I'm a big fan of the 2 little fishies reactors. They are low cost and run really well. You can control the flow so that the media is just moving a little which is what they recommend. Good phosphate media makes a big difference too. The HC stuff from BRS seems to work a lot better than the other stuff I've tried.
