Real rock in the viv...
I want to use some real rock in my viv as part of the water feature. Is there any type of rock that should not be used? I have access to lots of river rock and shale. The river rock I am a little wary of using due to possible farm run off in to the river. Would boiling clean it well enough in case it has been exposed to fertilizers and/or pesticides?

Is it solipsistic in here or is it just me?
