Is this rock safe?

[Bent17]

Hi all, I needed some small rocks for my Zoas and my LFS had rock with dead coral used for zoas which looked ideal and no need for me to stay hammering down rocks.. My concern is:

Is it safe for my take (will clean with TDS 0 water)
Will remove old coral / putty
Could I crash my tank in any way

I'd use it.

Would you add some hydrogen peroxide when cleaning the rock or no need? And would you put in sump for a few days before?

I usually bleach the rocks (pretty much kill everything), rinse, sun dry for 3 days, soak in RODI water for a day, and put inside the tank — absolutely no issues.

Pour water into bucket, add bleach (unscented) solution, add rock. 1:10 bleach:water is good enough.

Ok, vinegar should work as well

Ok better go out and buy. All I have is Hydrogen Peroxide

For such a small rock, it should be fine to use hydrogen peroxide to sanitize the rock, although I have not personally tried it. I’ve always used bleach and/or vinegar.

I just put the rock in a jug and put some 3% hydrogen peroxide and leave it soak for a bit .
