Posted to rec.aquaria evidently no one reads it?
Have since tested all my minerals and so far none have shown any sign
of reaction to vinegar.

Hi,
First time poster to the group and a beginning aquarist. I am
wondering if anyone here can give me advice about using some of my
rock collection as structure in my aquarium?
Specifically:
AMBER
AGATE
JASPER
LAPIS LAZULI
MALACHITE
RHODOCROSITE
SUGILITE
TOURMALINE
TURQUOISE
WHITE QUARTZ

Any information pro or con about these and other minerals as pertains
to their use in aquariums would be much appreciated.

(I already intend to test all of these with vinegar to see if any of
them fizz or not)

Thank you
