About three years ago I bought and set up a 65g aquaplantarium and have recently gotten the itch to try something new. After a year plus of research on terrariums and paludariums I gained enough ideas of what I wanted to accomplish. Although I love the design of the tank it does...
I am rebuilding my 125 terrium into a palidarium with a false bottom and a water falls.
Any suugestions as to what I can use for an inert type of soil that does not clump, mud or silt in any way. I am thinking along the lines of crushed lava rock.
Thanks in advance.
