No, not more effective. Sponges can harbor massive amounts of bacteria for their size, with ease of maintenance. Just squeeze them out in a bucket of tank water. This is just one reason they are so popular with discus hobbyists. If you are doing proper water changes, massive filtration is not needed on a discus tank, unless it is way overcrowded.
