Mike, yes it is but I don't want to have my return pump as the source of my water movment in the tank. I believe if I use the sump for mainly filtration etc it will work out well... with the mag 9.5 I'm figuring I'll turn over the tank 5 times an hour which should be good for filtration purposes. For water movment I've not yet decided, I'd like to go with a couple Tunze's but I'm not sure. I could put a couple mag 7s etc behind some of the rock for alot less money and then have a couple of power heads on a wave maker...
