What are the requirements for keeping liverock alive?

[FutureBoyGenius]

I just reaquascaped my 90 gallon and have some more liverock left over. I will use them in the near future or get store credit with them, but right now I have no room in my sump and I want to keep them out of my display.

They are in tubs of saltwater. The water is not heated, will that cause dieoff? Also, there is no circulation, will that cause dieoff? This is only temporary, so would an airpump work for circulation?

It is about 30lbs of liverock?

Thanks

put a powerhead in the tub and it should be fine few weeks

If you want to preserve life on the rock then the best way is to use a powerhead to circulate the water, a heater to maintain a reasonalble temp, use top-off water to maintain salinity.
