Set up seperate 70 frag tank plumbed to 60 gallon sump with slow flow into system. I have tried to set up a totally seperate system packed with monti colonies and frags when I had the monti nudibranch last year I killed 50% of my corals this way, as the alk, calcium , salinity, and temp were not stable.
Way I got rid on monti eaters was moving all montis to frag tank and checking every night for them buggers now montis are thriving once again.
This time I am not going to lose a 100 or more Acro colonies and frags. So with the slow flow to refugieum and then to main sump. 95% of my corals have never been infected. AEFW seem to only have minimumly hit bali tricolor, valida, and a few millis over 8 months
When I move at the end of the year I will either get a TL giant frag tank and put everything in there making sure parimeters are good, Or get a monster tank. Scraping all acros off and chipping encrusting stuff, Leave set up for 2months with no corals and then move corals over from frag tank. I dont know about the new rock method. I also like the ReefBum Melive method of using baster as I do not see any damage caused from AEFW after 8 month I have only basteda few times
