What were you originally using that made the marks? I REALLY like how your system looks, btw, the blue inthe tubing is super neat. I would like that way more than that ugly yellowish color.

with corrosion you'd see either a white or blue/green precipitate form on the surface, because corrosion is a chemical reaction and breaks down the materials into other compounds


but brown marks on copper is just tarnish, so no worries
