Standard procedure after some disasters I have had with rocks.  I now soak it
in a pH 7.0 tank for a week, noting the GH and KH at the beginning.  I check
it after 7 days, and compare "before and after".

My thoughts were to mix it with  laterite and possibly also sphagnum peat (I
tend to keep South American dwarf cichlids and tetras.  They like the effects
sphagnum has on the tank)

It comes in light tan and also a light reddish tan (I suspect the latter may
contain some iron in its crystalline matrix).  Those are the only two colors
