Sandstone?

[buballo]

Can you use sand stone as a decorative stone in a FW tank?

Thanks

From my understanding, you could use SOME (not all). But it will cause your pH and hardness to rise as the common cementing material of sandstone is calcium corbonate. Personally, I wouldn't put it in my tanks.

Thanks all. Apprecite your assistance.
