Planet aquarium return question

[stinkydavis]

I am wondering how it is possible to get 2500-3000gph return flow when it’s got 2 3/4in bulkheads. I turned my 5200gph pump to the max and still only got about 700gph out one line. Is this even achievable?
Thanks in advance!

Im running a 6000 gph return pump and have 734gph of actual flow which for me is perfect

So do you have an individual pump to run your UV sterilizer then? Assuming you have one I guess
