      Works well
      Very good product to use with Solar Sun Rings. In these drought conditions I'm saving many gallons of water. Evaporation is about 75% less than without these products. Also $10.00 less per unit than the swim centers.

      Excellent service
      This is a great product. Pool temperature started increasing shortly after use. The containers leaked slightly during delivery. In the Swim replaced both containers without question and I received them the next day!! Awesome!

      Eliminated my phosphate problem
      I have a 20k gallon inground fiberglass pool. The last two years I've had had to deal with cloudy water due to excessive amounts of phosphorus from lawn fertilizer and airborne insecticides. I started adding two capfuls of Pool Perfect w/Phos Free into my skimmer about every two weeks. My water has never been cleaner. The phosphorus would settle in at the bootom of the pool (looks like sand) and I could easily vacuum it out to waste. I would recommend all the Natural Chemistry products.

      Great Product!
      Until we began using this product, we had recurrent problems with algae, no matter what algacide we used, or how we cleaned the filtration system. Once the problem of phosphates being present in the water was addressed, through the use of Phos Free and then Pool Perfect with Phos Free, we have had essentially no problems with algae for over three years. Before then, we battled yellow algae throughout the season, as well as having problems when the pool was first opened. Just remember to always ... read more soak your DE fingers every 4 weeks in muriatic acid regardless of how little your pool is used.

      Once a Week Wonder!
      If you want the BEST looking pool possible and also want to reduce the time you spend to make it that way, this is the product you need! I'm not kidding! I live in the midwest so our pool is only open from Memorial Day to October. The last two seasons after the initial pool cleaning/vacuuming, I've used PH Perfect & PhosFree and it has eliminated the necessity of virtually all other chemicals, except chlorine tabs and an occasional dose of PH increaser after a heavy rain. Before I switched to PH ... read more Perfect & PhosFree, I always had some degree of algae form, but NOT ANY MORE! All I do is add 4 capfuls into the filter every weekend. That's it! You will not be disappointed!

      PhosFree Believer
      9 year user. Got first sample from my pool builder. I hate the dangerous chemicals in algaecides, and don't like the foamy water, algaecide taste or water ring from dead algae. Open pool with shock & algaecide. Vaccuum and clean the waste. Balance pH, test phosphate. Use phosfree if elevated, then weekly phosfree + pool perfect. Keeps water sparkling with no foam, no water ring and no algae, even through August. Will occaisonally add a dose for unusually hot weather or a lot of rain. (I don't ... read more find the spring / fall treatment to be useful. Even with use at recommended dose, still need algaecide to open.)

      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!!!

      Ring around pool gone in salt pool, no more algae
      Very large deep salt pool always had problem with a couple walls accumulating yellowish clouds or a film of algae that even pool services could not rid. Also accumulated very ugly white thick ring of calcium? Even acid would not remove without etching beautiful tile. Ring and problems GONE IN MY SPARKING CLEAR POOL, ONE CAP FULL A WEEK, 1 1/2 3 liter bottleS of PHOSFREE later, I STARTED WITH ONE CAP FULL AND NEVER INCREASED THE QUANTITY.

      Excellent product
      I have used Pool Magic for several years now and it has proven to be an extremely effective treatment to jump start my pool opening. I also use it to close up the pool in the fall. Well worth using.
    2. 1 decade ago
      Never will use anything else!
      This product is the best! We fill our pool with well water and it clears it immediately as well as keeps it clean all season. We add it in the Fall and Spring clean up is a snap.

      best product i ever used in my spa.i've had hot tubs for over 12 years and this works the best ever....
    1. 1 year ago
      Seems to work
      Due to lots of rain and water temperatures around 95, we were getting heavy algae requiring frequent cleaning and diatomaceous filter changes. After through cleaning and shocking I used the recommended amount of algaecide and after 10 days no algae or filter changes. HOWEVER, the water is no longer crystal clear; it has a yellowish tint.

