Yes I will need a lot of rock to fill the tank and this is only a part of it. I'm getting 450kilos/1000pounds next week and we already have 3 to 400 kilos of base rock here. When I have built the aquascape with dry rock I will cycle it with few hundred pounds of wet liverock to seed. We will probably end up with around 900 to 1000 kilos / 2200 pounds.
We want to have some open areas and not just a tank stuffed with rock back to back
