Ok, I've always heard that you want to go 1-1 1/2 lbs per gallon when you're getting live rock. But when I was looking at TBS's site their "package" (http://www.tbsaltwater.com/package_chart.html) is always 2 pounds. That doesn't sound two bad, but 40 lbs of live rock would have filled my 18 gallon to the top, and if I started up a 90 gallon tank, isn't 180 lbs way too much? Is Tampa Bay's rock simply denser than what I'm used too? I've got mostly Tongan in my little tank now so I'm not sure as to the difference.
One more question, if the rock is really similar, couldn't I go with something like the 60 gallon package instead? That would be cheaper and would still be 120 lbs of rock.
Thanks!
Brian
