The garnet sand is beautiful. Where did you get it?
I have panned for gold only to come up with pans full of garnet. The mineral is hard and quite stable and is usually among the last minerals to break down under near-surface conditions. It is perhaps not as stable as quartz, but then little else is.
I can't really guess at what the stones are, but basalt would not be my first guess.
How do you intend to plant the tank?
