    Chlorine Free Chemicals

    1. 3 months ago
      Love Aqua Silk
      I have been using this chlorine free product for the last two years and I love it. No harsh smells, easy on my kids skin, when used properly water is crystal clear and lasts longer than the recommended weekly dosage. Highly recommend, just wish they still sold the system bundle pack!

      Best Purchase Ever
      I can now open my pool earlier for my Grandchildren as there is no work involved in maintaining the pool and large chemical bills. The liner and pool equipment do not lose their new feeling from chemical corrison. The liner feels new and no more smell of chemicals in my pool shed. I am purchasing one for my son's pool as a house warming gift and my next door neighbour is now purchasing the unit after see my summers results. I would recommend this unit to anyone.

      not a chore anymore
      I have been using the ionizer for about 3-4 years & it is the best thing. All I have do is clean & shock once a week unless it rains then I add extra shock it. We have never had a problem with our clothes fading or hair turning green. It's not a chore anymore to have a clean pool.

      Love it!
      This is my fourth above ground pool! It is my first ionizer pool system, we have had it four years! I highly recommend it, its been the best and easiest keep pool I have had! I wouldn't have anything else! We had to replace our ionizer system due to not having it covered for protection from the sun! But didnt have a problem with doing that!

      Really makes my pool sparkle
      Installed this on my 23,500 gal pool earlier this summer. You have to shock the pool afterwards (with chlorine), but after that I cautiously let the chlorine level drop below 1 ppm, and went from using 4 tablets weekly to 2 tabs per week. Water has never looked better, even with half the chlorine! I still shock the pool 2x per month, just to be sure the pool is sanitary, but I give Nature2 Express a thumbs up, if you want to cut down on chlorine.

      healthy family
      I love the mineral purifier! It allows me to keep the chlorine level at .5, and I only have to raise it and/or add algaecide during the hottest month! Thank you for a product that allows me to keep my family healthier!

      Great Product
      My pool was so green it was like pea soup. I purchased over $200.00 dollars of chemicals to clean my pool and it was still green. So I found the Nature 2 Express Mineral Purifier and purchased it 2 days after I installed it my water is clear all the green is gone. Also it's so easy to install it took about 15mins. Super great product very pool owner needs one.

      No More Algae Worries. Period.
      This is the second year that I have used Phos Free in my pool. I have to say it is the most amazing, time and money saving product that I have used in my pool. I have had no problem with algae, the pool is cleaner, I use far less chemicals, the water simply sparkles and is as clear as a bell. My usual two to three week pool opening this year was reduced to 5 days (using a lot less chemicals and $) thanks to closing last year and opening with Phos Free this year. It is worth adding to your weekly ... read more routine. In the long run this product more than pays for itself by using fewer chemicals season long. I am a believer and have the $ to show for it! Good luck. On a side note - the water is so clear after using this product that I can see the smallest spec in the deep end - it is like crystal!

      WOW - Best Purchase Ever
      I bought this product hoping to better manage my potential algae problem during the summer when on vacation. Sometimes my husband forgets to check the chemicals if I'm out of town and I would get to come back to an almost green pool. Now it's simple, a few capfuls in the skimmer before leaving and I come back to a worry free pool. I haven't had ANY algae problems even with the solar discs on and leaves in the pool! Simply amazing!!!

      An absolute must!
      I've used Phosfree for years from Spring start up to Fall close up to help keep an algae free pool.

      Love how it works now that I have the correct one!
      I bought this and the mineral cartridge didn’t fit! I had to reorder a different one! Make sure you have the right one for your frog!

      Great product
      Buy this product every year from In the Swim - best price and packaging!! Works great to keep the pool chlorinated at just the right level without having to check it daily.

      Five Stars for the Pool Frog Inground
      I have been very pleased with the Pool Frog Inground Mineral Purifiers. I have had the Pool Frog in use since my pool was installed and will continue to use in the future.

      Great fit!
      It's a great fit and value compared to price of new filter. Easily installed and works great.

