It's an experimental substrate. It's only expanded shale. I have a 2.5 gallon and I wanted a very very porous substrate to house extra bacteria. It's really helped with water quality. I've let my mulm build up for the plants. They don't really take off till it's established, or unless I fert heavy. The one big draw back to expand shale is that it's light, and easily moved/disturbed.
The first picture is of my expanded shale substrate during the initial scaping. the second photo is six months later, i did remove the black background.
I am waiting for a successful method on breeding Thai Micro Crabs.
