Why my pool appears several colors?

If your pool appears green,


algae might not be the culprit. Your pool water could appear to be several colors because you have metal present in the water, which the chlorine has oxidized. So, instead of green algae, your pool could have copper in it. If your pool has a reddish tint to it, your pool water probably has iron in it. Purple or black tints suggest your pool water might have manganese in it.
