Hi, I usualy use woods in my aquascape and I decided I need some change.
So I got lot of rocks for a new set-up.

I have tested them with muriatic acid to see if they react. nothing happen
Also, I have put them in water and then test after a weak. The PH did not change, The hardness did not change and there is no trace of Fe.

Should I consider I have done enough testing on those to assume there is no risk if I use them in my tank?
Would you check for something else?

Sounds okay.
A good washing etc, there are other potential issues, but you would see some with the HCL treatment, eg copper containing rocks etc

I know rocks well enough to know their geology and by pass such steps.
Local geology web sites can help tell you what's what also.

all I know about geology is that we do have a little of everything here and those two old gold mine at 2 to 5 min drive from town.
What is that copper test you are talking about?
