    Chlorine & Bromine

    1. 12 months ago
      Not anti-scale
      I've been using these for about a year now in my well chlorinator, and I have to descale it weekly.

      Works like a charm
      So much more stable for our pool than regular chlorine tablets. A step in the right direction!

      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.

      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.

      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.

      Dissolves instantly
      I use this in my spa and love it because there is no mixing. Just measure and pour in with jets running running. Dissolves instantly

      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.

      Chlorine
      Always easy online ordering and even faster delivery

      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.

      They do dissolve very slowly
      if you want slow you get slow. I also use granular chlorine but have some of these in a floater to keep up in the heat. I put some in more than 2 weeks ago and they are still not completely dissolved..maybe a bit too slow for me but it is what they are advertised to do.

      Good stuff great prices
      One cup a day for my 24x4’pool is all I need. Keeps water clear.

      Excellent product
      Great product for quick clorine adjustments. I use it in combination of float with 3 in tablets.

      Great Product
      I love the fact that this product works so well with no fuss and muss, You dump the appropriate amount into the skimmer basket and let your filter do the rest. I have no problem maintaining the proper chlorine level and the filter does all the work. If you do run into any algae growth, a heavier dose of this product works well to kill it. No wasting money on costly algaecides. Reccomended doses for weekly shock are on the container too. I also love the safety lid. I have used many that are just ... read more so hard to open, this one just has you squeeze the tab and rotate. No more fighting the lid just to get to the chemical.

      great product
      Have been using this product for two seasons and really like how easy it is to keep the pool water clear. In fact, I only used one package of shock at the start of the season and then started the calcium hypochlorite regimen. The water was clear in not time at all.

      Great product
      My CYA was getting high so I needed something to add chlorine/shock my pool that wouldn’t increase it. This is exactly what I needed! It works well and my pool is very clear.

      Great Results
      Great product. First time in years my pool stayed crystal clear all summer long. Direct result of the Super Multi Tabs.
    3. 2 years ago
      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.

      What can I say? They're round, they're white, they smell like chlorine. They're the best darn chlorine tablets ever.

      Great Product
      On the advice of a fellow pool owner I tried using liquid bleach from my local supermarket to chlorinate my pool. He assured me I would see a significant cost saving. I regret that he was talking rubbish! Mid swimming season I realised the sun burnt off the bleach at an alarming rate plus the ph was bouncing around requiring more chemical input to cure. So back I went to In The Swim Chlorine Tablets. My 35,000 gal pools uses 4 tablets a week, ph is stable and the water sparkles.

    In The Swim Knowledge Pool: Chlorine & Bromine

    In The Swim's Dr. Pool

    Differences between Chlorine and 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, they have distinct differences, and unique properties to offer benefits to certain users. Bromine vs. Chlorine? Read on for more information about pool and spa sanitizers. 


    Chlorine and Bromine

    • - Bromine can be reactivated to reduce cost, but bromine tabs cost more than chlorine.
    • - Bromine is more stable in hot water, longer lasting sanitation, even during full use.
    • - Bromine is more stable in wider pH range, remains strong under high pH swings.
    • - Bromine Less odor to the water, and less irritation to skin and hair.

     

    • - Chlorine tablets are the most economical way to sanitize a pool.
    • - Chlorine tablets are stabilized for sun protection, slow dissolve formula.
    • - Chlorine tablets dissolve rapidly enough to treat larger pools effectively.
    • - Chlorine dissolves faster for quick superchlorination or shock treatment.

    There are Several Chlorine Options:

    Chlorine dissolves fast and almost instantly begins to sanitize your pool water.  Chlorine tablets or chlorine sticks can be used in floating chlorinators, or placed to dissolve in an In-line or Off-line chlorine feeder. You can also make use of granular chlorine, dissolved into a large bucket of water for vinyl pools, or sprinkled directly into most concrete pools. Liquid chlorine is another option that offers affordable versatility for sanitizing your swimming pool.

    Chloramines form when a chlorine molecule has combined with ammonia or nitrogen and produces the familiar chlorine scent often associated with swimming pools—it’s not the smell of free chlorine, but of combined chlorine. As chloramines build up they reduce the effectiveness of chlorine—like a traffic jam. When Total Chlorine (Free+Combined) is greater than 0.3 ppm, (TC-CC=FC), this is time to shock your swimming pool. 

    UV rays from the sun breakdown chlorine molecules which also contributes to making chlorine less effective. Although our chlorine tablets are stabilized, it takes some time for a residual to build up. Pool stabilizer (aka conditioner) contains cyanuric acid, which combines with chlorine, protecting the chlorine from sunlight degradation. It’s like sunscreen for your chlorine, and will save you money spent on chlorine in the long run. 


    Can I use Bromine In My Pool?

    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 is a popular sanitizer for indoor pools or heavily shaded outdoor pools. Indoor pool owners enjoy the softer odor of bromine, and enjoy the ability to re-activate bromides into bromine, simply by shocking the pool (with chlorine!). 

    To use bromine tabs in a spa, you will need to have a bromide ion 'bank' built up, or a preexisting level of bromide ions (the reduced form of bromine). Many spa users add Brom Booster to raise levels quickly after draining the hot tub. Then you can simply use the bromine tabs in a feeder or floater. Bromine is far more stable and effective in high temperatures, which is why it is almost always used in spas and hot tubs.


    Can I Use Chlorine In My Spa?

    The money you will save by purchasing chlorine over bromine for use in a spa is negated rather quickly due to the fact that you will need to use much more chlorine to keep the spa sanitized due to the heat of the water, heavy bather loads, and since it cannot be reactivated the way that Bromine can. Bromine tablets can be used in small floating feeders in spas or hot tubs because they hold such a small amount of water and the bromine can disperse more effectively.

    Bromine is also more effective over a broader spectrum on the pH scale than chlorine. In the context of a spa, 4 people entering the water can cause extreme swings in the spa pH level since it is a significantly smaller volume of water. When pH levels rise above 8.0, chlorine can become 50% less effective, whereas bromine remains potent at higher pH levels.


    Never Mix Chlorine and Bromine

    Some people may choose to sanitize via bromine because they have sensitive skin.  Some people prefer the convenience of chlorine’s ability to quickly be raised or lowered. However, if you do decide to switch from one to the other you will need to buy a new feeder or floater. Mixing Chlorine and Bromine can cause a dangerous chemical reaction with even the slightest bit of residue.
