I heard about the zeo stuff and followed up on some reviews on RC. Apparently it doesn't kill them, it just "makes the coral stronger" so that it can deal with it. It's very expensive and should be used full time. Minimum 3 months for any real effect.
Everybody has to understand these types of things and that it's avoidable by practicing good bio-security. Dip your corals, or you WILL introduce something bad to your tank. It's just a matter of when.
OP, for your situation, if you can remove your acros, do so and dip them. Cut the plugs off frags and toss them. Use a toothbrush to clean the bases of your corals. It's a long and tedious job to get rid of these.
Even under a microscope, AEFWs are tough to see unless they move. You will not see them on a frag with your eyes.
