I have a question that’s been on my mind for some time.

Let’s say someone has many many live rocks and a deep sand bed (for denitrifying bacteria to turn nitrates into nitrogen gas).

and let’s say this person needs to dose nitrates because their levels are too low...won’t increasing the nitrates cause the denitrifying bacteria to increase their population size? In turn requiring more and more nitrates added to maintain the same level?

I would suggest there is a limit. As it is you need a lot of live rock and/or DSB just to account for regular feedings. Certainly doable but I would not be concerned with it being a neverending cycle of needing to dose more and more nitrates because the capacity of your rocks and DSB to handle nitrates is limited.

The denitrifying bacteria population can’t keep increasing unchecked because of limited space and possibly running low on some other nutrients.

That's possible, but denitritifaction is often organic carbon limited, not nitrate limited.

The denitrifying bacteria consume nitrates though?

Do you need a DSB for mud? I know mud has benefits to phytoplankton and releases nutrients for things like soft coral and macros
