      Works great
      This product really takes the rusty looking Material off all my plastic stairs and blow out tubes and filter the only problem is comes back in 10 days to 2 weeks literally just as dark as before but for a week and a half I have perfectly white everything I have tried everything to clear the pool with the exception of one thing which might be the problem because in 10 years of having this house I have never had this problem until last year the only thing I have not done is changed the sand in the ... read more filter in the pump. Which I will do before I get and install this product again. so again it works great I just get it reoccurring and that's the only thing left I think I can do

      Works great!
      Opened our fiberglass pool to metal stains-solid light brown stains everywhere the water was. Could not scrub off so we tried this. Sprinkled it in and the stain disappeared before our eyes. Went trough 2 bottles and had to order a 3rd but worth every penny!

      It worked wonders
      I purchased this item because I couldn't find the stain remover that I had used in the past. I was not expecting it to do much but was extremely pleased with the results. As soon as I sprinkled the powder on the stained brownish color stairs it started working on the stain (from well water and sooo much rain lately). By the next day our white stairs were back to brand new sparkling white.

      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!

      So Easy to Use
      I've never had to keep the pool going on my own before and after ignoring it for a few days during a heat wave found it a radioactive green! I doubled the amount of PhosFree in the skimmer and added a gallon of shock. Two hours later the pool color was back to normal and almost clear. Now I use PhosFree weekly like I'm supposed to and have had absolutely no problems.

      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

      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.

      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!
    3. 1 decade ago
      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!

      Works Great

      Great Product
      This was recommend by our pool installation contractor. We tried the Pool magic and have used it for the last five seasons.
    3. 1 decade ago
      Never will use anything else!
      This product is the best! We fill our pool with well water and it clears it immediately as well as keeps it clean all season. We add it in the Fall and Spring clean up is a snap.

      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!

      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!

      Great Product Does all it Claims to do!!!
      Bought for my daughters pool. She uses it regularly during the summer pool season and simply loves it. It is truly a Great Product for conserving pool chemicals and water temperature.

      The BEST algaecide ever!
      I started using this product about 5 years ago to get rid of a huge algae bloom. Nothing had worked up until then. The SeaKlear was nothing short of amazing. I use 1/2 a bottle every 3 months along with In the Swim super shock and I have the clearest water all the time.

      Algae Problem??? NO PROBLEM!!!
      Been having horrible algae problems for the last two seasons. Tried everything - algaecide, super shock... NOTHING worked. Saw this product, and thought "what the heck...it's worth a shot." OMG ~ so glad I did. Liner is squeaky clean...haven't had that for three seasons! Highly recommend this product. It's been a sanity saver, and we're FINALLY enjoying the pool again.

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

    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.