      Excellent Product
      I started with an EC75 "finger style" DE filter. I had a few problems and wound up upgrading to this unit. It seems to be much better made and is much easier to maintain for a few reasons. First, if you add the multiport valve, backwashing, rinsing, draining excess water, etc. can be done with the turn of a wrist. Secondly, the every-few-year maintenance you're supposed to do with a DE filter (i.e. opening it up and hosing all of the membranes off) can be done by removing a single bolt, and none ... read more of the plumbing has to be undone. The EC75 requires the disconnection of the plumbing and the removal of something like 20 bolts. Overall, I'm very happy with this filter, and it's definitely worth the extra money considering that this should be a 10 year investment.

      Great Upgrade
      I replaced a old DE filter with the new Hayward Pro-Grid. I love the new Perma Glass shell as opposed to my old stainless model. Much improved clamping system, and the new control valve makes backwashing a breeze.

      very little chlorine
      Been using for the past 4 years. Very little chlorine needs to be used. Pool liner still looks new, no color fading. Just need shock in the opening to energize the minerals--works great. need one every year

      Works great!
      I have been using the A2538 cartridge for years. I replace it when I open the pool in the spring. It works great! We use much less chlorine and the pool stays nice and clean.

      This stuff is great!
      I love Nature2! Nature2 is a Silver Nitrate water treatment system that takes the place of Chlorine. Which means no balancing or adding chlorine on a daily basis. The Nature2 dispenser connects to your pump and dispenses Nature2 automatically. Making the pool chlorine free. Maintenace is a breeze. Just vaccuum, add shock, and a small amount of Algecide and Clarifier weekly and you're good to go!! It's great!! The only drawback is that you have to pay $120 for the cartridge all at once. But it's ... read more completely worth it! Cartridges last six months.

    In The Swim Knowledge Pool: Chlorine Free Chemicals

    In The Swim's Dr. Pool

    More About Chlorine-Free Pool Chemicals

    More pool owners are making the switch to chlorine-free pool chemicals. The smell and taste of chlorine can be off-putting to many swimmers and some people even have allergic reactions to chlorine. Some pool owners therefore prefer chlorine free pool chemicals to eliminate completely or greatly reduce the amount of chlorine in their pool water. Alternative chlorine-free pool chemicals use natural processes and nature's own chemistry to sanitize pool water. 


    Reducing Chlorine Demand

    The most effective way to reduce chlorine use is to add supplemental sanitizers. Ozone, UV Systems and Mineral Purifiers all allow you to use 1/2 as much chlorine, while enjoying an improvement in water clarity. Enzymes reduce organic load in the water and clean your filter, naturally. Clarifiers and Algaecides also can help you reduce the amount of chlorine needed on a daily basis, and further reduces the need for shocking. In most cases however, you will still need an oxidizer, occasional pool shock treatments, although chlorine-free pool shock can be used just as effectively in most cases. 

    Going Completely Chlorine Free

    You can go completely chlorine free by doubling up on supplemental sanitizers. One such method is to use either a Ozone generator or UV system combined with a Mineral Purifier, like Nature2 or Pool Frog - and together they can manage almost all of your pool's sanitation needs. Of crucial importance to such a chlorine-free pool is proper water balance, a very effective pool filter, a clean pool, and weekly shocking with non-chlorine shock. Additional support can be found with natural Algaecides, Enzymes or Clarifiers if needed.   

    Aqua Silk Chlorine Free Pool Treatment

    Aqua Silk is a simple 3-step pool sanitation system that is completely chlorine free, relying on powerful disinfectants used in hospitals and other places where sanitation is critical. In The Swim carries Aqua Silk, a proprietary blend of biguanide sanitizer, peroxide oxidizer and algaecide, sold in a convenient kit. You will still need to maintain balanced pool water, keep a clean pool, and run the filter long enough each day to maintain water clarity. But, you can say goodbye to chlorine forever! In fact, if you do accidentally use chlorine in an Aqua Silk pool, it may turn a sickly orange color! :-)
