How to Bleach Dry Rock from previous tank owner

[Reefrock]

Hello..

I am setting up a new tank using what was Live Rock obtained from another tank. It has sat dry in a storage bin for 2 months, so I need to cure it with bleach prior to cycling, etc. It seems solution is 10:1 ratio but time needed in the bleach solution has varying thoughts. I am looking for opinions/reccomendations on how to bleach the now Dry Rock.

Any help is much appreciated.
Thanks!

When I’ve done this I let it sit in the bleach water with an old pump circulating the water for about a week. After that I’d change out the water with new RO water every other day for as long as it took for me to not smell bleach anymore and then a couple more changes. Circulation pump running the entire time. Never had any problems with pests or bleach in the tank using this method.
