Ziss ZB-200F Moving Bed Filter

Having just recently purchased this filter I can't speak to long term performance, but so far, I love it. It does require more air to run than a traditional sponge/poret filter, and it might be ever so slightly louder than a sponge/poret filter, but I like that it offers some flow and with the low PPI sponge on the intake, I'm fairly sure this will require less maintenance/cleaning than a standard sponge filter.
