I'm pretty sure I read a post by Ben that said a greenish tint is not indicative of metals. I have no experience in this area but I'm almost positive I read that post within the last 10 days. Brown for iron and deep blue green for copper and whitish scale for calcium.

Also, wouldn't metals precipitate out onto a surface rather than stay suspended in the water? Some clarification on this subject would certainly be helpful to me.

1. Is a greenish tint to the water indicative of metals?

2. When metals precipitate, do they discolor the water, attach to surfaces, or both?
