lol, its okay to be confused... we enjoy it... jk
Seriously though... when you get liverock, it almost always has some die off... creating an ammonia source for that bacteria that lives within it to feed off of. And the sponges/corals/invertibretes you get hitch hiking on the rock also go through metabolic processes, creating more waste. Which also feeds your bacteria. Once ammonia and nitrites are at zero for a few days... then you can add your clean up crew...
The fluidized bed is unnecessary as well as an external filter... this is where the salties differ from the freshies, and its important that you understand that nitrates are the enemy in marine systems (which the fluidized bed and external filter will make)
BTW have you ever considered a quarentine tank?
