      DE Filter Cleaner
      My filter kept clogging up and returning greasy substance back into pool. I used this cleaner to soak my filter grids. No more problems.

      It worked!
      I used this product, one 2 lb. container, in my 25,000 gallon pool. I did not use the Metal free as instructed and my pool liner, return lines and skimmer were cleaner than they had been since I can remember (our pool is 29 years old, the liner is 13 years old). I did need to apply a month later and now it needs to be done again. But I will try the Metal free with it the next time. But for only $30.00 I was quite satisfied with the results.

      5 Year Old Liner Looks Brand New!
      Each summer start up, we have brown and yellow staining on the hard plastic surfaces such as the skimmer and steps and the liner has a dull brownish tint. We used Ascorb-X one year (which was a super product) but isn't as "environmentally safe" as Stain Free and is no longer sold. You must be sure the chlorine is low to apply this product or it will not work. If your water balance is good and chlorine low...the results are amazing. Don't be dissapointed if you don't see a change right away. Ours ... read more was significantly stained and after about 12-18 hours looked BRAND NEW! We added clarifier at the end of 24 hours and the pool is beautiful!!!!!

      stain free tm
      I had a very interesting time trying to get my pool to shine, sparkle and look inviting untl I found STAIN FREE it's just like Putting Vitamin C in your pool water. Just lightly sprinkle the C all over the pool and watch it litereally eat away all pool stains. It leaves your water crisp and clear within a few hours and makes swimming the ultimate because of the conditioned water. I recommend everyone to try Stain Free at least once. You'll never go without again! Thanks, Paula

      Nature 2 is the best
      The most important purchase I make each year is a nature 2 replacement cartridge, it keeps my pool crystal clear all summer long.

      Great alternative to chlorine
      This product really cuts down on the use of chlorine. I use a lot less now and our bathing suits last longer and no more burning eyes!!!

      What a difference
      Install once a season. No chlorine smell, skin dryness, and other problems associated with chlorine. Still need to shock pool every two weeks and set chlorine feeder on 1. $100 to $150 savings every season too!

      Eliminated My Yellow Algae
      We have a 15,000 gallon 16 year old concrete pool that needs to be refinished because it has corroded over the years from chemical use which creates the perfect environment for algae growth. We had mustard algea pretty much everywhere with a concentration on the sides and steps. The Super Algeacide and Super Shock totally eliminated it! It took a lot of elbow grease (brushing and vacuuming), but after a couple days and almost the entire bottle of Super Algeacide over the course of thee days, it ... read more is gone and has remained gone! Last summer I spent much more $ at our local pool supply store buying products to eliminate the mustard algea. Great product and great price!

      The name says it all!!
      Fastest working clarifier I ever tried! Great for those times after a hard rain when small debris clouds up the water or when ground dirt gets into the pool. My pool is surrounded on three sides by woods so if it works for me, it should work for most "normal" pools. I also use it a day before having people over to give the wafer that great shine we all look for.

      I absolutly love this stuff. Our pool installer came back to check on our pool and was impressed at how pure and clear the water was!!

      Works so well!
      Having been a pool owner for many years and having tried numerous products, this clarifier is the best by a country mile. You have to have some patience in this instantaneous world but leave it for 24 hours and you will be thrilled with the results.

      I discovered Natural Chemistry products years ago, and I swear by them. I had a pool place trying to tell me I needed new filters. This was after Hurricane Ike, no, went to another pool place and they sold me the clear perfect. Next day pool great!

      Quietly Working
      Like most chemical products, Salt Water Magic seems to work as there are no negative effects to the pool. That being said, with the extremely high evaporation rates this year in the southern US, then need to add fresh water to the pool has also forced me to add bulk pool salt in addition to the Salt Water Magic treatments.

      Excellent Product
      First time use was after installation of our new in-ground pool. Supplied to us by the contractor. Our salt-water pool is low maintenance and high usage. Add this product once a month and we are good to go all summer.
