      So easy to maintain pool now!
      I discovered these multi tabs this year and have used them from the time of start up. My pool has never looked so good or been so easy to maintain. I take pool water to be tested once a month and have only had to adjust the alkalinity one time(after a heavy rain). Other then that I have only used these tabs and all pool chemistry has been perfect! Fun to own a pool again.

      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.

      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!!

      CRYSTAL CLEAR SPARKLY pool, better than Calpo!
      We switched from super-shock to Dichlor for our 18x33' above ground pool because our well water is extremely hard, and this brand of it is awesome! 99% sodium Dichlor clears our pool SO FAST! Calpo took WEEKS to clear a green pool. With di-zap, we have a crystal clear pool in ONE day. Beautiful, clear, SPARKLING. Amazing. Plus it helps keep our stabilizer levels up... another problem we were having. And it dissolves quickly & completely - no liner bleaching. Love di-zap from In The Swim!

      Bought to help in the management of our salt system pool after having the same recommended by the pool supply where a water sample was taken which is about 29 miles one way.

      CL2 in BIG bucket
      Great big bucket of CL2, and it comes with a blue scoop w measuring markings with is perfect to assist with getting the amount you need. Just know the percentage of CL2 in the ingredients listing so you know the strength of the CL2 you purchased. I was aware of the strength at purchase.

      In the Swim 3" Chlorine Tabs
      The 3" chlorine tabs work just fine. Free shipping and fast delivery a decided plus. Each tablet is in a sealed plastic bag which I like, but now I know why. The tablets are fairly soft. They break easily and don't last as long as say Regal chlorine, whose tabs are like rocks. Overall good deal though - good price, free and fast shipping, and friendly service.

      3" wrapped pucks
      I enjoy not getting hit in the face with the chlorine when I open the bucket. The wrapped pucks are a pleasure. With these tablets I find that I have to shock the pool a quarter less than prior to using them. Highly Recommend these.

      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.

      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

      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!

      4" sticks work well in floating chlorine distributor, much better than 1" pills.

    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.
