Sorry to hear you won't be coming. I think I met Judy in Japan. Wasn't she with Sharon this past October?

The only concern I have about the porosity of the feather rock is that it may do the same thing as lava rock - Once the pores are filled and the bacteria begin to slough off, won't you lose that amount of surface area, thereby making it much less than desired? How about the media that Aqua UV makes for their Ultima filters? There's supposed to be 700+ sq ft /cu ft of surface?!?!
