Sorry to hear that, I had them a couple years ago and it was awful. I dipped every 48 hours for 2 weeks where I could but they continued to thrive on the encrusted montis. I sucked them out with a turkey baster at night until I realized they were winning. I then watched them eat all my montis (except my seotsa that they never touched) over the next few months. I didn't add a new monti for 9 months(probably excessive.) I do keep a yellow coris wrasse and springeri damsel in the tank now as a preventative measure just in case I get them again. I can't say yet if they work though. I have a frag of your tubbs that i will just let grow in my frag tank for you until you are ready to try again.
