Ocean Clear filters

[dennisdeng2002]

I just picked up 2 filters and I'm wondering what kind of backpressure these produce, IE in terms of head height? I had originally opted for a pressure rated pump, but I got a great deal on a Iwaki, but it turns out it's flow based.

I have a 325 OC on my QT and the gage is at 2.5 psig, ie about 6' head ( 0.434psi = 1' head). Working fine with my Iwaki MD20RLT.
