      Super Stain Away
      I have been using Super Stain Away for a year or so and It has a big difference in our pool. Previously, we were getting stains in the bottom of our pool (cement bottom) perhaps due to the fact that we have a well. This product has kept any stains from appearing.

      Really works!!!
      My pool walls and bottom was stained brown and went to the local pool store and they sold me 106.00 worth of chemicals that didn't work. Ordered super stain away and it worked overnight. Amazing stuff!! Saved my summer. Thought I was done swimming for the rest of the summer. Was ready to close my pool.

      Eliminated My Metal Problems!
      After redoing my pool, about two months later I started having some stains show up. I did an ID and found out that I had some iron staining. So, I bought Metal Free and the problem went away, but it kept coming back week after week. So, I read some good reviews about CuLator and decided to try it. I bought my first bag and I noticed the stuff inside the bag turned yellow after about a week. I left it in for the month and I was impressed. It took a few bags, and a few months, but my problem ... read more hasn't come back! CuLator says it eliminates the metals from the water and I am a believer! The other thing is CuLator doesn't have any phosphates.

      Worked as described! Great product.
      I bought this a few weeks ago based on the great reviews. We have well water and extremely high levels of iron in our water. I've had it in the pool two weeks now so I won't know how good it is for a couple of weeks yet when I test the water again, but the bag has turned a deep brown and I am assuming it is really working.

      CuLators are great!
      CuLators are a terrific product. I have well water and since I've started using them my pool's metal count has stayed down and hardly any stains.

      For sure Magic stuff!
      I bought this product because we have a lot of iron in our water and I did not realize the affects that has on a pool. I did not know the brand just picked it out. First of all it was priced well based on my search and it worked within a few days the difference was amazing. We converted to a salt water pool - above ground and with the use of this product our pool is the clearest it has ever been. About to re-order for maintenance use now. very pleased.

      crystal clear
      I have been using this product for years in my pool -- just an ounce or two every week and the water is always perfectly clear.

      It's crystal clear which clarifier is the best
      I spent less on clarifiers, but this one is worth it's weight in gold. It works like a gem (Sapphire). Water temperature and/or water ph doesn't seem to affect the workability of this product. Hands down the best clarifier.

      Works when nothing else would.
      If someone told me metal stains were such a problem, I might have thought twice about getting a pool. Seriously, I've got no time or patience for it, and even my pool guy can't figure out what's up. I was just about ready to throw in the towel when a friend recommended CuLator. It's a little pricey, but after the money already spent, what did I have to lose? THE STUFF WORKS. Don't know how, don't care, it just does. Couldn't be easier, just replace the cartridge once a month. Wish I had found this years ago.

      Worked great !!
      We bought this item in hopes to lower our copper levels. And to our surprise it has worked great leap . We put in the 4.0 Culater in the main pump drain, as well as a 1.0 in both our side drains. We had the water tested two days ago and are copper levels went from 0.2. To 0. For the past seven years I have always had high copper levels and now I don’t. I will always have these on hand there’s supposed to be good for 30 days I think

      Works in toilets too
      I actually dropped this in my toilet tank to decrease the rust staining in the toilet bowl. It worked really well. But you have to remove the rust stains in the bowl first. It doesn't remove the stains but the iron in your water

      Really worked
      We had SEVERE staining on our fiberglass pool this spring. I tried other products that slightly faded the "tea stains" but the stains came right back within days. The Blue Stuff made our pool look like new! It took two applications but worth every bit. You must be patient. Give the product three or four days to get maximum benefit and then be vigilant about keeping pool chemicals balanced. We've had no stains reoccur.

      Works, but only
      where water is drained and it is applied to the pool surface full strength. Dropped water below steps, cleaned them great. However it did not get the stains from the bottom of pool.

      A+ Stain Remover
      With some (/much) trepidation, I purchased two (2) containers ($80.00) of the A+ Stain Remover as I was advised thru INTHESWIM that one (1) container only treated 10,000 gals. My inground 22,500 gal pool has shown a 'brown strain' for two (2) years now. Portions of the vinyl liner showed unaffected stained areas where worms had laid but 99% of the liner, showed a "deep brown stain' that was unaffected by all chemical or even high chlorine levels. The vinyl liner was only three (3) years old and ... read more after the first winter showed the 'brown strain'. The pool chemistry was 'perfect' but the stain remained. Today, I received the A+ Stain Remover (only after ordering it the day before) and immediately sprinkled it on the lower steps and in the shallow end of my pool. Within 3 minutes it was noticeable the A+ Stain Remover was lighting the brown stain. Enthusiastically I sprinkled both containers thruout the entire pool and let the pump run. Within two (2) hours the entire pool brown stain was removed or (neutralized) and my liner looks like NEW. THIS product worked for me and was worth the 'expensive' price and finally solved my strain problem that NO other product or service could solve.

