Don't need more.
Realize I give advice to specific folks, not in general.I often will not
suggest things on purpose.
I also will not cover every possible senario in one post, we need to hear
back from them first in this case.
I have a good notion of where this substrate "mania" is going.
How? I've had it myself.

This means the tank, no matter how well run with the water column, still
needs iron in the substrate for good growth and health of the plants.
Some plants do fine without any, but perhaps 1/3 do significantly better
with iron there.
I can't see how having a flourite substrate eliminates the

Easy, I have healthy plants, adding jobes, tabs whatever....does not help
improve the growth significantly and later creates a vile mess under the

Well, not with iron, I would not try to do a tank without iron in the
substrate. I've had pure inert substrates for many years.
I know the effects of tabs, jobes etc.

Okay, but now you have switched gears. We do not know if this person has
CO2 or not, I asked and will adjust my advice as I see fit when we find out.
We do not know whether this person has CO2 or not.
But....I'm willing to bet based off all the stuff they have, that CO2 will
be part of the rotuine.
I use flourish tabs in both low and high light tanks and

I am good with the water column, this is perhaps a better place to start

They certainly can see results faster with this method.

At issue is WHY a method works or not. Going back and forth between CO2/non
CO2 is mute till we hear back.
We need to determine what method this person wants to use and their goals

Well it's got plenty of anaerobic and aerobic sites to bind, organic
detritual matter, it builds up over time is becomes more a good sink for
nutrients of all kinds.
Generally I do niot think the Flourish tabs will harm anything, but most
folks have less need for them.
If you have a big old sword, adding one under there may help some.
