NOTE: I no longer use pumice filtration (although it kept some of my tanks clean for months between media uncloggings). This is just because, following my shift to exclusively bowls, I no longer need the capacity. Many people have commented on why they hate this video, so you can read and judge for yourself. While my experience with pumice has been good, I'm no longer going to respond to any comments because I think we've discussed this enough, but watch and comment with others if you wish.
