      Great products!
      Great products at a decent price. I don't like the handling fee, but still about the cheapest you can find chemicals with this quality.

      Best I've found!
      We have used In the Swim Shock for many years now. It's always the best value, and works every time.

      Excellent product
      I have been using this product from in the swim for several years now and have absolutely no complaints! This shock is as good as any other I have ever used. It works great for spring opening ! I only need to use one bag in the spring to open my pool and then one bag approximately every week to maintain crystal clear water! Excellent Shock for the price!

      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.

      This product works very well!
      I have had an ongoing problem with staining on my steps. After removing the stains with Stain Free, I dropped the Culator in the basket as directed, and have had no more staining now for three weeks so far....a first!

      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.

      Good product
      We started out using Metal Magic which did a fare job. Then we went to the Jacks Magic The Blue Stuff and it did great, pool was crystal clear, we really liked it. Last month I went to order more of The Jacks Magic The blue Stuff and ordered Jacks Magic The Sapphire and it has done a great job as well. We feel that both of the Jacks Magic products are top notch but on a personal level I prefer the Jacks Magic The Blue Stuff so I ordered two more quarts. Outstanding product

      Worked for me!
      This seems to have worked pretty well for me. Used it a couple of times over the past years. I refill my pool with our well water which has a lot of iron in it. I get stains on my pool bottom and sides. When used as directed on product, this removed nearly all of my stains on my 10 year old fiberglass pool. Package recommends use of metal remover after use of this product. Buy them both at the same time.

      I live in Southeast Texas and in fortunatel got Flood waters in my house and in my pool. It was so dirty couldn't see bottom. After cleaning pool out best I could the walls and bottom had turned green. After about $150 worth of chemicals and a lot of time tried EZ stain remover. After getting the pH of the water correct added this product and to my amazement my pool is now green free nice and clean.

      Works pretty well
      Had stains on my above ground pool liner that went around the whole pool and it came from winter closing, this season was the 2nd time it happened and they were now a lot darker. Had the pool for 4 years prior and no problem - tried the magic eraser - didn't work. Did as was instructed on the bottle and let it sit in the pool for 24 hours and the stains have virtually disappeared. I would say it got rid of 98% of the stains (all are lighter or gone). The only con I can see is it seems to be acid ... read more based so you need to lower the PH which could pose a problem on some pool components along with having almost no chlorine but for the short duration it probably isn't too much of a concern.

      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!

      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.

      Amazing Customer Service
      We ordered this product with some chlorine and shock. We received the chlorine and shock but also received a Magic Jack Tile stain gel instead of this Super Stain product. Called 800 number and explained what happened. As it turns out, they didn't recognize the product we received. Took a picture and emailed it while on the phone. They couldn't find it in their system. So, they sent us the correct product and we kept the wrong product also. I'm sure we can find a use for it. Can't say we've ... read more used this bottle of Super Stain yet, but in the past it has been perfect for our well water and I expect it will be again.

      Excellent Product
      I had metal stains on my pool's white walk-in steps when I opened my pool in the Spring a few years ago. I just poured a quart of Stain Away in the area of the steps with the pump not circulating and let it work over night. The next day the stains were gone. Since then I add a quart to my 25,000 gallon pool every fall when I close and quart each spring when I open my pool. I haven't had stained steps since.

      Worked Where Others Failed
      I have tried a number of products in the past two years to rid my plastered in-ground pool of stains. Most of the bottom in the deep end was covered with a stain, and there were worsening patches on the sides and in the shallower portions. I used a number of metal-sequestering products that seemed to keep the stains from getting worse, but none that would lighten them. After the first application of Stain-Away the large stain was slightly lighter, so I followed up 2 weeks later with another ... read more application at the inital dosage (15 oz per 10K gallons). Then the 5oz dosage for the next 2 weeks, backwashing every other day. The stains have all but disappeared, and the water seems clearer than it has for years! I'll definitely continue to use Stain-Away. I had almost resigned myself to draining and acid-washing the pool before next year's opening. I'm glad that I can forget that option.

      After getting my pool opened and cleaned up, the water was still a weird shade of green, even though it was clear. After some research, I suspected it was excess copper. This got rid of the copper in the water, and the pool is now crystal blue. It didn't get rid of the staining on the stairs, maybe another bottle will?

      Best product I’ve ever purchased for our pool!
      We got some yellow staining in our pool. Our local pool store told us to shock our pool as a first step. That didn’t work, we then brought in a sample every few days over the course of a month. They had me try using a chlorine tab and rubbing it on the staining (which was difficult since it was at the bottom of the deep end). They said if it rubbed away with that it would be organic staining, that didn’t work. So then I bought some very expensive metal remover and sparkle up for after for the ... read more filter. That didn’t work. Then they had me try an Algaecide remover. More $$. That didn’t work. I started googling and came across the A+ stain remover bought two bottles and the next day it was gone! So happy with this product.

      fastanstic
      I thought I wrote a review, but after reading all of them I dont see mine. So here goes, 4 years ago I didnt cover my pool till December and stopped treating it in August (medical problems). All the leaves from all the trees and all the worms were sucked into the pool like a vacuum. When I opened my pool the following April I pulled out over 55 gallon barrell of wet leaves and worms and dead frogs and salamanders. my water looked and smelled like swamp water, you couldnt see more than a couple ... read more inches below surface. Turned on my DEL Ozone Eclipse 20 and used a total of 10 lbs of %73 calcium hypochlorite. Used a "frog log" in front of skimmer so the floating algea wouldnt clog it. I couldnt vacuum because the pump basket would get clogged with algea, it was really bad. Constantly using leaf net to get out all the stuff. I'm telling you this to let you know how bad my pool was. 6 days later my pool water was crystal clear, but you can imagine how badly stained my pool was. my pool is a light baby blue, no design - its fiberglass 14000 gallons which is all well water filled. the stains ranged from light brown (steps) to a darker brown (bottom). waited till my clhorine was 0, i did not add anything for ph, ta , or anything else yet. I always added the %73 cal hypo at night becuase didnt know what my CYA was. I poured some "A+ Stain Remover" on the steps and have a video of the stains disappearing right in front of your eyes. 2 bottles in and 24 hours later pool is crystal and gorgeous baby blue bottom, ALL ORGANIC STAINS ARE GONE. Filled autofeeder /w 3 inch tablets, corrected ph and ta, 1 cup algeacide once a week and my pool stayed gorgeous till I closed it in September. For some reason i am still gettinf leaves and worms in my pool when covered so I still get brown stains but they are barely visible, My wife cant see them. Why there are reviews that say it doesnt work I dont know, but I have given you all the information about my pool and how bad it was and this stuff works, at least on organic stains - leaves, worms and dead frogs and salamders.

      Definitely WORKS
      I had a set of stubborn greenish stains that resisted every treatment. I used the A+ Stain Remover and within 24 hrs they were completely gone. Only negative is the price point. A bit expensive compared to Algeciras and other similar remedies.

      Fantastic
      Bought this 7 weeks ago and has made the pool sparkling clear and easy to manage. I still vacuum the pool every week but have not had to add chemicals at all. Love this

    In The Swim Knowledge Pool: Stain Chemicals

    In The Swim's Dr. Pool

    More About Pool Stain Chemicals

    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.
