I've been out of the hobby for about 10 years and I'm currently planning a new fish-only tank with live rock. I really like the look of a tank with lots of live rock that almost reaches the top. I used to have a 58g reef tank and I think It took well over 100lbs (maybe even over 200, can't remember) before I acheived the look I wanted. I am looking at either a 58g, a 75g, or maybe a 72g bowfront reef ready tank. How many pounds of live rock do you think it would take to get coverage all the way across the back and 3/4 of the way up?
