Well unfortunately I have discovered that I am a victim of one of the worst pests you can battle. AEFW, Acropora Eating Flat Worms. I will say first off, I dipped every single coral I have ever put into my tank. But unfortunately all coral dips do nothing for AEFW eggs. I have used coral Rx for everything, until recently reading about using a insecticide made by Bayer. I have used this dip now for the last 6-8 months, and the results speak for themselves. I was lucky enough to have just upgraded my sump and skimmer on my DT, so I am using the old sump and skimmer on my new QT. The plan is to pull all Acros from the tank, desrtoy any encrustation on any rock, and put all the Acros in my QT for 8 weeks. Dipping once every 7 days. AEFW will starve and die in 5 days without any food source. The gestation period for the eggs is 2 weeks. So during the QT process all living/remaining flatworms will be eradicated from my DT due to starvation. I have already began dipping what acros I can, and have placed them on frag shelfs or racks until the QT was ready. Here is the dip I am using. This can be acquired at Lowes for about $12. I use 5-6ml per 1 cup of SW for 10 minutes. I put heavy flow on the coral, and also blast them with a baster at the end. Rinse in clean SW and place back into the tank. Warning: This dip is highly toxic to inverts. You will want to rinse each coral very well in clean SW after dipping, but this is no guarantee that it will not kill off your ornamental shrimps and some of your pod population. This is why I highly suggest using a QT. This is what the first dip results looked like. How many AEFW's can you count?!
