Curing live rock and cycling new tank

[stevediaz1]

I have a question I'm curing my live rock and my heater was on the on position when I got home from work water was at well over 99 degrees did I kill everything? So what I did was replaced all the water with fresh salt water and I'm starting again did do right or wrong please advise I'm trying to cure the live rock before I cycle my tank I'm doing this in a container not my tank that's my understanding from watching all the videos on YouTube on curing live rocks before the actual cycle the reason I'm doing this is because they say the die off is there and this will help remove it or is this the same as cycling the rocks in my tank sure seems to me they're the same am I right or wrong please advise ohh and also

oh i have a question i noticed that also a couple of rocks are changing color to a greenish color and the purple is looking kinda weird in a few spots why what does that mean here is some pics and did i kill the coralline algae with the temperature rising to a high temperature it rose to about over 100 degrees for about a day maybe 8-10 hours here some pics

Personally I would not cure live rock for a new tank if the tank was established then yes curing the Rock is a must but in new tanks you really don't need to worry about curing them in a different container. As for the color change yes it's possible some of the coralline died off don't worry coralline grows like crazy in well keeped tanks good luck.
