I just picked up some at landscape yard, sorry no pictures.
they look like green field stone, but a few have a white vein inside them.
It looks like a glass/silica material.

I will test with vinegar and soak in water and test water, but just was interested
if anyone had any experience with them.

Nice rocks. I love the color of them. Big pieces too!
I have no experience with them, but they will look great if your tests prove ok.

Did you try googling the name?

Thanks for the idea, found this: "Terrapin Green Boulders Ragged-edged green basalt"

Basalt is ok for tank but I still need to know what the white stuff is. I'll start soaking some today and test tomorrow.

also found this,

Since it is formed by volcanic eruptions I guess the white stuff is silica and ok to use.

Good to know. Show us some pics with it in your setup when you can. It's gonna look great.

Good idea. Flip of the ole switch and presto, a new look!

Your have done an excellent job building your light and stand. Great finish color. Very nice!

125 gives you so many options.

With all this fore-thought, have you settled on inhabitants? And who might they be?
Still time to dream and change it up a bit if you choose. :thumb:

It is very common to find Quartz in basalt.

I would say that is what you have there,

Plus basalt is normally a very un reactive rock so you shouldnt have any problems with the water chem.

Looks like its going to be pretty sweet
