I'm running three k-4's on one end of my 120 blowing at various angles but in the same general direction and the wp40 opposing them on w1. I only run the wp during daylight hours (not sure why just like the idea of it) and all is well. When it comes on it stirs up spots and gets the gunk flowin thru water column and right into the filter sock. I will say that it seems to grow nuisance algae much quicker than the k's, probably because it rests overnight??
