      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.

      Easy. Once a week in the dispenser and I’m done
      Used these last year. Kept my pool almost 100% clean. My pool Gets full sum so only had a tad bit of algee in the hottest days. Other than that. I add 3 tabs a week and it’s crystal clear.

      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!!! .

      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??

      Individually packaged bags of tablets
      I got the 50 lb. bucket and all the bromine tabs were portioned into easy to pour bags. Much easier that trying to scoop the tabs!

      Works great
      Bought second time around, really has the best sanitizing power of any I've used before. Clear clean water. Only have to shock 1 time a month. Like the separate bags, no messing with reaching into the can and have the bromine smell for a day or two.

      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!

      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.

      Works well
      Great price for this product. Took a little longer to get than I thought it would but that may have been the carrier's falt.

      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.

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

      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!

      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.
    3. 4 years ago
      Disappointed
      Was hopeful it would dissolve much better than it did. Having to brush the bottom of the pool with each application is not worth it. The chemical part was fine, just didn't enjoy the brushing. I will go back to liquid chlorine.

      Individually wrapped 3 inch chlorine tablets
      Individually wrapped 3 inch chlorine tablets I have bought these the last six or seven times I bought Tablets. I like the rate they dissolve play seem to be consistent in unbroken.

      Love ITS!
      The 3-inch chlorine tabs are a staple for a pool owner, but the ones from ITS are high quality, individually wrapped so you don’t get chemical all over your fingers, and cheaper than I can get them from any pool supply store in town (including Leslie’s). Love the 2-day delivery to AZ too!

      Easy and convenient shopping
      I just purchased 50 lbs of the 3” chlorine tablets and they arrived at my doorstep within a day. I order all my pool products from these folks and have never been disappointed in the quality or service.

    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.
