This also looks like a good idea to me. One thing I learned is that at first when my fish were small there was very little debris to deal with, but as the fish reproduced and grew bigger it became a problem. At one point I was cleaning the filter everyday.
My feeling is that a large gravel bed with 3/4" rock and vermaculture will require the least amount of maintenance and provide a great amount of bio-filtration. But sometime the situation calls for a filter and these appear to be pretty good.
