The nudis are a waste of time. Catch your wrasse and QT him for a while and drop some peppermint shrimp in there. Ones caught on the Texas coast are preferable, as I know these eat the nems. They will nuke your problem in a week. ORRR you can setup a 10gal tank with tank water from water changes and some LR. Put your infested rocks in there one at a time with a few peppermints and they will clean it. Then ad it back to your tank.
