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

      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.

      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.

      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.

      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!!!

      Saves on chlorine
      Ever since using the Nature2 purifier in our pool, the water has been crystal clear and easy to manage! Highly recommended, even though it's a bit costly.

      Nature 2 is the best
      The most important purchase I make each year is a nature 2 replacement cartridge, it keeps my pool crystal clear all summer long.

      Great product
      I bought these at the beginning of the pool season. It works just as described and was delivered in a timely manner. I will buy them next season.

      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.

      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!

      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.

      Works Great!
      I started using this product last year. It is very easy to use and the best thing is it is not chlorine. However, if you purchase this be VERY AWARE that you MUST BE HOME to sign for the Oxidizer!. In the Swim should really specify this when you order this. It is a federal law because apparently one can use this product to create explosives. Please, In The Swim, put a red asterisk or something to that effect, indicating that you must physically be present to sign for this product, and educate ... read more your employees that this is the case as well. Three (3) different employees assured me that I didn't, and sure enough! I did! This caused a major delay in re-directing the shipment to me.

      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!

      Excellent product
      Use this product in our above ground pool. Love it ... better than any chlorine product. Would highly recommend. Quick delivery as well.

      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.

      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!!!

    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! :-)
