Hi everyone. I KNOW how stupid this sounds, I do. But, can you keep gem stones in your tank? Nothing metallic. Just glass types like Emeralds, Rubys, Amethyst? I know it sound crazy, but I was thinking about a buried treasure themed set-up. Would it matter if these stones are raw or polished?
ALSO (for a different tank) ....
I know that driftwood is not a good idea for SW tanks. It will lower the PH. But is there a way to treat the wood so it would be safe to use (in smaller amounts) in a SW tank? I heard if you let it sit for a while in water it would help (salt or fresh?). Im looking to have a few sticks coming out of holes in a piece of live rock (with a cup coral on top) to use as a feeder station for the seahorses.
