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.

      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.

      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!

      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!!

      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.

      chlorine
      Works just like the very expensive chlorine other stores sell.
    1. 2 years ago
      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.

      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 product, excellent service ....
      I love 1" chlorine tablets and ordered a 50 lb bucket. It is hard for me to lift this weight so I had geared myself up to lift it and pour some tablets into a smaller container to put into my chlorinator. Imagine my happiness when I opened the 50 lb bucket and found it already divided into smaller cellophane bags. All I had to do was take out a bag, cut it open, and put into the chlorinator. I am keeping the algae at bay and not putting my back out. Thank you soooo much!!!!

      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.

      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.
    1. 10 years ago
      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.

      No More Trips To the Pool Store !
      Ever since I switched to In The Swim I no long make weekly trips to the pool store. The products are fantastc and get shipped direct. I love the Chlorine Sticks I have tried all the expensive brands and for the past two seasons I have used in the swim brand and my pool is crystal clear. I use three products from in the swim - Clorine Sticks . Phree and clear and pool perfect with phosfree THATS ALL !! and it been the best two seasons in 10 years. Check out the other products as well

      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.

      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.

      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.

      Cheaper then Liquid
      My second year with this product. Works great, quick delivery.

    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.
