    Chlorine & Bromine

    1. 4 years ago
      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.

      No more chlorine for me
      I use Bromine in my above ground swimming pool. It works great and i dont have any problems with algae. I put it in a floating feeder and it slowly dissolves. Lasts a long time. It is not harsh to your skin and eyes. My nephew breaks out from chlorine when i switch to bromine he hasnt broke out since. Its a little expensive for how much you get but worth the performance of the product. Dont breath in the dust from it will get you. A lot of pool stores look at you crazy when you tell them you use ... read more in your pool. They dont know much about it. Its great.

      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.

      Super tabs
      Since I found these tabs my pool almost takes care of itself, the best pool tab I've ever used

      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.

      Did what they said they will
      I have not found a product that works as well for the same price. Each stick is individually wrapped so when you open up the bucket you are not COMPLETELY knocked over by the fumes. I also live in a moist climate so they do not deteriorate. I use the sticks in an in-line chlorinator and once you have your chlorine levels set, it's easy to keep the desired levels. In the Swim ships quickly and my order has always been correct. Their prices are much more competive than I can get from my local stores.

      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.

      My pool is too small to use the skimmer sticks
      Last year I purchased skimmer sticks from my pool man and thought they were working wonderfully. This year pool man never returned my calls so I purchased from you. I found out that my stabilizer was off the charts due to the pool being too small for the skimmer sticks. I think they are great for a large pool. I have used products from In the Swim in the past when I had much larger pools. Too bad. Now I need to see if I can sell my 10 lb bucket minus 1 stick.....

      Great Value
      This is my second time purchasing the 50 lb bucket from IntheSwim. It is the best price per volume that I can find at this strength. As a note, I did read a review stating that the lid would not budge, and I had the same issue with this (my second) bucket. I used a hammer to hit the lid counter-clockwise, and it came right off. It seems that they've hired a new, beefed up employee on the assembly line!

      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 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.

      I LOVE THIS LITTLE BOTTLE
      AT FIRST I WAS SKEPTICAL ABOUT THIS POWDERED INSTANT LIQUID -- I NORMALLY BUY THE LIQUID CHLORINE TO ADD TO MY POOL, SO AT FIRST WHEN I OPEN THIS BOTTLE AND SAW IT WAS GRANULAR I THOUGHT WHY WOULD THEY CALL THIS "INSTANT LIQUID CHLORINE" BUT I HAD NO CHOICE AT THE MOMENT AND USED IT AFTER A LARGE POOL PARTY AND BOY WAS I PLEASANTLY SURPRISED...IT MADE MY POOL CRYSTAL CLEAR AND I'VE HAD TO USE SO LITTLE TO MAINTAIN ON A WEEKLY BASIS...SO I LOVE THAT I'M ACTUALLY SAVING MONEY. THANKS IN THE SWIM!

      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.

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

      Great Value
      This is the first time I've purchased these from IntheSiwm. They have the best price per volume that I was able to find. I was disappointed to see that the tablets are individually wrapped. I looked back at the description, and I see that it does state that they are. I'd prefer that they were not individually wrapped, as this amounts to trash blowing away while I'm filling my chlorinators. The individual wrappers do not prevent your hands from wreaking of chlorine either, as I'd guess is ... read more their intended purpose.

      Excellent quality and incredible value
      The easiest thing about pool maintenance is “in the swim”. I am always impressed with the quality of the products and the excellent prices! These chlorine tablets are perfect. Inhuman pay more for chlorine tablets elsewhere? These are excellent quality!

      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.

      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.

      I was amazed
      This product amazed me - we had been using a lesser product and we had to mix it in water, pour it in through the filter and it STILL came out the spouts and settled on the floor of the pool. This product is simple to use - just sprinkle it around the deep end and watch as it quickly disolves prior to hitting the bottom of the pool - it immediately raises the chlorine level!

      Excellent product
      Great product for quick clorine adjustments. I use it in combination of float with 3 in tablets.

      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 Shock for Price and Excellent Pool Water
      Best Shock I've ever used in 25 years. Very efficient results with less use than in the past with lithium shock

      Works great
      Have been using for 3 weeks. No trouble keeping the pool sparkling and water clear.

    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.
