Not to jump on in here or anything, but I was also wondering how you should face the powerheads to generate a nice flow. If there is a difference between how one should direct them with a wavemaker (one of the over-glorified off/on timer power-strip type deals), or without said wavemaker, how would you do it for each? While I'm on the subject, (and sorry I forgot to mention, I'm way new at this stuff) what do you smart people think about those wavemakers? =] Thanks!
