      Rated 5 out of 5 by from Great Product I love the fact that this product works so well with no fuss and muss, You dump the appropriate amount into the skimmer basket and let your filter do the rest. I have no problem maintaining the proper chlorine level and the filter does all the work. If you do run into any algae growth, a heavier dose of this product works well to kill it. No wasting money on costly algaecides. Reccomended doses for weekly shock are on the container too. I also love the safety lid. I have used many that are just so hard to open, this one just has you squeeze the tab and rotate. No more fighting the lid just to get to the chemical.

      Rated 5 out of 5 by from 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 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.

      Rated 4 out of 5 by from Chlorine is good! Ordering was a mess! As I said I have no problems with the product. I ordered it online then received an e-mail that said something went wrong incomplete order. Or something like that so I called and they placed my order for me. The next day I was billed for both orders. So instead of helping me like I asked with the order I did online they did a whole new order and both ended up going through the bank. To me it would be a total hassle to send one back so I have both which will eventually be used. If I could actually afford to pay double in the first place I would have gotten the larger amount and been done with it.

      What is the chemical make up of the granular chlorine?
      – 56% available stabilized chlorine, fast dissolving, 99.5% Sodium Dichloro-S-Triazinetrine.

      How much granular chlorine do I use?
      – Use 4 ounces per 10,000 gallons of water per day to achieve initial readings.
      – Use 2-3 ounces daily per 10,000 gallons to maintain proper chlorine levels.
      – Use 2 Lbs per 10,000 gallons for heavy algae until algae clears.
      – Use 1 Lb per 10,000 gallons for light algae until algae clears.

      How do I dispense my granular chlorine?
      – In The Swim recommends to have a bucket of water and add the granular chlorine to the bucket, and then broadcast around the perimeter while pump and filter is on.


      – If chlorine seems to be ineffective check the stabilizer also known as cyanuric acid. The correct level for stabilizer is 30-60 ppm. If the stabilizer is too low the chlorine will be used up faster making it appear that the chlorine is not effective. If the stabilizer level is too high it will slow down the oxidizing process and render the chlorine less effective. This must be compensated for by using a higher concentration of chlorine in the pool water.

      – If you believe the chlorine is defective/ineffective, you can test it by placing a small amount into a glass of tap water. (Do not use pool water.) Dissolve and test as usual.
