Causes of Rust Stains in Pools

Before we tackle the stains, let’s understand why they form in the first place. Here are some common culprits behind those stubborn rust marks:

  1. Metallic Pool Equipment: Metal components such as ladders, railings, or screws, if not properly maintained, can corrode and release iron particles into the water, leading to rust stains on pool surfaces.
  2. Irrigation Water: If your source contains high levels of iron, it can oxidize when exposed to air and sunlight, resulting in rust stains when the water comes into contact with pool surfaces.
  3. Fertilizers and Yard Debris: Rainwater runoff from fertilized lawns or yard debris containing iron can find its way into the pool, causing unsightly rust stains.
  4. Corroded Pool Heater: A corroded pool heater can release iron particles into the water, contributing to staining.
