      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!

      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.

      I can't believe it worked so fast.
      We built a lap pool that is supposed to be enclosed but weather delays have slowed the building construction. We are using the pool like an outdoor pool. I could get the chemistry of the water to acceptable levels but could not get the cloudiness to go away. I could not see the lap line on the bottom of the pool which made swimming free style dicey. In 3 days, all of the cloudiness was gone!!! I am ordering more!!

      Great Idea
      In our California drought conditions, I am trying out this Coverfree product to reduce evaporation from my pool. In the last 2 weeks or so I think the evaporation rate has dropped by about half. So far so good.

      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!

      We are so DELIGHTED with this product!!!
      We added 6oz. to our large pool, during cycling. It conserved water evaporation SO much better than we could have predicted. It got up to 104* for 3 days, then dropped into the high 90's this past week. The pool is in direct sunlight and I would have needed to top it off, at least twice by now. The temperature (no heater) has rapidly reached & maintained a 5-7* increase in warmth. We will be able to use the pool much more often & that makes us happy!! It was a bummer when the water temperature ... read more was too cold & hot outside!! With Cover/free, so far, Sunday to Thursday before a small top off is needed. There is no residue on your skin. No odor. It is important to us that the product is "friendly". A huge plus, is there's NO ugly pool cover & crank to deal with. Leaving a lovely play area, ready for play!!! We LOVE it & will buy it again!

      The Most Amazing Product Ever!
      The thing that makes me so sad about pool maintenance is the fact that this product with some chlorine is ALL I have ever needed for perfectly clear, algae-free water, YET, I spent hundreds of dollars each summer socking the chemicals to my pool to kill mustard algae. If I would have ONLY known about Pool Perfect Phosfree. I will NEVER have to call another pool specialist and pay for their treatments now that I have this amazing product. I tell EVERYONE about it now who has a pool. I actually ... read more look forward to summer now that pool maintenance is a breeze, instead of dreading the inevitable algae take-over. One try and you'll be sold on this product! It's worth every penny and will save you even more!

      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.

      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.

      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. NO ALGEa AND RING DISAPPEARED WITH NO SCRUBBING AND ... read more CHLORINATOR NO longer REQUIRING LOTS OF CLEANING. Even use less acid. Got immediate clear results and took couple months for ring to dissolve. Your sale was a nice break for me, I will stick with you thanks.

      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!!!

      Great Customer Service
      Similar to another poster, I followed the instructions and it clogged my DE Filter. I tried to bump it (it's not bump capable). I wound up having to completely backwash the product out. HOWEVER, I was still pegging a 1000+ p/bb on Phosphates - so I thought I'd give it another try. I called their customer service department to ask how to proceed. Not only did they offer a solution - they provided some free maintenance product after I bring the phosphates down. It always help to call! I'll try and ... read more do a follow-up post after my next batch. Therefore, if you have problems - definitely call the vendor; they appear to stand strongly behind this product.

      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.

      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........

      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.

      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.

    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.