      Iron in our water
      Bought the Stain Away and the Metal Free, used it according to the directions and my water is like it should be except for cloudiness. Another reviewer suggests putting in clarifier which I am about to do. Our Kempner Water Supply co-op has lots of iron in the water that they distribute to us, (water looks like brownish urine when new pool water is filled) and when you shock/chlorinate the pool, it immediately turns like brown nasty water, because chlorine oxidizes the iron content. These two ... read more products are a Godsend to all pool owners! I will continue to buy this and continue to dose my pool when topping it off as it suggests to do. No more brown water!!! Yeahhhhhhhhh

      Metal Free
      I have been bouncing back and forth with a phosphate problem in my fiberglass pool. Turns out, the pool store was selling me a product with prosphates in it for the stain removal. Therefore, the phosphate level kept rising. Months later, I discovered what was happening and immediately looked for a stain remover with no phosphates. I found Metal Free on the In the Swim website. I bought it, put it in the pool following the directions on the bottle and had my water tested. IT WORKED!! Metal Free ... read more cleared up the stain and no phospates in the pool........

      Did the trick
      This product removed the brown staining on my fiberglass pool steps and other white trim in my pool. Our well water has high concentrations of magnesium and iron, so we are always battling the stains. This saved me having to purchase another stain removing product

    In The Swim Knowledge Pool: Natural Chemistry

    In The Swim's Dr. Pool

    Eco Friendly Pools and Natural Chemistry

    From pool openings to pool closings and every wonderful summer day in between, Natural Chemistry products work effectively with chlorine-based chemicals by employing natural occurring enzymes that eliminate oils and organics in your pool water. In The Swim has all of the Natural Chemistry pool clarifiers, pool enzymes, pool stain removers and preventers, phosphate removers, instant pool conditioners, and liquid solar cover - the entire product line!


    Natural Chemistry Enzymes

    Natural Chemistry enzymes have been perfected over 25 years, and today's Smart-Zymesâ„¢ are better than ever. Enzymes are the natural and safe way to break down oils and non-living organics in the pool while preventing stains from metals and organic debris. Enzymes also clean your pool filter, naturally. Natural Chemistry Pool Perfect is the original pool enzyme formula, quickly joined by enzyme/clarifier blends like Pool First Aid, or Pool Magic, and Pool Perfect + PhosFree


    Natural Chemistry Phosphate Removers

    Phosphates can enter a pool from many sources, and when levels exceed 300 ppb, we recommend PhosFree, or a blend such as Pool Perfect + PhosFree, and Pool Magic + PhosFree, to remove phosphates from your pool water. Pool phosphates are a primary food source for algae, and if  your pool opens green each spring, or if you deal with algae blooms every summer, you can test for phosphates, and treat with Natural Chemistry PhosFree, naturally. 


    Natural Chemistry Stain Fighters

    From the very beginning, Natural Chemistry has provided a way to deal with mineral scale and metal staining in pools, naturally. Natural pool chemicals like Metal Free and Scale Free are phosphate-free sequestering agents that will prevent stains by keeping minerals and metals safely dissolved in solution. For all-natural pool stain removal, nothing is closer to nature than Vitamin C, which also happens to be an effective pool stain remover. 100% ascorbic acid, available in Natural Chemistry's Stain Free and Stain Free Extra Strength formulas.

    Other Natural Chemistry Formulas

    Natural Chemistry Instant Pool Water Conditioner, for pools that want to protect chlorine from the sun, but want to keep cyanuric acid levels low. Contains only 1.5% cyanuric acid, yet will register normal tests for cya, and protect your chlorine just as well. 

    Natural Chemistry COVERfree liquid solar blanket, liquid solar blankets use monolayer technology to trap heat in the pool, and reduce evaporation. An invisible layer of natural polymers forms an invisible shield over the water surface to save heat and water. 

    Natural Chemistry Filter Perfect, a natural enzyme based cleaner for all pool filter types. Removes oils, scales and gunk of all types from filter cartridges, sand filter beds and DE filter grids. Natural filter cleaner is gentle but effective, restoring performance to your filter. 


    And beyond Natural Chemistry pool products helping you feel better in the pool, Natural Chemistry pool products are always bio-degradable and environmentally friendly. They won't replace the need for a chlorine sanitizer, but reduce the amount of solids in the pool, removing organic and oily matter, to reduce your chlorine demand, or keep your pool cleaner and clearer, with less chlorine needed.
