Hi everyone, I'm new to calculating head pressure and stuff for a 40B + 20G sump. I thought I had it down at one point but then I looked at different calculators and it threw everything off so I don't know what to believe anymore. I want it to come up from my sump then split off so it shoots back in my display tank from both the right and left side of the display tank. My stats are

Pump: Quiet One Lifegard Pump 758 GPH 1" MPT
Vertical travel: 4'
Horizontal Travel: 3'
90d Elbows: 8
90Degree T-Joint: 1

How do I calculate head pressure?
Is a 1.5" diameter overflow enough or should i do 2"?
Is the Uniclife DEP-4000 a better option?
