Check out this link to Emperor Aqautics. They have a acurate flow thru guide that will halp you determine your flow rate. http://www.emperoraquatics.com/SMARTUV_Instructions_07.pdf
I will say that the amount you will pass thru a 57 watter is no where near 3500 Gph. Determine what you are looking to control(water clarity, parisites) and then adjust your flow accordingly.
