Bleaching rock or using vinegar

[byee]

I used a 50% vinegar solution to 'bleach' my dried liverock for 6 weeks with a power circulating the water. Followed by a water for another 6 weeks changing it frequently.

I also hosed down the rock using a high pressure hose during the process.

I used vinegar instead of bleach based on comments from various forums - easier and safer.

Aquascaped my tank using my 'bleached' rock.

A few months later, I noticed a light color substance growing on the rock. It was caused by the dead organic substance leaching out of the rock.

Rather than dealing with it, I decided to remove everything out of my 45g and start over. Instead of liverock, I used reef rock for my aquascaping to avoid surprises.

I highly recommend just buying reef rock instead.
