Tom, I checked Al levels in nearly 25 different substrate materials 
and I would have to agree it's just scuttlebutt. It contains what I 
would call a minimal amount. Some of the other laterites, as well 
as other OTC substrates, have significantly more Al. I would also 
guess Al poisoning is hard to come by when you're a plant. Heck, 
my black topsoil has more Al than AP's laterite. NO VALIDITY! 
(Unless they moved their mining operation to a bauxite pit).
