Yesterday somebody posted a topic about clams smoking, but just now I looked at my tank and one of my live rock is smoking! (or the looks of it) I can't post a pic but it looks just like the clams from the earlier post, except that I have no clams or shells! is just plain rock! Readings are 0 for ammonia and nitrite and 10ppm for nitrate. No fish yet (they are on their way). Any ideas??? 8O
