i fill mine directly thru the net pot & to drain, I undo the top fitting & turn the view pipe downwards, letting it drain off into a spare tub.
It's worth adding an extra grommeted hole in the top for ph'ing between change-outs (make sure it's big enough so u don't drop ur wand in!)
I didn't bother with the fancy airstone holder either, but put 2 x 2" stones in the bottom of each tub - great results.
They really are that easy to make & are far more reliable that drip, nft & aero rigs as they have no internal pumps & nozzles to clog up.
Make sure the airline is opaque btw
respect for a good no-nonsense guide m8.
