Hey all, have you ever done a beach bath for your dead live rock to remove organics before putting it into a tank? Also, if I'm setting up a new system do I need to soak the dead live rock before putting it into the main tank to cycle?
I wouldn't bleach it, as most LR is pourous and tends to absorb liquids pretty well.
If you're setting up a new system, don't even worry about cleansing the rock. I'd do a good rinse in dechlorinated water, and add it to the tank. The dead organic material will serve as an ammonia source while the tank cycles.
If it's an established system, I'd leave it in a bucket of saltwater with an airstone or powerhead for a few weeks, while doing water changes every few days to remove organics from the water. Should make it safe to use in an established reef, without any chance of a large cycle.
