What is the black stuff on seams of your pool?

Algae is the most common cause of black stuff on pool seams. Algae is a type of plant that grows in water, and it can thrive in both chlorinated and saltwater pools. Algae can be unsightly, and it can also make your pool water feel slimy.

Dirt and debris can also accumulate on pool seams, and this can create a black or dark brown buildup. Dirt and debris can come from a variety of sources, including leaves, grass clippings, and dust.

Rust is another possible cause of black stuff on pool seams. Rust is caused by the oxidation of iron, and it can occur if there are any metal parts in your pool that are not properly protected.

Chemical imbalances can also lead to black stuff on pool seams. If the pH level of your pool water is too high or too low, it can cause the metals in your pool water to corrode, and this can create a black or brown buildup.

Biological contaminants: Pool water can also be contaminated with bacteria, viruses, or fungi, which can cause the formation of black or dark material.

Pool construction materials: Some pool construction materials can also be susceptible to discoloration or staining, leading to black stuff forming on seams.
