Should I use 2 filters?
I will be coming directly off my sump with a Speed inc. 100 micron fliter, then into the 420L. Should I add another 1-10 micron filter after the pump for better filtering? I deffinatlly want something in front of the pump, but wasn't sure if the 100 micron would be sufficent. I couldn't go any smaller on the first filter due to pump cavitation.
