      Great product for those who are < perfect w/reg ma
      I've used this and the stand-alone PhosFree for the last 2 years. The PoolPerfect is great when used as part of your regular pool maintaince routine. Or even if you miss a regular maintenance period. Keeps the water clear and phosphates at bay even with our pool. It's a 33,000 gal pool that gets sun all day long which is murder on the cholorine levels in the summer. As often happens with life- we occassionally miss a weekly maintenance and as long as I've been using the PoolPerfect my ... read more phosophates and algae are kept in check. For pool opening season we use the stand-alone PhosFree to get the phosphates to zero (one treatment per bottle instructions is all it usually takes). Then use the PoolPerfect to maintain.

      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!

      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!

      Wow, the stain is gone
      I had to put a lot of well water into my pool this year. It left a brown stain on the walls and floor of my vinyl liner. I followed the directions and sprinkled the product into the pool onto the stains with the pump turned off in the evening and the pool chemicals at the levels indicated. I saw immediately there were dots where the product started working on the stain. I went to be hoping that it would at least get some of the stain off. When I went out in the morning the liner was a vibrant ... read more blue and the stain was 99 percent gone. Except for some spots on the walls and in the corners. I am putting metal free in today and will probably repeat the process just to get the very few remaining spots. Very satisfied with this product.

      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

      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.

      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.

      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!

      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.

      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.

      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
      This was recommend by our pool installation contractor. We tried the Pool magic and have used it for the last five seasons.

      The name says it all! MAGIC!
      We use this product when closing and opening our pool. Before we started using this product we always had a water scum line when we opened the pool. The enzymes in this product break down organics, which prevent scum-line formation. No more scrubby mitt clean-up! This product makes spring clean easy and enjoyable! Highly recommend this product.

      Openings are great with it used at closing
      Just like the review title states. Openings of my 30,000 gallon pool is easy and great with using this product at closing. I also used it at opening. I didn't get algae grow at all this late winter to opening at the end of May and I live in western MD. I will purchase again in the fall for closing and one bottle used in late winter and then for opening.

      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!

      Phos Free is a must to pool owners
      I had a pool build last year. I struggled with yellow algae to the tune of over $1,000.00 in a course of two months. I couldn't use the pool most of the summer. I went to several pool stores to purchase chemicals. I used banish and all sorts of things. I close pool for the winter and started over this year. To my amazement, finally someone told me about Phos Free. I mean in a matter of two days with a 20x40 pool and 16oz of Phos Free my pool is perfert. No more algae. I can't begin to tell you ... read more how fustrated I was. To anyone out there, I promise you; this is the best thing since the microwave.

      PhosFree Believer
      9 year user. Got first sample from my pool builder. I hate the dangerous chemicals in algaecides, and don't like the foamy water, algaecide taste or water ring from dead algae. Open pool with shock & algaecide. Vaccuum and clean the waste. Balance pH, test phosphate. Use phosfree if elevated, then weekly phosfree + pool perfect. Keeps water sparkling with no foam, no water ring and no algae, even through August. Will occaisonally add a dose for unusually hot weather or a lot of rain. (I don't ... read more find the spring / fall treatment to be useful. Even with use at recommended dose, still need algaecide to open.)

      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.

    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.
