"Show off you T5 run (non Zeovit + similar) SPS tank please"
So I think my tank meets the restrictions described by the OP.
FTS (form last November)
My Sunset Millie
ORA Pearlberry
Keylime granulosa
I set this tank up following the KISS method. I have never run a Zeovit or other system (i.e. a supplement regime that involves a bacteria reactor) I also have never used vodka... But in the past I did try dosing prodibo bacteria and then at one point I dosed NB7 (bacteria only)... I have since stopped "regularly" dosing all forms of bacteria. I will add a couple drops of (leftover) NB7 every other month or so, but by all means this is not a "carbon driven bacteria system".
Honestly, When this tank was set up, I thought it would be a "carbon driven bacteria system" but after trying it for a bit (Probido then NB7) it became apparent that the dosing regiment did not significantly benefit my system.
