Note the spelling, Robert F. It is "Flourite" and not fluorite.

Folks tend to drop the quotes that should always be used on Trade Names 
and I may be the only one still doing it. It *is* a bit of a bother.

Properly it could be considered a crushed terra cotta or ceramic, since 
it has been fired and fused together. You are right, in that it is no 
longer clay. Unlike "Profile/Turface" which is a fired Fuller's Earth 
product, Dr. Morin has not chosen to share with us the exact kind of 
clay used as the starting material for "Flourite."

No argument, there.

But "Flourite" is a trademarked product of Seachem, and a very popular 
one, here. Personally, I think it is great, and wish shipping to the 
Left Coast didn't price it out of reasonable range. I used to get it on 
sale from Pets.com for $10/bag with free shipping. [That may be why they 
aren't around, now. ;-)]
