That's "power" in the sand, as Amano says.
This is preciselty what he is doing.
SeaChem will tell you pretty much everything they are allowed to.

See SeaChem.
Wonder why I am such a hardcore SeaChem guy?
They are open, responsive and non evasive, sell good stuff that works,
responds to the planted hobbyists need nmore than any other in the North
America and now abroad, they will tell you everything they are allowed to
and explain it well, they show up to the AGA events and help the hobby that
feeds them. Leo wouild be proud.

Well, I did indeed test like crazy but now I only need to test what I do
"not" know. So testing for one thing and seeing how it effects things is
But you use to be in the chem industry and I know you'll enjoy messing with
it and then you'll see and scratch yer skull some too and ask the same
things I did.

I wish folks would re read this statement 1000 times. Most assume that the
tanks are all similar rather than seeing if they are or not. This is a
great reason for testing, I learned how to do this with 2 tanks and then
figured out hiow to keep them the same without testing later.
Aftrer testing the water for several weeks(6) and seeing the estimative
index stability for the acceptable ranges I had in mind, I knew the tanks
were very similar.

See how it goes, you seem experimental so go a ahead, try some things, see
how long you can let something go or keep it going.
 You might be very intrested in Edward's post in APC. I'm offering critque
and counter  but I am very very interested in Edward's results and methods.
See prepetual preservation system.

It's all about the rate of input and output.Some things hold the nutrients
longer is all.
Or....ask a question about a substrate and see what they say.
I was certainly entertained by Amano's evasive comments(they come off
funny), but he's doing this business and doing a great thing for the hobby
as well.
No one can doubt him for his influence on this hobby. And this business
also supports him doing wonderful things like lots of neat tank scapes.
