bleach used to clean, can liverock be salvaged?

[6Speed]

Hello. I just picked up a 65 gallon tank from my friend who wanted to get rid of it. It was sitting in his basement with about 100lbs of liverock and a 3" aragonite sandbed. It had a lot of algae growing in it, but no fish or anything...so he decided to put bleach in it to kill the algae. Well, this was months ago, and for a while now it's been sitting empty till I bought it from him. Is there any way I can salvage the liverock (now dead of course), and use it as base rock? How bout the Aragonite?

If so, how do I go about getting it ready to use in the tank?

Thanks!
Zack

I would think if you washed it and placed it in the sun a few days to dry it would be fine. The chlorine is probably already gone but what is left of it will evaporate in the sun.

I have used bleach to kill bad stuff on base rock. I let it set in the sun for 5-7 days before adding it to the tank though. If it smells like bleach after that, I just let it sit longer.

I thought I had read that the chlorine would soak up into the liverock and stay there for a long time? I'm glad to read that other people have been ok with the whole bleach thing...I was really scared I might not be able to use all that liverock. Now my only problem is buying enough liverock to stack up high in this tall tank.
