Drip walls:
I have found myself in a situation after 3 months at this to upgrade my 5gal and 10 gal to 16 bowfronts. My question may be stupid, but I read on here about low flow drip walls.......... what are they ? how do you construct one, size pump ? Anyone have pictures ? I have about a month and a half before I will construct the tanks, so need to know ahead to prepare.
