      clear cloudy pool
      Got about 1 month. I am satisfied with the product
    2. 1 decade ago
      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!!

      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.

      Works well
      Very good product to use with Solar Sun Rings. In these drought conditions I'm saving many gallons of water. Evaporation is about 75% less than without these products. Also $10.00 less per unit than the swim centers.

      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!

      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.

      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.

      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.

      Cheap chemicals
      Phosfree worked great, we've had a pool for over 33 years , Never had to worry about using phosfree until the last few years.chemical companies are making the chemicals cheaper with phosphates thus costing us consumers money.Also watch out for cyanuric acid if this is to high you will have to drain your pool to get rid of it.its on tablets and shock.

      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)!

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

      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!

      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.

      Stain Free
      Works great. Highly recommend it for difficult stains. Made our pool look new again.
    3. 2 years ago
      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.

      Great Stuff!!!!
      Best stuff ever, cloudy water or green water it will clear it up with in a few hours or over night. Also added some to the pool right before closing and it kept the water crystle clear all winter long, opened pool in the spring and it was fabulis.

      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!

    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.
