Hello all I am a newbie here, I have only had my tank up and running 4 months now,30 gallon with jaboa wave maker and hob filter, just introduced tank bred clowns male and female and 2 blue green chromis. about 30# live sand and 60#s live rock, went to the lfs the other day and picked up an already established piece of live rock and now I have eunicids and recently witnessed one of them kill my male clown. I was wondering if I dip my live rock if it would kill my coraline algae or if it would even kill these worms before they get out of control? I appreciate any insight on this problem. Thank you
