say you have a DWC setup with netpots in like a rubber made bin, when you go to change your water what is the best way to remove the remaining water in the reservoir without disturbing the plants too much? do yall just take off the netpots/plants and dump it out? or have a open close valve at the bottom or something like that?

also in a flood type system do you need an airstone or something to give the roots oxygen when they're flooded? or do you not in a flood/drain system where the roots are not submerged in water 100% of the time?

anyone have any good hydro diagrams? I get how most setups work and all Im just not that technical and dont see parts of things and things that have to be done and why clearly.
