Bigsink,
I am sad to hear that, but I'm glad that you found the pest (problem). It Is not a chemistry or a physics problem (i.e. groundprobe) - as you now know.
Fact is AEFW don't impact Super man Montis and other types of corals you mentioned paling out/not doing well. Now that you know your tank is NOT pest free (Let's face it, none are), you should accept that you have several pests present and plan accordingly. I reccomend you begin making plans for a treatment QT system.
The good news is that although it may take a while to put together a QT system, in the interim, blasting weekly and weekly removing several corals and dipping them is working for me. (I remove either the worst looking ones or those not recently dipped.) Some corals came back quickly, and overall the whole systenm is improving in coloration as a whole. The dipping is working - its just not much fun.
You can go on this way for quite a while, perhaps indefineitely if you don't mind the work. So plan the on the QT system, keep your corals, and care for them, just like you would for a sick dog or cat, etc.
Bottom line is beating SPS pests is easier than beating hair algae, you just have to get in there and do it.
