Metallic veins are usually reflective and actually look a bit like metal. If they don't then they're probably so low in metals that there's no problem. As to any symptoms you might see well I'll be honest and say I'm not sure but I'd check out copper poisoning symptoms.jonnyf84 said:A quick question for Ed, i am about to start a new scape with some local rock, its from Wensleydale so it has a high limestone content, i've run a few tests and everything seems fine. I would however like to know some more on these metalic lines you mentioned, there are darker patches and lines on the rocks but they don't seem metalic to me but i can't be certain, is there any way of testing for metal content and what kind of negative effects should i be looking for that are caused too fish and plants due to this?
