I feel your pain, Suzanne! Been there, done that. And this is usually how I discover it's time to replace/repack the filter stuff in the iron tank as well. When our water comes out of the ground, I swear it's almost sludge.
I know where you live Winger, it is sludge from all the iron mills in the area.
