Rocks...

[Pandicorn]

I just found out one of my larger river rocks seems to have some sort of metal or something in it. Safe? Or... It passed the vinegar test, and I boiled them for 30-60 min...

 

[Pandicorn]

Well then I can't answer,

Would only copper be harmful?

 

[Supergummy]

Idk. I just know that copper is harmful.

It's really bad for inverts.

It looks more like flecks of iron pyrite. Copper does not exist in elemental form naturally, it's tied up usually an as oxide or sulfide of some sort. Iron pyrite is ferrous sulfide which is typically insoluble in water but can be oxidized to iron oxides and sulfate compounds. Iron compounds are naturally acidic in nature so it may impact tank pH.

Is this from an existing rock in the tank or one you plan to add?

Been inside for a few days. My tap water is kind of low though, I believe about 6.8...
