Tank upgrade

[Ifreitas14]

hi guys I’m setting up a new tank and need advise! I’m going from a 30 gallon to a 90 gallon and will be adding more rock to the new system so when I setup the new tank should I add the new rock and let it cycle or should I add the new rock and old rock that I have in my system now with the coral and fish and just put it in altogether at the same time?

If you already have the new rock, I'd let it at least soak in some saltwater prior to the upgrade, depending on how much you add will dictate how small or large a cycle will take place.
