Using Crushed Coral & LR after storgae?

Hi all,

My 80g tank wiped out 6 months ago and a took it apart for storage. I put
the Crushed Coral in a big bucked and the LR in a bucket with tank water.
Now after six months most of the tank water evaporated leaving the LR
exposed to air.

The obvious question is, can I just put the LR in a new set up and wait for
it to cycle. If its now "dead" at least its a bit of rock that might
populate eventually of new LR? Its only 10lbs so I need more

Do you think the Crushed Coral will be OK or will strange chemical reactions
have taken place in the bucket?

I know you guys in the USA might just buy I all over from scratch but here
in the UK this stuff so expensive. LR is about $10 a pound and the 80lbs of
Crushed coral cost me $120

Any advice appreciated.
