I have a dart gold blasting through my 150. Way too much flow for a return, but picks up all the detritus pretty well. I'll keep it this way until I decide to cough up a bunch of money on some wave makers, right now I'm using 3 kora 4's. I like it for now, and my coral loves it, only reason I'd like to change it up is to stop some of these micro bubbles in my tank.
