I took my tank down 2 yrs ago and kept all the rock. I did not rinse it out instead, I let it dry out and then put it away. Recently, I purchase macro dry rock.

How would I go about curing the old rock and the new one?
Dump it all together in trash bin with saltwater, light and heater?
or
Keep separate and cure only old rock?,
or
Keep separate and cure both?

The last time I started a tank, I cured live rock in tank with sand - Not a good idea
Thanks,
Adriana
