What does algae look like on pool walls?

Algae growth on pool walls may take many different forms and colors depending on its species; below are some typical traits:

1. Green Algae: Green algae is one of the most prevalent forms of pool algae, often appearing as patches or streaks on walls in either light to dark hues with patches having fuzzy or slimy textures.

2. Yellow/Mustard Algae: Yellow algae often resembles a thin, sandy layer when found across pool walls, and its light hue makes it harder to detect than its green counterpart. Often found in shaded areas or where circulation of water is poor, yellow algae often forms in shaded places or places with poor water circulation.

3. Black Algae: Black algae often forms small dark spots on pool walls and surfaces. Its distinctive appearance often resembles small black dots with greenish or bluish hues that may recur over time. While black algae is relatively simple to eliminate from porous pool surfaces, its deep root structures often make removal challenging.

4. Pink/Red Algae: Pink or red algae may be less prevalent but still appear. Usually appearing as pinkish patches on pool walls, steps, or other surfaces; pink algae often forms slimy coatings and can resist chlorine treatments.

Note that algae growth depends on several factors, including infestation severity, maintenance practices, water chemistry and more. Regular pool maintenance including proper filtration, circulation and sanitation practices will help prevent future algae blooms and keep walls clear.
