[You know, every time you write "That's a fact" it annoys me because it
is NOT a fact]
OK, fine, maybe we should define what "we" mean by mud.
When I hear the word "mud", I think of thick, gooey, wet soil or clay. Stuff
that would ooze between your toes if you stepped in it. Stuff that would turn
water murky if added to an aquarium. Is that a fair definition?
When I mix Duplarit "laterite" with gravel, I get none of the above. I
you have never seen Duplarit, to say nothing of actually using it. So I
see how you can sit there at your keyboard and fantasize what it might be.
then proclaim that your fantasies are "fact". Bogus, Steve, very bogus.

Or none, in the case of Duplarit.

I use 1 kg of Duplarit in my 100 gallon tanks. And perhaps we should define
"sand" and "gravel". Sand is what goes in a child's sandbox. It is too fine
use as a substrate except in special circumstances. Gravel, as used in an
aquarium, is typically crushed quartz and has a grain size of 2-3 mm. If we
can agree on those terms, could we please use them?

This fact is not that plain. In fact, once the Duplarit has been in the
awhile AND the nutrients in solution have been carried down into the
by substrate heating cables where they bound by negative binding sites in the
laterite, THEN, if fact, the laterite IS providing nutrients AND in a
manner at that.

OK, fine, define "better". Faster? Larger? More colorful? Cheaper? Let's cut
the crap and say what you really mean.
>You can probably find soil ...
I would rather pay my $50 and have someone else send me a kilogram of
that has been proven to work. I don't have the time nor patience to collect
samples from the four corners of the Earth or even the four corners of Ft.
Collins and try each one under carefully controlled conditions to see what

I'm glad you added the <g> or I would have thought you were serious about
pictures of so-called better growing plants.

I've discussed this fantasy of yours already.

Because then it would not be sticky, gooey, oozy mud, would it? I'm not
mixing some "stuff" in with the gravel but that's NOT what we are
are discussing a MUD SUBSTRATE. Six cm of sticky, gooey, oozy wet soil.
missed that part of the discussion in your fervor to defend your use of soil
mixed with gravel as a substrate?
