Favia rapidly declining, death imminent - diagnosis?

I got this Favia and Anthelia as hitchickers on some LR (boy was I happy.. mostly for the Favia). It's been doing very well and slowly growing in my tank for the last 4 months up until early yesterday.

I first noticed the clove polyps were retracted and not looking so good. Later in the evening I noticed that one side of the Favia (closest to the cloves) had a white puffy mass covering one or two coralites... and some of the cloves were sloughed over and appeared to be melting. Today I awoke to more bad news... the cloves once strongly competing with the Favia were all looking very poor and more coralites had succombed to whatever this malady is. I siphoned off what I could. My other corals look fine... except a hydnophora frag that isn't as fully extended as usual.

Water quality is pretty good.. test with Salifert. Alk is a wee low but everything else is where it should be. Last WC was 8 days ago. I fed with Mysis shrimp the evening before this all began. The favia has always readily accepted Mysis, so I fed it as usual along with the other hungry beasts.

Now it seems the Favia "goo" is brownish in color. It's obviously dumping its guts.. or brown jelly, etc. You'll also see in one of the pics that the cloves are also exhibiting this brown stuff. Would really appreciate any help in finding out what this is and what could possibly be done. Have a feeling it's too late to save it but really want to make sure whatever's going on doesn't spread to anything else. Can provide more info/pics if needed. TIA

i would cut a chunk of the healthy are of the coral far from the browning/slimy part to at least save some of the favia.give it a lugols or one of the coral dips 4 or 5 min dip and put under low flow for a week or two and hope watch and wait.
 
Thanks for taking time to reply. It's gone... by the time I got home from work all but 2 coralites were left and they were on their way out.

Here's what I think happened. I've had a Hydor-Flo sticking off and on since last weekend. Seems to get stuck in the same place (gotta take it apart and clean). The direction it's in when it sticks puts the Favia/Anthelia rock directly downstream from the Hydro, about 8" away. Never seen the Hydro send out it's sweepers but it must have. I'm thinking that while the Hydor-Flo was stuck.. it carried the sweepers right into the path of the rock.
