Stains Behind The Liner
Some stains are actually behind the liner, in between the wall or floor and the liner. They start as a bacterial colony or can be algae or mineral crystals. If they are dark enough and large enough, they may show through the somewhat opaque pool liner and appear as a stain.
Short of pulling up the liner and treating or patching the floor, and foaming the walls, what can you do when the stain seems to be behind or underneath the liner?
Start with the methods above: good water balance and give a heavy chlorine shock. This may only work temporarily. If the stains are near the waterline or high on the wall, you can lower the pool water and get at the wall with a scraper, then place a barrier in between the wall and the liner.
How To Prevent Pool Stains Before They Happen
It is much easier to prevent pool stains than it is to remove them. Pool owners who practice good pool maintenance usually have far fewer stains to deal with. Here are some helpful tips for preventing stains in your swimming pool:
- Always keep pool water balanced, including chlorine levels, alkalinity, and pH levels.
- Frequently skim the pool surface to remove debris that may settle to the bottom of the pool and cause stains. Empty skimmer baskets regularly.
- Run a robotic pool cleaner or manual vacuum regularly.
- Test your water for metals, and use a metal sequestering agent to remove any metals that are present.
- Keep pool equipment and plumbing well-maintained and free of corrosion to prevent rust stains.
When you understand the different types of pool stains and what causes them, you are better equipped to treat them and prevent them from recurring.

How To Identify Pool Stain Types And Colors:
- Organic stains: These stains originate from the tannins in leaves, dead algae, plant debris, small animals, or other organic matter. The stain colors range from yellow to brown to black. If the stain lightens from a small application of chlorine on it, the stain is organic in nature.
- Mineral and metal stains: Too much copper, iron, calcium, or salts can all result in pool staining or marks. Too much copper usually results in blue-green staining, while iron results in red, yellow, or brown stains. Calcium and salts can result in white deposits. To test for metal stains, apply a small amount of vitamin C powder to it. If the stain is from metal, it will fade or disappear.
- Fading: Vinyl pool liner fading can also be an issue pool owners will face. Fading can occur from the use of pool chemicals or from the sun. Low pH and high chlorine are both common reasons this occurs. Fading is not treatable, unfortunately. However, it can sometimes be prevented by always pre-dissolving granular chlorine in a bucket of water before adding it to the pool.
