Pool water problems - copper, iron or manganese

Copper, iron or manganese in swimming pool water all cause the water to discolor without affecting the water's clarity much.

Which metal is in the pool water?

Green pool water - usually copper or sometimes iron

Brown pool water - iron (occasionally copper)
