Black or White?

Man, Ok, I'm now confused. What you say makes sense I guess.... But I've heard, from several different sources, that you shouldn't use ABS for your piping. I always bought that line, because, AFAIK, ABS is not rated as OK for potable water. So, if it's not safe for us, it's not safe for our reefs, must be the reasoning. I've only ever seen ABS used in waste water situations (sink drains, toilet flanges, drain stems, etc.) Actually I'm not sure that all PVC is rated for potable ... some pipes have "potable" printed on the sides whereas others do not.
