Yes, the overflow kit does have the modified Durso, I made sure of that at least
I did want to install a second pump that would run on a closed loop so I wouldn't have to have powerheads hanging everywhere if possible. That's kinda why I thought I might as well exchange this pump for something running more around 700gph then add a second pump say maybe 800-100gph and split that off into four outlets in the tank so I would have a total flow rate of 1500-1700. Anybody think this would work or be a good idea?
I have a mag 9.5 on my 110G now and have to throttle it bad on my sos skimmer box and was going to buy that same pump for my 72 but was talked out of it because the Iwaki are supposed to be better pumps and the mag drives were about $25 overpriced there.
