It's not just about adding pounds of liverock to an aquarium, it's more about the type of liverock that you will use.
If you put 100lbs of dense heavy and non porous liverock in your aquarium, it's not going to be as efficient as 30 lbs of lets say nice porous Totoka liverock. I have zero nitrates in my aquarium and I have about 45lbs of liverock Totoka in my 70 gallons tank. It does the job very well because it's so porous so deep inside it also denitrify.
So it is best to have porous liverock that weight not much vs heavy dense stuff and the weight you will need really depends on that.
