      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!

      This stuff really works!
      I bought my house more than 20 years ago, & it came with an unground pool. I had no idea how to care for the pool, & had to learn as I went along. At different times I had problems with every kind of algae. I bought a "deluxe" start up kit which came with a bottle of Pool Perferct with Phos Free. I started using it every year and problem solved! I use it every week, & when I first add it to the skimmer & go in the pool it feels like slipping between satin sheets!

      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.

      I'm sold!
      Short version: this stuff works! Longer version: For the past several years I've been opening my 20,000 gallon (w/ mesh safety cover) pool to find it so green and nasty looking (due to the mesh safety cover), that at times I thought draining it might be a better option. That said, I figured I would give this [Pool Magic Plus Phosfree Pool Cleaner] a try, especially since it was still relatively warm when I closed the pool. I did the normal closing procedure, but this time added Pool Magic ... read more too. Then in March, I added a second bottle (as the product recommends). Well, I just pulled the pool cover off and... WOW! This stuff REALLY works! I was expecting to see the usual algae green water that's so dark and 'thick' you can't see the bottom of the pool (or the steps for that matter). However, this year, not only is the water not green but, for the first time EVER, I can actually see the bottom of the pool (even in the deep end)!

      The name says it all! MAGIC!
      We use this product when closing and opening our pool. Before we started using this product we always had a water scum line when we opened the pool. The enzymes in this product break down organics, which prevent scum-line formation. No more scrubby mitt clean-up! This product makes spring clean easy and enjoyable! Highly recommend this product.

      Incredible product!!
      I bought this a few weeks ago after trying everything else first. 2 days after using this product, not only was the algae completely eliminated but the water is clearer than it has ever been ! Highly recommended !!

      Works as described
      One day after adding the green was gone! Extremely happy

      Fantastic!
      This product is awesome. I have not dealt with algae since I first tried this product, 5 years ago.

      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.

      Good product for your swimming pool!
      Good Product!! it's great for my pool and give my pool so hot!

      Good product
      I've been using CoverFree for a couple of years now. While a don't have data from a side by side comparison, the scientific rationale seems sound and the pool does seem warm. My reason for not giving this five stars has to do with shipping and handling. The box arrived wet, as one of the two bottles leaked. Upon opening it I noticed the cap was loose causing roughly 2/3 of the liquid to leak out into the carton. A quick call rectified the matter and a new one was set out with dispatch. One ... read more suggestion...perhaps you can instruct your pickers/packers to give the cap a quck twist to tighten it beore sealing the shipping carton.

      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.

      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........

      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.

      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.

      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!!!

      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!

    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.
