How many lbs of Live Rocks?

[TygGer]

What is the general rule of thumb for the amount of live rock per gallon of water?

Thanks

I think it really depends on the type of rock. Right now I have 100# of Lr.com in my 90, which filled up my 55 perfect. I need more for the 90. The rock is very dense and weighs more then say fiji which is more porous. I would say that 1 # per gallon work for filtration, but for looks I would go 1 3/4# to 2#.

on average most reccomend 1.5-2 pounds per gallon

I tend to suggest closer to 1lb - 1 1/2lb per gal. Depending on the density of the rock it might be physically imposslbe to put 2lb per gal in a tank.
