Well, in the example I gave, no, I don't know what substrate they had been 
using before... but that's a good point, if I get any similar compliments 
in the future I'll be sure to ask...

First I just want to say that Flourite is not marketed as a substrate 
additive, it is intended to be used as substrate or at the most a 50% 
cut... it competes with laterite and other substrate additives only insofar 
as it obviates the need for them. With that said, with respect to amount of 
provided iron, depending on which substrate additive you are comparing to, 
Flourite compares at least equally well if not a little better in some 
cases. The main advantage with Flourite is that because it is the substrate 
you are assured of maximum effectiveness through maximum contact whereas 
with a substrate additive the contact might be patchy if not well 
distributed. It is also my understanding (I haven't actually worked with 
the stuff myself) that laterite can be quite messy, falls apart, clouds up 
the tank when working on the substrate, then is difficult to remove if you 
want to replace it.

Yes, I can only speak for Seachem :-). But for us, it depends on the 
product and what kind of claims we make. If we claim that such and such 
product performs better than so and so products, that is based on testing 
we have actually done in house. These performance comparisons are based on 
hard measurable data (e.g. our Matrix Carbon releases the lowest level of 
leachable phosphate, we just measure that in comparison to all other 
carbons, only one variable, very easy to establish a clear difference).

On other products where we don't make direct comparison claims, (like with 
Flourite or Flourish Iron), we just make sure the product performs as it 
should through our own testing, e.g. it wouldn't be wise to put on a label 
"Makes your plants grow 50% more than if you used Product X" as we all know 
from an ongoing thread that it can be very difficult to  control every 
variable and quantitate such things.
