      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........

      Great product, poor shipping
      Product removes metals from pool water. Especially useful for use when topping off water line with hose. I am on a well and it definitely works. Poor shipping. Last order I made had empty bottles due to shipping department not taping lid shut and product emptied during shipping.

      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

      Works wonders!

      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.

      Works fast
      Works fast when I put it directly on the stains, like magic. I love the ascorbic acid power.

      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)!

      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!! 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!

      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.

      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!

      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.

      Great product
      Ive been using pool perfect +phos free for 6-7 yrs now. No algae and the water is crystal clear all season. Every spring when opening pool water is clear, just turn on pump and pools ready.

      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!

      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.

      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.

      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!

    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-Zymes™ 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.
