how much gravel should i use in a rbp tank?

I go for about 2-4" but some like more or less, I say enough to plant your plants, but not too much because it will just get dirty.
You can also go for the sand option.

well for piranhas it is not important to have excess gravel as you should for cichlids that tend to dig alot. So an inch or two would be adequate

It really depends on what you like. I would use a minium of 1". I personally use about 2"

1 lb per 1 gallon,
150 gallon tank = 150 lbs of gravel.
just my opion

That's a bit of a crude calcaulation...
I mean, coarse gravel will weigh less per handfull (more air between the stones) than a very fine gravel...

i use @1-2'' of gravel easier to clean and looks just right
