    In my area it seems the only live rocl we can get is INFESTED with either bristle worms or gorilla crabs, and a few things we have called "twitch" that look like a type of mantis shrimp. I was wondering if there was a way to get rid of these things safely in the future without damaging other livestock/coral on the rock...how much damage will freshwater do? what about something called coral rx? I have heard about pantyhose/knee highs for bristle worms...we tried that, should we use fish net hose so they actually get stuck? lol. I like supporting my lfs and their product...just not the hitch hikers lol. ;)

    I have never tried this, but you should be able to dip the rocks in hypersalinity water (I forgot how high you need to go, but around 1.035?). This will cause inverts to scurry out of the rocks.

    Again, I have never tried this, just what I have heard others do.

    As mentioned, a 10 min hypo bath is a good start, SG for this hypo should be 1.041. Sit the LR in a bucket with the hypo water, wait 10 mins, remove the rock, and sift thru the critters in the bucket, discarding the baddies, and saving the "keepers".

    What kind of reaction will hyper salinity cause to soft corals ? Can they go into shock and die ?

    What about a fish that would eat them but not terrorize my tank?

    Bristle worms are a good thing.
