At least they *tried* to come up with some rationale for their
system. At the very least the concept of CEC sites seems to have
held water all this time. And since laterite is inert it doesn't
do any harm, so at worst it's an expensive colorant.

sand's contents" It has power". So now you know, it is has
"power" in it:"

TB: "here in the USA, SeaChem developed the use of flourite. Not
that much in either, but its porous nature helps cycle and reduce
some nutrients effectively."
But if everything can and should be dosed in the water column, as
you've said many times, why does this matter at all? With water
column dosing, the substrate becomes a fancy plant holder which,
to me, should not contribute anything to the equation, especially
TB: "While we might get all ticked about someone not telling what
is in it, you might want to take a step back and ask why wouldn't
they say, and what good
would it really do you?"
If it affects the water chemistry in a way that makes the KH
table unusable for example, that would be good to know.
TB: "half baked, etc."
Double meaning there, and I doubt they can really get anything
'half baked' anyway (beyond their 'power' science). It's sorta
like being 'half pregnant' isn't it?
Anyway, I was just using up my snark allowance for the week.
