      Wish we had found this sooner
      We wish that we had found this product much sooner. After struggling to keep the water in our spa clean for the first year and a half that we had it, and changing the filter every 6 months or so, we discovered this product. We use this product approximately every six months and have been amazed at how it cleans the filters. After soaking over night filters coming out looking practically new. We have two filters that we have been swapping back and forth for the last couple of years since finding ... read more this product, which has saved us immensely on the purchase price of new filters. Definitely would recommend.

      Great Product
      This is one of the best products I have used to clean filters. Place filters in bucket, add water a LT filter clean, let soak overnight and filters come out like new. Filters that you though were fairly clean come out with dirty water with this product. Soak overnight works the best. Great product!

      EXCELLENT - THE BEST FILTER CLEANER I'VE USED
      I have a Perflex EC65 DE Filter that I bought 15 years ago. I've also used a copper power ionizer in my pool. Through the years I've noticed that time between recharging the DE has become smaller and smaller, and I've noticed when looking through the inspection port that the fingers in the filter were turning green. I've always been hesitant to take the filter apart so I've used other filter cleaners, and by manipulating the plumbing, poured them into the filter housing to clean (boy was I wrong ... read more thinking that worked). Finally, I bought this cleaner which arrived this week. I took my filter apart and was shocked at the clumped, caked DE and dark, emerald green fingers from the copper ionizer. I can't tell you how pleased I am with this cleaner! Within two minutes (NO exaggeration), the tubes were back to white, the copper "plating" was gone. I let the filter nest soak for three hours and rinsed them off. They looked BRAND NEW. This stuff doesn't burn intact skin - (a cut may sting a little) though and completely removes all dirt and scale. WHERE HAS THIS CLEANER BEEN? WHAT IS THIS NOT ADVERTISED MORE? This is THE BEST - PERIOD!! It makes 8 gallons of cleaner. AMAZING STUFF!!

      Best pool filter cleaner
      This cleaner is not only fast, but extremely easy to use. As a business owner, price and effectivness are the main guidelines used to evaluate products. This product works! Having products that are easy to use help tremendously when training new employees. All I need to tell them is to place the filter in the bucket ; remove and rinse it after it changes color. It doesn't get any easier than that!

      The ONLY One that WORKS!!
      I have tried so many cartridge cleaners and NONE OF THEM work as advertised. The result is that I have several cartridges in the 'graveyard', that cost a lot of hard-earned money and are now useless. Then I found In the Swim Granular Cleaner...AND IT WORKS FANTASTICALLY WELL!! Price is reasonable and I will never buy anything else. This is a GENUINE reference!

      excellent product
      this is" the " way to clean media or paper like filters. mine are large and the set-up required a large plastic can to get the filters completely covered by the solution. product is very easy to use and really got them clean. just follow directions on container and i promise your filters have never been this clean. hose off and you are done. excellent, excellent product

      Does the job well
      I've been using this for several year now, and it enables me to get 3 to 4 years out of my expensive filters.

      Better than a product I used previously
      Purge worked beautifully the first time it was used.No ill effects noticed on restarting Spa.All circulating and jet components ran smoothly with no indications of 'straining' caused by clogging.I require a Spa that is able to run continuously without too much 'down time' such emptying and refilling,as my 83 year old bones need the physical and psychological reults it provides.
