If equipment were to count......I just added a Mag 9.5 as my return pump from my 35G acrylic refugium. No ball valve either. Wide open to the return spouts and works great. Roughly 800GPH through the All-Glass Megaflow overflow. That's after a 4FT head. WooHoo! Oh yea, And my ASM skimmer is in the sump and rocking. Pulls twice as much crap as the 220 Super Skimmer did!
