How long have you had your other 50lbs of rock? I assume it's functioning as set-up display with live stock already? If you're still in the cycling stage you can just go ahead and toss er right in the aquascape.
Since you're likely not, I gotta ask you to ask yourself is it worth it? Were you looking for more rock before you saw the $2 deal? Is it a good deal? If you're not in process of cycling already it could be more work than is necessarily worth it.. You would have to isolate this rock to a container, like mentioned above, with a strong circulation pump for around 6wk-3 months depending on how you go about adding the rock. You likely could add all 50lbs at once, but if there was any die off it may be so much it could cause a new cycle in your display... bad... So you may have to add slowly.... And remember you need to top off this container with freshwater... Those of us with ATO may find this annoying.
How far away is this guy? Sometimes a craigslist deal has you dropping $40 in the tank to even get it. Turn that into shipping. Here's what I'd do. I'd head over to bulkreefsupply and check out there dry rock that's between $2-$3(and higher) a pound... Theres other dry rock suppliers as well, I preferred brs... With dry rock you do not have any of the dead organics as you do with the old rock... Major benefit. You will not have the aged algae look though, but I view this as a good thing.. Overtime this rock will naturalize its look in your tank as it grows coral/algaes. Dry rock will also more easily allow the colonization of nitrifying bacteria for filtration as all pores are open and not filled in with old matter.
You can also put this directly in your tank without having to deal with the curing process. It is also likely going to run you the same ballpark, and you're going to have the ability to choose exactly the type of rock you want. There's some sweet tonga shelfs
that enhance ANY aquascape.
