New pump and plumbing

I just double checked and it looks like I have 3/4" return lines. Does that change the flowrate?

Google "DCS9000 flow chart" and double check yourself.

So put a 2" long piece of 3/4" pipe coming out of the 3/4" bulkhead. Attach a 3/4" by 1" reducer bushing, slide the reducer bushing into a 1" elbow and run that down to your 1.5" tee.

Or you could use two pumps, one for each side, and throttle them back.

Humpty needs to run a single 9000 at 90-100% for his tank size.

Unfortunately the tank is so close to the wall i don't know if i can fit anything but an elbow on. I will grab a few parts from home depot and see if i can make it fit. If not i will have to go with 3/4" after the 1.5" T, which i planned on putting in between the bulkheads at the same height as the bulkhead and having the tee directly in the middle of them.
Looks like 2-3/4" lines are slightly bigger then 1 - 1" line. I plan on running the pump at 100%.
I pulled out the bulkhead and i definitely cannot fit a 1" bulkhead. Is it common to have 3/4" returns and a 1.5" drain? the 3/4" returns seem really limiting.

Yeah 3/4" is the usual return size.

If you can't fit a 1" elbow behind the tank then put the reducer bushing on the bottom side of the elbow instead and use 3/4" elbow going into 1" pipe.

Ok. So I will keep the pipe as big as possible for as long as possible.
Thanks for all your advice. I really appreciate it!!
