1.  Not sure at all.

2.  I have gotten good results thus far(better than the tank without any laterite 
    after 2 months or so.
3.  I have Dupla in one tank, Thiel in another, and none in one.  The results are 
    equivalent to Dupla thus far and no where near as well in the tank minus a 
    substrate additive.

Substrate in all tanks with and without laterite is Texblast sandblasting grit.

BTW:  Thiel screwed up my order the first time.  I ordered directly from them 1lb. 
of the chunk form(which is really more like a bulky powder).  In the mail, I 
received the POWDER form!!  I was sorta mad and let them know about it and they sent 
me 1lb. of the chunk form free of charge.  I was pleased with the response needless 
to say.
