In my 29 I have a mj 900 with rotating deflector and a mj 600. I also have a sump with a magdrive 700 return pump but I've choked it down a little. I turnover roughly 27x/hr
I upgraded my power head in my tank to a RIO 1100. I also have 2 submersables another rio800 with a hydor on it, its choked off a bit. And the other is a small maxi jet circulating behind my LR.
