Aragonite with Crushed Coral

[AJ_77]

Anyone ever used this stuff: Caribsea Florida Crushed Coral? I got a couple of 5gal buckets of LS recently that I plan to use in the new tank (108), and it seems to be this stuff, or something very similar.

Thing is, it has more crushed oyster shell than crushed coral, so the pieces are a little jagged, but mixed in with what appears to be aragonite "select" size sand - overall, nice stuff. I thought of spreading it thin over the bottom and topping it over with some other sand (but not where the LTA will live - that wil be straight sand). That way the jaggies will be mostly buried. Should I be concerned with these jaggy bits? I could sift them out, but need some input to help weigh the benefits.

Second Q: LS sitting in saltwater at room temp in buckets - bacteria being unusually resilient, I'm guessing by the sea smell (not even gross) that it's still in sufficient populations in there to make it ready for its next tour of duty. Would you use "as-is" and make use of the existing bacteria, getting the new tank off to a good cycle, or rinse it thoroughly and effectively sterilize it?
