Waterfarm: Waterpump same as recirculation upgrade?

I am going to be running a waterfarm 8-pack on an uneven table that was built to drain in one direction. It's not an extreme slope, only noticeable if you spill water or set things on it. I have been staring at it for a bit, and was wondering if I hooked a waterpump onto the controller outline if it would compensate for the slope but most importantly if adding the waterpump would be the same as the $30 recirculation upgrade. Thanks for the help.
