I have them again. Easy to contain in the grow tanks since everything is removable. I've been using R/O straight from the 1/4" hose to combat them in the display tank. Just like Joe, but on a smaller scale. With the volume we have, the 5-10 gallons of RO straight into the system doesnt affect the salinity or temp enough to cause problems. My Anthias and wrasses like the babies not big egg layers. I suck those ones out with the turkey baster once they are stunned and floating in the water column.
That is a great method...that I don't want to do again! Since they seemed to be localized to those corals, Ima gonna try this.
