      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!!!

      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.

      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.

      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!

      Pool savior
      I have been using Metal Free for several years now and it is an outstanding product, it really helps to keep the copper stain away from our fiberglass in-ground pool. In addition, the price that In the Swim charges is much lower than local pool stores and the product arrived the next day! :)

      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.
    3. 10 years ago
      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.

      Fabulous product
      I have bought many many products over 15 years to get rid of algae on our pool walls. Brushed the walls regularly. This product WORKS. It Cleared the pool and it has been clear for 2 months. I love this product.
    2. 2 years 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.

      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.

      Crystal clear pool on spring opening
      We've been using this product for 3 years (after a horrible experience opening our pool) and we wouldn't close or open our pool without it now. Great product.
    3. 5 years ago
      Works Great
      This well be the third year that we are using POOL MAGIC. Pool has been very clear each spring opening

      It worked!
      I bought this as we have had a cold summer. My 3 year old granddaughters birthday party was to be a pool party here. I put it in and with clouds and mid 80 temps it raised the temp of water 5 degrees in 4 days. All the kids had a blast. So I am sold on this product! Well worth the money!
    2. 7 years ago
      good product
      I've used this for the last summer season and already using this summer . Really holds the water temperature even through the nights. No evaporation and I recommend it. Buy here..cheaper than pool supply stores...

      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!

    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.
