Hi Sifu Kit, I've never seen anyone using corals, oyster or even sea shells as biofilter, as ph buffer yes I think the reason behind this is this shells releases calcium and the good guys doesn't like it, me think not sure Anyway, they don't have a large surface area compare to Lava rock, BH/BS or eve JMatt. For good filter you need a good media with a large surface area for the good guys to colonize That's my 2cent worth rgds, Jon "DuKu Friendly" _____________________________________ "No one is ever too old to know better" http://s3.photobucket.com/albums/y63/Koi38/
