Akadama will allow the roots to perforate the clay and as such it will break down after a few years.
Give it a try and see

according to the advert it said it is High fired, which had me worried at first as i believe the Akadama is not so I wasn't sure if this product is suitable or not.
Also BrettS tried some crushed brick and stuff as well.
try to find the old threads and see what they suggested.
