What causes colored water?
Colored water results either from algae blooming or the oxidation of metals in the water. Algae comes in a variety of colors (green, yellow, black or pink) and can be found on the surface of the water or the pool itself. Brown or reddish stains are most likely from metal stains like iron, copper or magnesium. This can happen if the pH is off or if high metallic water is super chlorinated.
