SPS Flow

[kl3377]

I have finally begun stocking my 35 gallon cube (20"x20"x20") with SPS and Zoas and wanted some feedback on my flow. My return pump is a Gen-X Mak4 pushing some where around 800 gph after factoring in head pressure. The return pump also feeds 160 gph to my UV sterilizer. So I figure I get about 640 gph entering my display which is split in to two lines using a T and LocLine. I also run a Jebao RW-4 on Else mode. I feel like I have plenty of flow but was curious if my numbers back up my belief. I also wonder if, in anyones experience, I should be using a different mode on my RW-4. Thanks
