3 bucks a pound? Forget the dead stuff, get all live! The more LR
you have the faster your cycle will be. It sounds to me that, and I may ahve already forgotten the size and I'm guessing wrong, but you have a similar sized tank taht I started with, which is 36. I threw 50 lbs of LR
into mine and once I got the cycle started it flew. It was just getting it there due to Fedex murdering my box and there being little die off.
As for live sand...every person ehre will tell you that there isn't anything live in it. I agree with this. That sand has been locked up in a bag, air tight, and sat on a shelf. The only thing I like about it, and why I bought it, is because I thought it was cool to have sand with beat up coral and shells in it.
As for the dead coral, yes it will become live again upon being in the tank witht he LR
, sand, and/or just the cycle in general.
