Difference between auxiliary track volume and send/bus

[TyBoMusic]

I'm trying to take it easy on my laptop so I started using AUX tracks for compressors, eqs, etc. that I have on multiple tracks. However, I have a few questions.

When I add an aux track, it is added at -∞. I guess I don't completely understand its function. What is the difference between me pulling this up to 0 or changing the volumes in my original track?

With that in mind, I'm assuming (maybe wrongly) that if I want the full effect/volume to be sent that I set the send to 0 also (the little green circle that I pull up next to the send button).

Am I wrong in any of my logic? I'm just trying to figure out how this all affects volume and what not and what values to set these things at. I had my mix set at individual volumes that I liked. However, when I switched my tracks from all having an individual plug-in to sending them all to a bus, the volumes changed, even when I set the send and the aux track volume to 0.

I know I'm wrong somewhere here! I just don't know where! Can you guys help and point me to a fix and better understanding? Thank you.
