      Super Service, Super product
      I ordered 50lbs of granular chlorine one morning and it was delivered to my doorstep the next afternoon. Not only is the service great, its the best product I have ever used and we have been using granular chlorine since 1963. This product is stabilized and leaves no residue. All this means no algae and no problems. I have to laugh at friends who struggle with green scum for weeks. Mine clears up in 1 day. LOL.

      Purchase of chlorine tablets
      I have bought your tablets bc are cheaper here than anywhere else. I like that they are individually wrapped. Will continue to by from you for my chlorine needs.

      Easy install
      Very thin for the price. I just put the cover on, so I can't really comment as to how it's going to hold up. It was very easy to install. Comes with a cable and a ratchet to attach the cover to your pool. I have an above ground 15' easy setup pool. I ordered the 18' cover because when I winterize my pool the water level is lower than 6 inches so it was recommended to order up a size and it worked perfectly. I also ordered the clips to go along with it, but I didn't end up needing those. Much ... read more simpler to install than the cover that came with the pool.

      Great Product
      Good value, this quantity works perfect for me. We keep our pool up year round, so these tablets are the only brand we use. Shipping is so convenient, never have to run around looking for chlorine tablets.

      So far, so good
      Had too much CYA from “stabilized chlorine” and needed to lower, this product gave me chlorine without CYA, and I’ve had seen my CYA lowering since using it (have had to pump pool few times due to rain) but I use about 6-8oz every other day for 20k gallons, and have had no issues. Was worried about price paid and thought of it not lasting long, however, I’ve hardly put a dent in the bucket, and probably could make a full season last from one bucket at the rate I’m using currently

      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.

      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 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.

      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!

      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.

      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.

      Great Product for a Great Price!
      I especially like these chlorine tablets because they come in individual bags. Each portion is measured to fit perfectly in the float that goes around the pool. So if you have a pair of scissors, your skin never touches the chemical. Very little dust. I am so thrilled with the ordering process. It gets delivered to my home within 1 to 2 days!! And no hauling from a store!

      Works as Good as Chlorine Tablets
      Works Great. Been using Bromine Tabs for years instead of Chlorine Tabs. Cleans and sanitizes just as well as the Chlorine tabs, easier on the pool surface, easier on your eyes, lasts just as long.

      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.

      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!

      I used this product last summer and had the least pool maintenance in 30 years. My pool water remained clean and shiny throughout the summer.

      Replenished our supply
      In the Swim ships quick. Very competitive prices. This tablets work great at maintaining our chlorine level. We put a tablet in each of the skimmers and the water remains crystal clear. The tablets last about 3 to 4 days (less on real hot summer days). We repurchase these tablets at least every year.

      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.

      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.

      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.

      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!

    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.
