Hi Aaron,
Thanks for posting this article. I found it useful for setting up my
560l tank in April last year. Well, i do it a bit different... I have used some kind of clay soil mixed with the Aquaclay ground - Commercial inert substrate, some kind of volcanic gravel coated with clay.
I have used it as bottom layer with ADA Clear super and Bacter 100. I also add a thin layer of potting soil on top. After more then a year it is still good for growing plants.
Cheers
