One question for your guys - if I take the exact same bioload from a 55gal and move it to a 120, would I maintain my exact same dosing amounts? I was thinking YES, because although I'm changing my total water volume, I am not changing the amount of organisms that will be extracting the elements from the water column.

No, it's about the PPM. If a coral needs "X" PPM for efficient element uptake and absorption then you need to up your dosing. Even Salinity doesn't put your Ca, Mg, and Alk at perfect numbers. (They would sell a lot less dosing product if it did)
