Pump for rdwc

Hello, I am new to rdwc and this is my 1st system. I think a 1100gph pump is sufficient but Need input from the community. Here’s whats going on.....
6 site + res 20 gallon totes w negative flo going thru a 1/2 hpchiller w flow rate of 850-1600 Gph, the piping is 3” from res, thru the totes then down to 3/4” tubing thru pump into chiller then to res
They will be in a 5x9 gorilla tent w the exterior room set @ 73. Going to pull air thru a carbon filter set on the outside.
For lights I have 2 12 bar led 720w, the lights are 39”x39” and brute as can be.
My questions are these...
Will the water,piping and totes being 68 degrees of set the heat coming from the leds? Don’t really want to run co2 if the exhaust is going to constantly be working.
Also is my 1100gph pump enough flo?
Will have another 1100gph pump for a 12site waterfall(2 per tote)

Is the 1100 just to circulate through the chiller? That's probably a bit too much. The 700gph mag drive I run on my 40 gal UC system runs through a 1/4hp chiller AND waterfalls to each tote(4). A single pump does it all.

1 1100 for the waterfall and 1 pulling water thru the 6 totes @ the end and back thru the chiller and into the res.
The res w have a float valve and top off res also

Are you suggesting pulling from res thru chiller and then waterfall?
 
My outside res. 450 gph pump through 3/4" line pumps out of res, thru the chiller, and dumps back into the outside res. This setup cooled 150 gallons fine.
800gph pump feeds back to 6 17 gallon totes.
2x 2" drains in each box keeps everything nice and level. I ran as much as 2400gph out to 12x 17 gallon sites and they all stayed level with passive drains.

I love that new setup. Waterfalls opposite side of pot, plumbing tight against the wall. Jealous.
Need to re do mine.
 
Why'd you use those rubber couplings? For easier take down? I only ask cause it seems like after the second union, those 2 90's would make that res return pipe a bitch to clean. I'd think there'd be another 2-4 more unions at least. One right after the 90 with the union already at least.

Thats just where I removed the other half of the system. I cut out the 6 on the right side and slid the 6 from the left side to the center. Couplers were just to put it back together without cementing. More so I dont have to cut it if I ever decide to put the other 6 back in.
A dryer vent brush that goes on a drill with the bristles trimmed up a little bit is all thats needed to clean inside the pipes at nearly any angle. Everything is reachable by brush. I just made sure that worked, I havent had to do it yet though. The several day long peroxide flush between cycles has kept everything super clean.
Having the space to get in the tent to work is amazing. I can actually sit on the floor next to the boxes to do trimming and stuff instead of having to hunch over them and shit while squeezing between rows.

So the other 6 totes aren't being used? Why you downsizing that area? The bulkheads used on those other 6 just lyin around then?

yeah the 2 rows of 3 are just stacked up off to the side. They were put together with my diy fittings too.
I just dont need 12 plants for personal use if im going to do something of a perpetual grow. I want it to take up more of my time so im just doing smaller crops year round instead of 1 or 2 big ones.
 
My idea is to put a shut off valve a the end of the pvc close to the res and a filter after then to the chiller and back to the res.
Each tote will have 2 waterfalls opposite end of water flo and of course nothing but 3” tubing.
The waterfalls will also be powered by a 1100 gph pump
 
My next question is should I hand water my clones(in Rockwool this time unfortunately) until the roots run out of the cube or just set the water level below the cube and run w it?
