      Great Tablets!
      Been using these chlorine tablets for several pool seasons now. They do a great job. More economically priced than those sold through my local pool - chemicals stores. Fast delivery. In the Swim is very reputable!

      50# buckets and same as the big names is awesome.
      These protect our pool just as well as the big name guys and dissolve just as slowly. From what I can tell Chlorine percentage is the same/same. What I like is the fact I can get a 50# bucket instead of being limited to a 35# bucket. We love these so much we also started to purchased their bromine tabs for our hot tub at our home in Montana where I could finally purchase 25# of bromine at a time. In the Swim has become our go to source for pool and hot tub chemistry supplies. Price is ... read more always awesome. Delivery is quick and product is good quality.

      Worth the money
      First time ever owning a pool. A friend of mine referred me to in the swim. I chanced it by making the purchase but am so thankful. My water is crystal clear and this makes everything easy. These tabs make me thankful for owning the pool. I refer everyone to these tabs.

      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!

      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.

      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.

      Great value, even better when on sale!
      I have a 60,000 gal in-ground in the middle of the woods in the northeast... constant debris, wildlife, etc. making its way into the pool on a daily basis makes keeping the chemistry balanced and inhibiting algae growth a constant struggle. Previously I was running to the local pool store and picking up liquid chlorine 15 gals at a shot to balance and shock the pool in conjunction with my In The Swim Tri-Chlor tablets in my 2 chlorinators. I decided to give the Calcium Hypochlorite ... read more Sanitizing Granules a shot when I saw the 50# container on a great sale price while reordering my Tri-Chlor tabs. My first shock treatment only took 6# of granules, where as I typically would need 10-15 gallons to reach the same effect. Cost to product ratio was far better with the Granules, plus I can store the 50# much safer in a smaller space than the equivalent in liquids with fewer trips. Not to mention I'm far less likely to get a chemical burn from splashback or accidental spillage with the granules. From my initial experience, I estimate that I will continue this method over liquid chlorine from now on.

      Great results
      We had a strange winter and the weather here in Texas created havoc on our pool. I would recommend these sanitizing granules for year round pool maintenance. It even worked on a pool stain we've been trying to remove for a while now. Buying in bulk from In the Swim is recommended, it saves a good amount of money in the long run.

      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.

      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.

      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.

      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.

      50 lb tub 1"Chlorine tablets
      I have used these tablets for 20+ yrs and find them to be the best in delivering concentrated Chlorine in a minimum of pump running time. The resealable tub and individual packets in the 50lb tub are so convenient. 1/2 packet every week in my 40k gal pool in ground pool. I won't use anything else.

      Quick Delivery and Packaging
      First time user to In the Swim. I placed an order at noon on Monday, and the Chlorine tablets were delivered by 1:00 PM the next day. In the 10 pound container, the tablets were packaged into 1 pound segments. Definitely saved money vs. a pool store.
    3. 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.

      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!

      Takes the place of multiple chemicals
      Using Di-Zap and compounded 3 inch tablets for chlorinator is all you need to keep pool sparkling clean. Cuts down on need for purchasing a bunch of other chemicals.
    3. 3 years ago
      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.

    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.
