iwaki pump

Hi All, I have my sump in my basement. My tank is 220 gal and my sump is 60gal. (I have 3 x Nero7 in the tank so no need for alot of return power) Im pumping about 10 feet up and about 15 to the side with couple of elbows. I have been using VectraL2 but its always on full and barely making it...
