    Stain Chemicals

    1. 2 years ago
      Battled fiberglass pool wall mineral stains.....
      Tried Culators, Metal Free, ITS Stain Free, Stain Away powders, etc. then saw a Jacks Blue Magic customer post of similar returning *severe rust-colored* wall stains after few days, mine when chlorination for years and on well water in fiberglass pool. Locals and Internet instructed full pool water drain at $1400 too expensive. So after 2.5 bottles of Jacks Blue magic & BULK citric acid powder combo water & walls clear. Regular treatments of Jacks Blue Magic and light chlorination with ... read more chlorine tabs seem to be effective and persist for a couple weeks now, hope it continues. Be careful fiberglass pool owners use only algaecide 60 plus (no copper), avoid RV antifreeze for line winterization (use legitimate pool antifreeze) due to chemical residue buildup that causes high chlorine consumption and manufacturer says will not subside concentration, and any other copper/mineral products. Will continue to use Jacks Blue Magic as it is only product along with bulk citric acid that has longer lasting stain removal...so far. Citric acid is active ingredient in most anti-stain cleaning powders. Trying small amounts of liquid chlorine now only when needed, hope it doesn't cause re-staining.

      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.

      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.

      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 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!

      Unbelievable
      I tried 3 different stain removers none worked. My stains were a light brown and spreading. Couldn’t understand it, chemicals were in balance. Then I bought A+ stain remover got the bromine down put in a full bottle and the next morning got up to check it out and the stains were almost gone so I put in another half bottle after I swept the sides, the next morning all the stains were gone. Well worth the money, I thought I was stuck with these stains forever. Thank you

      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.

      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 !!!!

      Great for well water
      My well water has high iron content and can oxidize with the shock turning the pool shades of green. This product works great to clear up the water, usually overnight. Much more effective then the MetalOut sold at my local pool supply.

      Actually does what it claims.
      I had staining on both our steps and the liner itself. I thought I probably was going to have to replace the liner. I purchased two bottles of "Stain Away", as a last resort. (I figured it was worth the gamble). Within two days, the steps and liner were free of all the rusty discoloration. I do not know where the staining came from, since we have city water. But if the problem ever re-occurs, I will try "Stain Away" first rather than last.

      Works Fantastic
      We have very hard well water and this product removed all the iron stains within a few days. Made our liner look new again. I always have a bottle to use during startup each year and never had a stain since using this.

      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.

      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.

      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

    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.
