    Stain Chemicals

      Works great for fiberglass pool!
      I've been battling tan metal stains in my pool for the last couple years. The ascorbic acid treatments were getting expensive, and were not a preventative either. This is both a stain treatment and preventative. I tried it out the other day just for comparison, and was amazed that the tan stains were completely gone the next day! It was much more effortless than the ascorbic acid, plus no need to rebalance the pool either. Just pour it into a bucket of water to dilute, pour the mixture around ... read more the edge of the pool, and done! I know that the tea-colored/tan stains cause fiberglass pool owners to go nuts, so if that's you, definitely give this a try!

      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.

      Excellent
      I've maintained a backyard vinyl pool for over 40 years. Five years ago we had to drill a new well and that is when our metal stains started. I've constantly fought this problem since and even resorted to paying for water to be hauled in. I tried this product and it worked immediately. I've tried many other products and this is the only one that works for my pool.

      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.

      Great Product
      The Blue Stuff works great. Had yellow stains on the bottom in the deep end , used this as directed and by morning stains were gone.

      It worked on my fiberglass pool!
      So far so good, I get horrible mineral stains (probably copper) in my pool and have tried many products, some that involve "Sequestering the minerals" but it always seems to come back and often all at once in a big splotch. This product seems to have worked just fine, what a difference. Love my fiberglass pool, don't even need algaecide and very low chemical cost.. I think I found my stain remover of the future, if I ever need it again.

      This stuff is amazing
      Our pool is near a lot of Japanese Maples and even with a leaf net, debri gets to in to the pool. Once the leaves were gone and net removed I cleaned the pool. But for the first time, the pool walls and bottom were a brownish, yellow color and brushing and shocking it would not remove it. At first I thoguth it was algea and tried an algecide. This did not work. I have used other stain removes from In the Swim but thought I would try this new product. I was amazed. Only hours after putting it in ... read more the water the stains are gone. The water is crystal clear for the first time in over a month. Great product!

      Miracle product
      I was extremely skeptical of this product but I had really ugly stains on the bottom of my fiberglass in the ground pool. Really in the scheme of things 88 dollars is a small price to pay for the removal of those ugly stains. My pool is 12,000 gallons , so it took 2 jars of A-1 stain remover. I put the first on in and left it over night. The stain was very light but still visible, so I put in the other jar and let it do it's thing over night. The next day the water was very cloudy and you could ... read more not see the bottom. The next morning the water was clear and every stain in my pool was GONE. The pool now look's brand new. This stuff work's great !!!! You will not be disappointed.. You will probably need a chlorine neutralizer to get your chlorine level down to 0,3 but after the level is down, the product work's GREAT !!!!

      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.

      Amazing
      After converting from a solid winter cover to a mesh trampoline cover several years ago started seeing stains from dirt, leaves and worms getting under the cover during the winter. Tried other removers without success. Followed the instructions and my liner looks new again with all the stains removed. Amazing!

      E-Z Stain Remover
      I purchased this product after doing a bit of research to find a product that indicated it would remove the stain on my pool liner. I had my doubts. I followed the directions to the letter to ensure E-Z Stain would had a chance to work. To my surprise after I cleaned the pool a couple of says after application the stains that had been in the pool for 3 years were gone. Excellent product.

      Not quite there
      We used this product in our 20 x 40 i ground pool but it only took out about 60 or 70% of the stains. Perhaps I didn’t mix it enough but I’m pretty sure we had the PH & Chrorine at the right levels for putting this cleaner in. We’re probably going to give it another try...

      Easy to use
      Good price and easy to use. Worked very well in my salt pool.

      works as advertised
      I used this together with Jack's Blue pool stuff! Both worked GREAT! My pool steps are back to white. instead of grungy brown. Our Water softener failed and we didn't know it. So each time we put water into our pool, we were dumping iron contaminated water in. Was a nightmare, but in just under 24 hours, these 2 products cleared things up. NO dropping chlorine levels, just use as directed.

      Good Only When Needed
      I only use a 68% calcium chloride when opening my pool and after adding water when back washing my sand filter to keep the hardness in check. My local pool store sells bags of this for $0.99/lb. Works great as a shock but even after mixing and pouring in front of returns, the water remains cloudy. Muriatic acid brings the PH back in line and removes the cloudy look. The acid adds to the expense and its another chemical I don't like to store with young children. If you test your water regularly ... read more and keep everything balanced there is no need to use a shock. During the summer I only add 6% liquid chlorine that the local pool store sells for $0.99/gallon. Liquid chlorine will not cloud the water and has no other ingredients to upset my pools chemistry.

      Pool shock
      This pool shock worked okay I use it for opening my pool in spring for some reason that no one can tell me why it takes cases and cases of liquid shock to get the water to read any chorine on the test strip so this year I mixed the shock some liquid some granular it still took a whole lot of shock

      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

      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

      It worked!
      I had iron stains on my pool liner from using well water. My first attempt to get rid of the stains worked but then they came back in a couple days. My second attempt included using the CULator and the stains did not come back! I am so relieved to be done with that problem.

    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.
