In a pail with some shrimp. Shrimp live and it is not copper. That
would be my guess.

Last line. Chuck it in, place rocks (and I usually raise the water level
slowly as the rock pile goes up so I can keep my forward perspective),
and then fill in with gravel/sand etc.

Yes, but the rock surface must be suitable when applying the silicone
(dry and some gripping texture), and you will be limited by what you can
do with these later on (glued together). I tend to work with horizontal
pieces, working with 3s. Put 3 flat stones down at the same height. Now
a flat stone across these will be flat and secure (tripod). Repeat with
other piles. Now you have 2 levels which are secure. A 3rd level
connects your tripods and continue up from there, wiggling the structure
to test for its integrity. In a 12" wide tank, I can pile rocks to above
the waterline, with no fear of collapse, however it takes a lot of rocks,
half of which are not used because they don't have the right look/shape.
Budget 200lbs of rocks to use 100lbs (I keep a miniature quarry spread
out in old milk crates ;~).

I can't recall either, but I think it is inert. A drop of pH down should
test it, or chip a piece into a small glass of RO and test after a few
days. Maybe someone else can add their experience.

cheers & have fun
