Thanks Carl.

Would probably stay away from rocks cause i do not wish to disturb the
delicate balance I have achieved for my goldies ...

It depends on the rocks and the water conditions you want to achieve.
Most Volcanic rock is inert, and I have not seen changes in my water
chemistry in all different applications form Amazon River to Marine.
Be careful of much Sedimentary rock such as limestone, as this rock can
change your chemistry. Where I used to live in LA most of the rock was
sedimentary and caused changes in water parameters.
Where I live now in So. Oregon the river rock that is readily available
is either volcanic or metamorphic and has not changed any water
parameters.
These stepped red rocks you describe sound like they came from So.
Utah, which is mostly sedimentary and will probably change your water
parameters, (more alkaline).
