Too much time in my head?

Still at the planning stage for a few tanks in preparation for when I move so I'm doing A LOT of research so when the time comes, I know what I'm up to.

Anyway, been thinking far too much about the substrate (as you do) and for my main 6x2x2 community, I plan to have 1.5" MTS mixed with a clay based cat litter (20%) and topped with an inert river gravel type of about 1". There will be a 1" border of inert substrate round the front and sides of the MTS for aesthetics.
From what I read, 1.5" should do me as I'm only planning moderate planting:- iro 50% visible substrate initially, not taking into account further growth, CFL Lighting and Yeast CO2.

I was wondering if having a thin (1cm-ish) sponge/filter mat layer beneath the MTS would help prevent anoxic conditions and/or possibly serve as a nutrient reservoir for the roots to tap into? Or, as I suspect, am I overthinking this?

I don't think there is much to worry about with anoxic/anaerobic decomposition in such a small volume. The plant roots will help bring oxygen down.

Even so, I'm not sure there is really much material to get the really toxic gasses - I think the most common is H2S (I think Walstad's book covered how plants can counter the production/accumulation of it, but I don't have it on hand to check), and I don't think dirt has excessive sulfur in it (not certain) for this to be that much of a concern.

Even so, I'm not sure how sticking a sponge underneath would help, I think it would just add to the substrate volume without really giving you any benefits?

Don't forget the roots would grow into the sponge under the soil making it even more difficult to remove plants and/or rescape.

Ok, thanks. I'm trying to overcomplicate things as usual
