How much rock do you use?

I personally find the "pounds per gallon" rule as useful as the "watts per gallon" rule

The old school thought is 1 pound per gallon of mixed salt water in your tank and not the total capacity of your tank and sump. so a 100g tank would get about 85-90 pounds of rock. you can have more but less if you are going to heavily stock is frond upon, as the rock will not be able to keep up with the bio load demand.

I think surface area is probably the more meaningful metric so while you're waiting for the water to clear, measure the volume of your rock using the Archimedes principle and then measure the surface area of said rock and let us all know the results. The method for measuring surface area is left as an exercise to the reader. Bonus points if you somehow use a laser. Extra bonus points if you use a blue laser. http://www.thinkgeek.com/gadgets/lights/896a/

Less then what is recommended. Believe I have about 80LBS in my 105G. I like the more open space look.

1.5 lbs per gal would be OK if you could set it up in a sump. Way too much rock in the display for my taste .

Just to be different, I like lots of rock. Never been an "open" look fan. I love full reef tanks. More rock, better filtration, just need to make sure enough water movement and placement to allow for such. I can say for a fact, most fish we keep, including the cruising tangs, love lots of rock and hidey places. Anyways, just a different opinion to the mix.

I don't pay much attention to how much rock I use. i just 'scape it 'til I like it. Probably about 1 lb per.

I scaped my tank to how I like it which is less that the pound per gallon. But I filled one of my sump chambers with rock. I don't know how much I have in the tank but it probably worked out to the "pound per gallon rule".
