Im interested in building my own DWC system out of a sterilite tub. I've been reading lots of members post about the DWC system and know pretty much all the basics of it. I do have a few questions though that keep coming to my mind that i can't seem to find answers for. If these questions were asked before i apologize.

1: On the dwc system, how do you "top off" or even flush and refill the tub? Im sure just taking the lid off or pulling one of the netpots out to refill is not the best way. Has anyone ever made one of these tubs with an inlet for filling and a plug on the bottom for draining?

2: Keeping water level at optimum level, how to tell where the water level is? Do i just lift one of the netpots out to check water levels, or is there a way to make a water level indicator without having to open the tub? Sorta like on the waterfarm.

3: How many netpots and what size are ideal for a 10 gal tub or 18 gal tub?

I think those are all the Q's i had, if there are more i think of, i will post. Once again i apologize if these questions were asked before. I made a quick digram in photoshop of the system im thinking about, would this work?
