I would never put liverock and treat with copper but for hyposalinity it is good if the liverock does not have any coral on it, like the type of liverock that we leave in a sump is good. It will kill all things in that liverock, like bristle worms, bristle stars, pods etc..but otherwise the bacterias and the biofilter survive very well and does the job at filtering the aquarium.
then once the hyposalinity treatement is over the liverock can be returned to the sump, very convenient way to set up a QT fast. I always keep some liverock available for this.

Also +1 on the seachem ammonia badge. Really convenient.
