    Chlorine Free Chemicals

    1. 1 decade ago
      Phos Free
      I have used Phos Free for 4 years now. I would recommend this product, and have done so, for the ease of use, the great job it does cleaning up the spring algae and also for the great job of keeping the algae in checkall summer long. As it keeps the algae away, it also keeps those annoying "swimmy bugs" away. I hate those bugs, but have no problem with them as long as I use the Phos Free once a week. This has been the best thing for a pool since Chlorine!

      best product, best deal
      It is now a known fact that algae cannot survive without phosphates, and Phos-Free easily brings your pool's phosphate level to zero. Since using this, I have never had even a hint of algae (and it was a significant fight before then). Plus, the 3 liter bottle from In The Swim costs about the same as what my local store charges for a 2 liter bottle. I usually get 2 bottles (which meets the free shipping level) and I'm good for the season. Not only that but a free test kit is included so you know ... read more it's working. All around, my favorite item from In The Swim.

      Cheap chemicals
      Phosfree worked great, we've had a pool for over 33 years , Never had to worry about using phosfree until the last few years.chemical companies are making the chemicals cheaper with phosphates thus costing us consumers money.Also watch out for cyanuric acid if this is to high you will have to drain your pool to get rid of it.its on tablets and shock.

      Great alternative to chlorine
      This product really cuts down on the use of chlorine. I use a lot less now and our bathing suits last longer and no more burning eyes!!!

      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.

      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.

      Ionizer & replacement Chambers
      Have had an Ionizer since 2002!! Original main unit still working great!! Do replace the ion cartrrage about ever 2 years!! This ionizer is wonderful!! I do not have to use a lot of chemicals year round do to the ionizer!! Basically 1 bag of In The Swim Super Shock once a week in summer and when our tempt reach 90's and above we may have to add about 1/2 a jug of muratit acid through out the whole pool!! Crystal clear water !!! So do not hesitate to order , install the Ionizer and replacement ... read more chambers will save you a lot of $$'s in yearly chemicals!! Well worth the cost!!!

      Absolutely love my Copper Ionizer
      I bought mine 3 years ago. I have a 25ft above ground pool. It works like a champ. I run my pool all year round and I only have to add 1 lb. Of shock per week. Best choice I ever made. I recommend adding a quick release on both sides of the ionizer so you can easily change the chamber each year. Cost to replace the chamber is about $95. It saved me several hundred dollars every year and tons of maintenance time. The unit will fade if you leave it in direct sunlight over time but it will still ... read more work like a champ. I put a small cover over mine. No chlorine, no salt. Open your eyes under water with no problem. Best decision I ever made with my pool.

      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.

      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.

      Going on 15 years
      I was skeptical when my pool guy installed the nature2 years ago, but when I neglected to buy a new cartridge the next year I sure noticed it! The minerals really make it easier to manage the water and gives it a sparkly look. Definitely do not neglect to replace the cart since then, saves me at least as much as it costs, on less chlorine tablets. I only need less than 25 lbs tabs for the whole summer (27,500 gals, inground). Love my nature2 filter!

      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 Price
      An annual replacement of the mineral reservoir is a must for my system. The local pool company who built the pool charges 50% more than you guys. Thanks for not ripping off customers who have to have a proprietary item.

    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! :-)
