How much base rock, how much live rock?

id go 50/50 on that and get half live rock and half base rock. also, maybe im wrong here, but 110 seems like a lot for a 55 gallon.

How much base and how much live is purely a financial decision.

If you can afford all live then go for it. If not then yes, the base rock will become seeded- in time.

FWIW I have about 50-60 lbs I don't need sitting in a bucket in my garage. Coming to Ft. Lauderdale anytime soon?

Wierd...

I thought I had made a post on this subject. It's gone though, so either I forgot to actually hit submit or something else happened to it.

Something like 2lbs per gallon but I don't know so?

Long story short, my reading online seems to suggest that you need less rock if it in more porous. Surface area counts for live rock. A few varieties of live rock are even recommended online at rates as low as 3/4 lb per gallon, while TBS recommends 2 lbs per gallon. I'm personally going with 1.5 as my own rule of thumb as I set up my tank (as I am also a newbie).

I'd just say to look at your rock. If it is as porous as tufa, you don't need so much. If it has less indentation or is really dense, you'll need a lot more. If it looks like a chunk of quartz, I don't think it's very useful.

Live Aquaria lists about how many lbs per gallon you'd want with a few varieties of liverock, just to give you an idea. The denser it is, the more you need by weight. I'm currently looking at Premium Aquatics as a potential source for my live rock, because the shipping would be less for my situation and I've heard a few good things about them.
