Understanding Mustard Algae: Causes and Symptoms
Mustard algae, also known as yellow algae or mustard-colored algae, is a type of cyanobacteria that thrives in warm, alkaline water. Itâs characterized by its bright yellow or mustard-colored appearance, which can range from a light golden hue to a deep, rich yellow. Mustard algae can grow on pool surfaces, including walls, floors, and even pool toys and accessories.
Mustard algae is often mistaken for regular dirt or debris in the pool, but it can also cause unique symptoms like âmustardâ or âhazelnutâ stains on pool surfaces. In severe cases, mustard algae can even seep into the poolâs plumbing system, causing damage to the equipment and potentially leading to costly repairs.
