Re: [APD] New, cheap dark grey substrate

How to resond to this mysterious explanation?

Fuller's Earth *is* a non-plastic clay. [Look up montmorillonite, for 
example.]

Profile certainly is calcined. The manufacturer assures us it is.

The bottom line is that the two products may have some known differences 
(probably due to selective mining or processing), but they are both 
calcined clays of the general Fuller's Earth type. For the aquarist, I 
suspect the only meaningful differences are grain size and color.
