Red-Brown Pool Water

Red-Brown Pool Water

A reddish or brown tint in the water is due to iron or manganese. Iron can exhibit brown, dark red, or a black-brown color in the water. Manganese can show as a brownish-black color in the water. This can happen due to the source of the water filling up the pool or it could also be due to the erosion and or corrosion of circulation components, including the pump. Manganese may be present as a result of source water contamination or the use of certain water treatment chemicals. To remove the red-brown tint from pool or spa water, a sequestering or chelating agent is added to the water to tie up the metallic ions and reduce the possibility that they will stain surfaces. The filter should be operated to assist in removal of the suspended materials. After 24 hours the water should be retested for metals.
