What are the dark brown and orange spots on the bottom of my pool caused by
January 16, 2023
Dark brown or orange spots on the bottom of your pool can be caused by a variety of factors, including:
Iron or manganese: These minerals can be present in your pool water and can cause staining on the pool's surface. This can happen when well water is used to fill the pool, or if the pH level of the water is too high.
Algae: Algae can also cause dark brown or orange spots on the pool's surface. If the water is not properly sanitized or if the circulation is poor, algae can thrive and cause staining.
Metal stains: If your pool has metal fixtures or equipment, such as ladders or handrails, metal stains can occur when the metal reacts with the water chemistry.
Scale buildup: Scale buildup can occur when the water has high levels of calcium and can cause staining on the pool's surface.
Rust: If you have rust in your pool, it can cause dark brown or orange spots on the pool's surface.
When fertilizer pellets get into a pool, they can cause several issues:
Cloudy water: Fertilizer pellets can dissolve in the water, creating a cloudy appearance.
Chemical imbalances: Fertilizer pellets can cause an imbalance in the pool's chemistry, specifically with pH, total alkalinity and chlorine levels.
Algae growth: The nutrients in the fertilizer pellets can feed algae, promoting growth and making it harder to maintain the cleanliness of the pool.
Staining: Fertilizer pellets can cause staining on the pool's surface.
Clogging: Fertilizer pellets can clog the pool's filtration system, making it less effective.
It's important to remove the fertilizer pellets as soon as possible. Use a pool skimmer or vacuum to remove the pellets from the water's surface. You might also want to consider adding a flocculant to the pool water which will cause the small particles to clump together and sink to the bottom of the pool, making it easier to vacuum them out.
It's also important to test the water chemistry and adjust as needed to ensure that the pool water is properly balanced. It's a good idea to consult with a professional pool service or pool equipment supplier to give you a personalized solution.
It's important to identify the cause of the stains so you can take the appropriate actions to remove them. Testing your pool water, cleaning the pool and testing for the presence of iron and other metals, and using a pool stain remover can help to remove the stains. It's also a good idea to consult with a professional pool service or pool equipment supplier to determine the cause of the stains and to give you a personalized solution to remove them.
