Does mustard algae eat chlorine?

What is it? Mustard algae is a chlorine-resistant form of green algae that often resembles dirt or sand on bottom or sides of pool. It contains compounds that act as a defense mechanism against the oxidation efforts of sanitizers, helping it survive even in highly chlorinated conditions.
