you may want to consider a wave maker. I have 4 Maxijet 1200's in my 72 bow with a red Sea wavemaker. It workes well by alternating the flow from each jet. It also has settings for feeding time (turns all pumps off for 10 minutes) and a nightime settings for 8 hour windows.
It works well.
Also, if you want to know what bubbles will do, check out a skimmer. Obviously there will be less skimmate, but do you want that floating at the top of your tan?
