Have you thought about doing any experimentation to see if the use of
the red clay is better or worse than plain gravel or other additives?
This is difficult if you're setting up a single tank, of course.  If
you have existing tanks, how about putting the same plants in some low
and wide pots, one with plain gravel, one with plain gravel and sand,
one with red clay, one with top soil, etc.  See if you can see any
difference in growth.
