Types of Stains in Swimming Pools

Stains can be caused by various factors, including organic and inorganic substances. In this article, we will discuss the different types of stains found in swimming pools and how to identify and remove them effectively.
Organic Stains
Organic stains are those caused by living organisms or natural materials. The most common organic stains found in swimming pools include algae stains, leaves and plant stains, and rust stains.
Algae Stains
Algae is a microscopic organism that thrives in warm and poorly maintained water environments. It can quickly spread throughout your pool if not properly addressed. Algae typically appear as greenish-brown spots on pool surfaces.
To remove algae stains from your pool:
- Brushing: Use a stiff brush to scrub the affected areas vigorously.
- Vacuuming: After brushing, use a vacuum cleaner specifically designed for pools to remove any loosened algae debris.
- Shock Treatment: Add an appropriate amount of shock treatment chemical according to the product instructions.
- Algaecide Treatment: Apply algaecide directly to the affected areas as directed on the product label.
Leaves and Plant Stains
Leaves and other plant matter can leave unsightly brown or greenish-brown stains on your pool surfaces over time.
To remove leaves and plant stain from your pool:
- Skimming and Netting: Use a leaf rake or skimmer net regularly to skim off any floating debris.
- Brushing: Gently brush stained areas using a soft-bristled brush.
