I have had a 29 gallon for almost a year now, and I have been running without any filter system except for a protein skimmer. I do bi-weekly water changes with 15% volume. I also have roughly 40 lbs of live rock along with 2 bags of live sand.
I also have to agree with the comments on having foam, since they can trap things. I have a small foam piece on the outlet of my skimmer and have to clean it out every week. It gets pretty loaded.
