      Miracle Worker Overnight
      After a pool party, the pool turned green from algae brought in from guests swimsuits. After being told I may be forced to drain my entire 40,000 gallon pool, to fix the problem, I was also recommended to try Pool First Aid. Overnight my entire murky green pool became crystal CLEAR!

      I Love This Product!!!
      Pool First Aid and has been a lifesaver for us this year. We opened our pool and it turned a horrible brown color-found out the iron was from an old pool ladder we used to have. We have tried over $200 in products since April '07 trying to clear up the pool. All the readings were perfect but it was so cloudy you couldn't see the bottom. Pool First Aid is phenominal the way it cleared our pool. Four days later, the water is crystal clear and the scum line around the liner has begun to disappear. ... read more We plan on using all their products to maintain, close and open our pool from now on.

      Pool Aid
      I have an above ground 18' ft. round pool. Took off winter cover (NON Mesh) and opened up pool as usual. Water was cloudy and dark. Rebalanced all chemicals and got that right but water remained cloudy even after a couple of days. I have a sand filter so just kept sending a few inches of pool water to WASTE (then backwash, rinse, filter) and then replaced those few inches with FRESH water. Did this every other day. Checked water chemical balance daily -- all good. Would maybe only need to add ... read more more Chlorine shock to assist in killing algae, etc. Water still cloudy a week later. After a week of still not seeing the bottom and not wanting to spend $$$$ on chemicals not needed. I tried POOL AID and you should KEEP your filter running!! Do not shut if off. Next morning, saw the pool bottom!!! Dead stuff dropped down so and I vacuumed off to WASTE cycle and got almost all of it OFF off pool bottom! An amazing, quick working, timesaver product! Who knew? Did a second round of Pool Aid (half of the first round)...just to get it crystal clear....I will see it this this afternoon..and I'm sure the water will now be even more clear! This saved me tons of work and buying useless chemicals. I am impressed and would recommend if you do not want to waste time and money. TRY this first! Then see if it's anything else.

      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!

      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!

      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!!!

      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.

      it really works
      If you are OK with waiting a while,Metal Free is a great product...my pool looks brand new(It's 22 years old,in - ground,22x 42.) To be honest,after 5 or 6 days,I thought the product didn't work.around the 7th or 8th day,I saw signs of the stains removal.I would absolutely recommend this product.

      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

      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.

      Works very well.
      Good product. Works very well in our above ground pool.

      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
      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.

      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!

      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.

      Excellent!! Great for FL summer rains too!
      This product effectivly removes phosphates from our water, we only had problem in the summer storm season here inFL, so now we use one at the beginning of the storm season and voila! No more shocking needed! We try to keep it up with regular phos free, but this certainly helps when you forget or are gonna be away!

    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.
