Help Me Situate My Reservoirs

i got a igloo cooler 2-3 feet from my main res. I have my pump outside both reservoirs and i have the iglo so i can easily check temps/put in frozen water bottles/add nutes while my light is off and my main res is not accessible. The igloo has brought down the temps a lil bit also , due to me not having the pump in either res now....

I want some ideas or pictures on how i should hook up these two res's together. I currently have it kinda Jerry rigged so any input would be apreciated.

I have the intake from the pump coming from the iglo, and the output from the pump to the sprayers in the other reservoir. And i have a drain line coming from the sprayer reservoir going to the iglo.

how and what should i use to hookup the drain coming from the main reservoir, i was thinking some kinda screw on pvc coming from the main reservoir hooked up to a 1in tubing. That way i can easily unscrew it so its easily accessible for empting etc.

anybody got any good pics or info to help me with my reservoir's for my aeroponics.

Some photos and a diagram could be helpful. it sounds like you're trying to do what I WAS trying to achieve but I gave up, n ot due to lack of money but lack in trust of technology to auto level both the coolers without flooding. but.....some photos would be nice.
