Rock out of water what to do

[xtreeme]

Hello, been a while since I have posted.
Friend gave me some rock he took out of the tank. This rock has been in bucket dry for long time it white. I put in some hot water to clean. Running power head now too. Is it ready to use or should I cure it.
Live sand was in saltwater, had no flow or heater all summer. How can I use this or is it bad.....I thought maybe put in new saltwater in bucket with skimmer and change water. Any tips. Thank you.

i'd toss the sand and keep the rock. if it's completely dry and has been so for a long time(how long is a long time?), it should be ok to add to the tank.

Thanks Mr.X Im not sure how long for 5 months maybe. Its real dry pure white. So rinse like I did and then put in? The water in the 20g container slight yellow now.
Im removing the crushed coral and use just sand later. Is it better if I put the rock on glass then add sand later when I buy some. I heard some put the rock on the glass so it wont fall, is that safe or will it crack the glass? I have some under gravel filter from old tank could put that under live rock. Will that work or?
Its a 55g all glass tank.

it won't crack the glass unless you drop it in.
the water is yellow due to all the dried up dead stuff that was all over it. just to be safe, put it in a bin with some salt water with a heater and powerhead and test the water for ammonia and nitrite for about a week.
better safe than sorry.

I changed the water and now it looks real clear. I will test the water to be sure. I will be sure not to drop the rocks I try to be carefull.
Thanks.
