      Good Scum-Ball
      These are comparable to the "sun absorbs" sold. I think they did a great job catching sun tan lotions and skin oils from my pool. 2 of them lasted me all summer. In fact, they still looked good when I replaced the first one 1/2 way through the summer!

      Best filter cleaner purchased
      This product works real well with both spa and pool filters. I have a 9 x 30 pool filter that was very dirty and it cleaned up perfectly in 8 hours.

      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

      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!

      Good product
      This did well on horizontal surfaces but did nothing for vertical surfaces. Next year I will order the Stain Away which is easier to apply and works on all vinyl surfaces within the pool.

      out of this world
      I was HORRIFIED to see our steps turn brown after a bad chemical job. Found this on in the swim and what a relief. Our steps look better than new. I ordered two just in case one wouldn't do it, but it did. And just as it says on the package, it will clean anything in your pool that has turned brown once the water circulates. LOVE THIS PRODUCT!

      Awesome Results
      I opened my pool this year to yellow stains!! I have an 18 x 36 inground vinyl lined pool. I used this product and just like Magic every stain disappeared within a minute where I used it!!! I need to buy some more because of the staining around my drain, but I did use it on my entire stairs, 2 small spots on the liner, and half the drain. So it was well worth the price. I am shocked at how well it worked!! I am extremely excited about my white steps!

      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

      Works great!
      Opened our fiberglass pool to metal stains-solid light brown stains everywhere the water was. Could not scrub off so we tried this. Sprinkled it in and the stain disappeared before our eyes. Went trough 2 bottles and had to order a 3rd but worth every penny!

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

      Great filter cleaner!
      I purchases this filter cleaner for pool closing. In the past, I only used vinegar water to clean my DE filter screens. They had years of build up stains on them. I called and received the MSDS for this product to make sure there were no phosphates that might harm the pool next year or anything that might harm the grass as I was dumping the barrel of water out on the lawn. Everything was safe and the screens look great. There was some black stains from the o ring that remained but after 26 ... read more years, my screens are ready for another year.
