Reef Octopus Varios 4 DC pump

I was thinking of buying this pump with the controller, but it doesn't state what each increment is in gph, just the max @ 1050gph. Anyone know the gph for each increment?
Thanks

The gph will depend on the back pressure, and that depends on your specific plumbing.

I will give you an example from my system. I have a Vaios 2 connected with 1/2” flex tubing to a UV sterilizer and with a 1/2” flow sensor on my apex. The steps are approximately 160, 180, 200, 220, 235 gph.

Thanks. There won't be much head pressure, it will be going into a rear sump ( 3/4" connection to a "T" reducer both ends from there go to 5/8" dual nozzles at each end return - total height 10") on a SCA 66g custom built - 32" x 24" x 20", rear sump 32" x 5" x 20". I'm just guessing here but total output of Varios 4 - 1050gph = approx. 210gph per increment = 210 , 420, 630, 840, 1050; However with only 10" of height but with reducing connector from 3/4" to 5/8" for 2 nozzles probably more like 200gph increments - 200, 400, 600, 800, 1000 ?
