I’ve been brewing for a long time and have no idea what you have going on in that picture.
I figured out the trick cooler; very nice.
The three carbouys going to the small carboy has me stumped.
Ah, thats just me being cheap.
Rather than use traditional “bubbler” style airlocks for the carboys, I just use a bung and a piece of hose and put all the hoses into a common container (in this case an old one gallon jug) full of sanitizer.
I have so many carboys that having bubblers for them all gets a bit pricey and hose is cheap.
Like me ;>)
