Building a RDWC out of pvc and 7.5 gal totes in a 4'x4'x80 tent just have a couple of questions. The way I have the tent setup I can only use one of the bottom vents for my intake of 1.5 inch pvc and the return is 3/4 inch comes out the same vent. Questions about the return line do i use 4 ways and raise pvc up so I can make a waterfall into all 4 totes use ball cock valves to control flow than it continues to the inline pump and into the reservoir? At the front I'm coming in from left most bottom vent the tote you can see my feet in what I'm talking about. Frist one will have a valve to control flow can I use a 90 on the next tote or do I need another valve?
Water comes in the front 2 totes and is circulated to all 4 totes and have a inline pump outside the tent to pull the water back to the reservoir and or also have some of that water diverted to create a waterfall in the totes.
Does that sound right? Or did I just confuse the f@$k out of everyone who read this post?
I know it’s a long thread just have questions is all.

Thank you
