80 lbs is what I bought with the tank. I could easily have more but I don't have that great a bioload (18 corals, maybe 20 inches of fish). I've registered 0 ammonia, nitrate and nitrite since setting the tank up 8 months ago. My Powder Blue Tang is my nitrite-gauge anyway - if he starts losing his color I need to test the water. Hasn't happened yet.
It also depends on how you disperse the live rock in the tank. Good water flow will also help the efficiency of the live rock.
We'll be fighting in the streets with our children at our feet, and the morals that they worshipped will be gone.
And the men who spurred us on sit in judgment of all wrong, they decide and the shotgun sings the song.
