    Chlorine & Bromine

    1. 2 years ago
      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!

      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.

      Multi-Tablets are very effective
      Tablets are very effective and provide for essential carefree pool maintenance. Pool is crystal clear, free from algae and inviting for swimming. Would recommend them to a friend.

      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.

      excellent pool shock & spa super chlorinator
      I have had a pool for 35 years and have always used dichlor as my shock (except for hth early on). it works great and the price is good (wish it were cheaper but In The Swim's price compares favorably to the competition). the tub lid is easy on / easy off. NOTE: If you buy a tub for the pool and have a spa, set some of this product aside for use as your spa chlorinating agent. (It is a lot cheaper than buying the spa chlorinating agent which is the identical formulation).

      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.

      Caution!
      When using "Stabilized" Chlorine 3" tabs remember that you're adding cyanuric acid (54% by wt.). If you load up with too many tabs and increase the water flow to the chlorinator you may get too much acid which inhibits the effectiveness of the chlorine.

      The best on the market
      Love these chlorine tablets. I have used them for years. They keep my pool crystal clear with less than other products.

      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 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.

      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!

      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.

      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!

      Best shock thay I have ever used.
      I got a box of 12 bags & I'm glad I did. It does more than shock. I have a fibreglass pool and had trouble with staining when I shocked with a different brand, it also dissolves quickly

      Great chemicals
      I love these. I buy the 50 pound bucket & the tablets are wrapped in smaller bags within the bucket. It makes handling & storage much easier. We use these to refill our automatic chlorinator. I haven't had any problems since we starting filling it ourselves with these 1 inch tablets. We use to get alge from waiting for the chlorine cartridges to empty. Now I can just add more & not worry.

      Great Deal
      Have been a customer for a lkng time & this chlorine works great. It fits our chlorine basket perfect at a reasonable price & free delivery. Also love the coupon codes that make it an even better deal.

      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.

      The perfect chlorine
      I have been using this chlorine for my pool for the past 2 years. It has done a great job. Wouldn’t want to use any other product.

      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.

      clear blue water
      It instantly clears green algae water to blue, crystal clear waters.

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


    Chlorine and Bromine

    • - Bromine can be reactivated to reduce cost, but bromine tablets cost more than chlorine tablets.
    • - 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 tablets are stabilized 1" or 3" slow dissolve Trichlor tablets and 8 oz. sticks.
    • - Chlorine tablets dissolve rapidly enough to treat larger pools effectively.
    • - Chlorine granules react instantly for rapid super-chlorination or shock treatments.

    Swimming Pool Chlorine Options

    In The Swim tablet chlorine dissolves fast and almost instantly begins to sanitize your pool water. In The Swim 3 Inch Chlorine Tablets are 8 oz. stabilized Trichlor tablets, and are also available as a 0.5 oz. pellet, in our 1 Inch Chlorine Tablets. In The Swim 8 oz. Slow Dissolving Pool Chlorine Sticks work fast and last longer. Our 3-inch Super Multi-Tabs are unique pool chlorine tabs with stabilizer, algaecide and clarifier added. Sticks or tablets can be used in chlorine floaters, or place the pucks in an in-line or off-line chlorine feeder, to provide a daily chlorine level that is consistent and constant. 

    In The Swim granular chlorine like the economical Cal-Hypo granular chlorine and stabilized Dichlor 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 chlorine powder directly into concrete pools, spas and fountains to maintain free chlorine levels, to raise chlorine levels rapidly, or to super-chlorinate the pool. Granular chlorine is used regularly to quickly kill algae and bacteria, and 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 chlorine 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 chlorine. When 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 combined chlorine molecules. 

    UV rays from the sun breakdown chlorine molecules which also contributes to making chlorine less effective. Although our pool 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 to protect your pool chlorine from sunlight degradation. It’s like sunscreen for your chlorine, and will save you money spent on chlorine 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 20-50 ppm range, keeping a close eye on pH will reduce your chlorine expense, 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. 

    Can I use Bromine In My Pool?

    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 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. In The Swim 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 because bromine cannot be reactivated. 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 tabs are also more effective over a broader spectrum on the pH scale than chlorine tabs. 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. If you do plan to use chlorine in a hot tub, please use spa chlorine products, not pool chlorine.

    Never Mix Chlorine and Bromine

    Some people may choose a bromine pool because they have sensitive skin, or for indoor pools. Other pool owners prefer the convenience of pool chlorine and the ability to quickly raise or lower levels. However, if you do decide to switch to pool bromine, you will need to replace the chlorinator with a Brominator. Mixing pool chlorine and spa bromine can cause a dangerous chemical reaction with even the slightest bit of residue. The same is true for all types of pool chlorine - Trichlor tablets and sticks, Cal Hypo shock and Dichlor shock - all will react violently with each other if mixed together, or with any other chemical.
