Removing Rust Stains from your Pool

Each product has its own benefits, but no matter which you choose its best to completely remove the metal ions with CuLator to be sure that you are eliminating the risk of staining.

Note that these products arent meant for stain removal, they are meant for removing or binding metal in your water before it stains.

Sequestering/chelating agents can be used in conjunction with large stain removal so that as the ions are freed up they are bound by the agents and cant redeposit. We also recommend using CuLator in conjunction in order to completely remove the metal.

Can take time to fully remove metal ions

Embrace The Sock Method

Most pool owners have probably heard about the sock method as an effective technique to remove rust stains. But do you know how to use this method?

First, wear protective eyewear and gloves because youre about to deal with harsh chemicals. Once your safety is in check, take a clean sock and add a cup of granular acid such as sodium bisulfate, also known as dry acid, to the sock.

You can also use ascorbic acid in place of sodium bisulfate. Tie the sock tightly to prevent the acid from getting out.

If the stains are far down at the bottom of the pool that your hands cant reach, you can use a pool pole to lower the sock and hold it over the stains.

Do this for about five to fifteen minutes, checking often to see the results. Be careful not to leave the sock on the stains for too long since it may lead to a reverse stain. A reverse stain is where the previously rusted spots become brighter than the surrounding areas.

Fixing A Swimming Pool’s Metal Stains

Swimming pools with water sourced from a well are prone to developing stains due to the presence of heavy metal compounds like iron, copper, silver, and manganese.

Oxidized iron turns pool parts and water to a brown or rusty color, copper turns pool parts and water to light green, silver turns pool parts and water to black, and manganese turns pool parts and water to purple.

Metal stains occur mainly when chlorine is added to water, oxidizing these heavy metals to produce different stain colors, depending on the metals present in your water. These stains might occur at different places inside and around your pool, including:

  • in the pool water
  • along the bottom or walls of the pool
  • along a vinyl liner or on fiberglass surfaces
  • across the steps or on various pieces of pool equipment

In this article, we will break down how to:

  • test the water for metal stains,
  • get rid of metal stains in five steps, and
  • prevent staining in the future.

Add the acid around the perimeter of the pool and set your filter to RECIRCULATE, or if you have a cartridge filter then you can just remove the cartridges and let the water circulate.5. Brush the pool to stir the acid.6. Run your pump for about 2 hours.7. If the stain hasnt disappeared, add more acid or let the pump run longer. You can also brush stubborn areas to help the acid penetrate the stain.8.

    Re: Algae Or Stains In My Gunite Pool

    I have exactly the same problem. I had some staining when I inherited the pool with a new house. I got a lot more last year when I switched to Baquacil. I learned too late that a metal problem may occur with Bacquacil, and Iâm assuming it is metal, but I donât know. The gunite seems pitted at the stain, as it is rough to the touch. I donât have a test kit yet, so canât give numbers. I did have an algae problem, which has cleared up with Bleach treatment. Now I only have the yellow stains, and a few rust marks left from nails I found in the pool when I bought the house.Any help in removing either would be greatly appreciated.Thanks!

    How To Get Rid Of Organic Pool Stains

    As the identification test indicated, chlorine is the solution here. But because the amount you use for regular sanitizing isnt enough to remove stains, youll need to super chlorinate the water. To do that, youll use pool shock.

  • Test and balance the water: Use test strips or a liquid test kit to ensure the alkalinity is between 100 parts per million and 150 ppm, which 125 ppm being ideal, and the pH is between 7.4 and 7.6, with 7.5 being ideal.
  • Shock the pool: If youre dealing with just one small stain, a regular dose of shock should take care of the problem. But if you have multiple or large stains, to get rid of them with just one round of shocking, use a triple dose. This means adding 3 pounds of calcium hypochlorite shock for every 10,000 gallons of water.
  • Brush the pool: Use a stiff pool brush to thoroughly scrub the stains. Its OK if you dont remove them completely at this point.
  • Run the pump: Allow the shock to circulate throughout the pool for at least eight hours or overnight.
  • Brush the pool again: During those eight hours, or the next day, scrub the stains again.
  • Check the stains: Are they gone? Great, youre done! Are they still visible? Repeat the process.
  • Important: Remember always to shock at dusk, or at night, for best results.

    Note: If youre not sure of your pools volume, you can use a pool calculator to figure it out.

    A small swimming pool stain is usually caused by a metal object being left on the plaster bottom long enough to rust and leave a stain. Most metals, when subjected to swimming pool water chemicals, will react and leave a stain where they were in contact with the pool’s plaster. The most common objects to stain swimming pools are soda or beer cans, pop tops, and coins. These items can cause a stain as quickly as overnight. That’s why it is important to remove any metal objects from the pool as soon as possible.
