Shutting down tank, but keeping LR. What to do?

[toytech]

I did the same thing when I moved , took all my rock and bleached it in 5 gallon pails , then soaked in water , then let it dry in the sun which breaks down the bleach . When I set up a tank a year latter I cured the rock in bins with some live rock , got some phosphate leaching but it cleared up in less than 2 months .