      Magic eraser
      I purchased this product to see if it could remove the many nasty looking stains that started building up several years ago in my gunite pool and hot tub. I ordered four bottles to treat my large pool and it was expensive. As I poured in directly over the stains accessible by the deck, they mostly turned a very dark black. I was horrified and tried to brush them away but it did not remove the black. However by the next morning all was well and the stains were gone and the plaster was as white as ... read more it was when the pool was almost new. The water did start looking more green after 3-4 day. Things are back to normal and it was money well spent. The stains in the hot tub made you not want to sit in it, but it looks great again.

      I'm a believer
      I was hesitant to buy this stuff,because of the size of my pool ,I needed 2 bottles....80+ bucks(after tax etc.).It was only after reading someone elses testimonial about A+,that I gave it a try.My pool also had lingering brown stains,that had resisted multiple treatments of metal out,stain remover,algaecide,manual scrubbing,and other pool treatments.I opened those bottles and hesitantly poured the powder in around the sides of my pool,and turned the pump on,it was getting dark so I couldn't see ... read more the results that night,and I took off for work next morning.I got a call at work ,from my wife,so excited that the brown stains were gone!..Thanks A+,and thanks to the guy who wrote the review that gave me the encouragement to try it.After all the money I had spent already in trying to get the stains out ,I wish I had tried it first!and no scrubbing!!

      GREAT SHOCK
      THIS POOL SHOCK IS EXCELLENT. WE DID NOT COVER OUR POOL LAST FALL AND WE STARTED FILTERING LAST WEEKEND BY USING THIS SHOCK. OUR WATER IS NOW CLEAR AS CAN BE. WE HAVE USED THIS SHOCK FOR THE LAST 5 POOL SEASONS AND WILL CONTINUE TO DO SO.

    In The Swim Knowledge Pool: Stain Chemicals

    In The Swim's Dr. Pool

    Stain & Scale Control in Pools

    Pool stain chemicals are an integral part of keeping your pool looking clean, new and inviting. Keeping your pool water balanced and keeping a clean pool sometimes are not enough. In addition to our In The Swim stain chemicals, we also carry Aqua Pills, Jack's Magic, Natural Chemistry, and Sea-Klear pool stain chemicals. There are two types of pool stain chemicals - stain removers and stain preventers, and some that do a little of both. 

    Pool Stain Removers

    With balanced chemistry and a clean pool, stain removers are sprinkled over the surface to lift pool stains. For general purpose organic stains, try E-Z stain remover and for metallic stains try A Plus stain remover. You can also make a Stain Sock by pouring one of our stain removers, or pH Decreaser into a thin sock or hosiery, tied off tightly. Place directly over the stain, moving the location every few minutes, in the pool or with your pool brush. Finally a use for those orphan socks! 

    Pool Stain Preventers

    Commonly called Stain & Scale chemicals, this group of pool stain chemicals is used to keep minerals and metals dissolved in solution. Known in the trade as sequestering agents, they chemically lock-up metals and minerals, so they cannot come out of solution to stain your pool surfaces. Pool stain prevention chemicals include products like Super Stain Away and SeaKlear Metal Klear. Use weekly to prevent pool stains from iron, calcium and copper, by keeping these metals and minerals safely dissolved. 

    Pool Metal Removers

    Sequestering agents don't actually remove metals from the water, they simply keep them dissolved in solution, as long as you add regular maintenance doses. However, major chemical movements or poor water chemistry can force metals and minerals out of solution, where they can stain or cloud the pool water. In such cases, an effective DE or Cartridge filter can remove suspended minerals and metals. One chemical however, CuLator Metal Eliminator and Stain Preventer actually REMOVES metals from your pool water. Place the packet in the cage and drop it in your skimmer basket - absorbs copper, iron, manganese, nickel and cobalt ions.
