Haha oh god, I dont even correct people anymore when they call me Diane. There's been people I've known practically all my life that call me that too, lol.
Yeah travertine is a pretty cool stone, its basically calcium carbonate that has precipitated out of the water and been turned into rock, and all sorts of microscopic bacteria and life gets trapped in it and gives it its color (such as cyanobacteria and spirulina and stuff). Not that it could ever come out of the rock after being fossilized, but its kind of neat having rock in the aquarium that contains the same bacteria from millions of years ago that you are keeping alive today.
Can't wait to see more pics.
