It looks nice, how much you want for it haha jk. Though I agree with carey, you should put it in the tank to help the cycle.
I did rinse it pretty good. Can I use tap for the initial ronde and finalize with RO?
Yes. Your "cured" rock will still have die off and you can place it in an already cycling tank.
Before. Yuk!
