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

      Phos Free is a must to pool owners
      I had a pool build last year. I struggled with yellow algae to the tune of over $1,000.00 in a course of two months. I couldn't use the pool most of the summer. I went to several pool stores to purchase chemicals. I used banish and all sorts of things. I close pool for the winter and started over this year. To my amazement, finally someone told me about Phos Free. I mean in a matter of two days with a 20x40 pool and 16oz of Phos Free my pool is perfert. No more algae. I can't begin to tell you ... read more how fustrated I was. To anyone out there, I promise you; this is the best thing since the microwave.

      Finally!
      With arthritis, we keep our pool warmer than the average pool. This results in a struggle with algae. Our pool has been either green or cloudy most of the summer- yuk...and we have spent hundreds of dollars on chemicals. This would have been tolerable if it had resulted in clear water. I even replaced fairly new filters, thinking this may be the answer. I saw this product and thought the mechanism of action seemed logical. Well, we now have the clearest water we've had in 7 years! I anticipate a ... read more great decrease in the cost of operating our pool....and it is beautiful now.

      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.

      We have very hard water and Scale Free helps to keep the buildup down on the sides of our pool.

      Openings are great with it used at closing
      Just like the review title states. Openings of my 30,000 gallon pool is easy and great with using this product at closing. I also used it at opening. I didn't get algae grow at all this late winter to opening at the end of May and I live in western MD. I will purchase again in the fall for closing and one bottle used in late winter and then for opening.

      BY far the best thing ever made
      i close ALOT of pool here on the nj shore...As long as there is no algae when u close the pool, adding this bottle will keep it that way. Ive even added it to pools with some algae at the closing and the pools opened MUCH better then expected. i HIGHLY reccomend ALL of natural chemisty's products. The "Pool perfect +Phos free" weekly during the summer will make your pool the nicest in town.. besides no algae, your filter will stay cleaner, no scum lines, and the water feels like silk.. i really ... read more cant say enough good things about this company... Check out "nature 2" products as well... ANOTHER great product!

      Amazing!!!!! Life Saver!!!!
      This is the greatest pool product ever! My pool was in bad shape last fall & I closed it without any treatment. This spring it was even worse! I thought I would have to drain my pool and start over. My pool "professional" even said it would take at least a week for my water to clear up enough to see the bottom of the pool. He gave me a regime to follow and said to call when the water was close to being clear. I put the 1st Aid in, and the water not only cleared up in a day and a half, but in 2 ... read more days it was absolutely sparkling! I called him and he didn't believe me! The water looks better than it ever has! My husband, who hates the pool, was even impressed!

      Best Purchase
      I have been trying for 2 months to clear up our pool. Nothing had worked until I tried this product. Our pool was blue but still cloudy and the more chemical we put in the worse it got until First Aid. I can now see the bottom of my pool!

      On Well Water, Use Metal Free
      I battle with the water in my pool for 3 weeks before I found Metal Free, the very next day we were in the pool and cooling off. Works best in combination with a water clarifier and balancer (lower the ph). If you shock well water it turns coffee colored, then use the 3 items above and it clears the water and test in the medium range for all strip tests.

      A pool must have with well water
      I make sure this is on my pool supply list when I open my pool for the season. It works wonderfully in my inground pool, especially on the stairs. We have community well water in my area and we very easily can see the yellowing caused by the water. It spruces up my pool in no time. It is very easy to use.

      Great product
      Using well water rich in iron to fill or add water to the pool causes the water to turn brown when it comes in contact with the chlorine Metal out has worked great to clear this up almost overnight will continue to use this product as needed to keep pool water clear

    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.
