So I have had this favia for 3 months now. It used to look like this. But it has lost a majority of the blue around the mouths and is not mostly brown. There is still some blue left just very little. There is no tissue regression and looks healthy. I have it under PC with 3 ReefBrite 14 inch 50/50 strips built onto the PC housing. All parameter are where they need to be with the exception of calcium which is a little on the low side for me 300ppm. I run a custom built 30gal sump/fuge with coralife 55 skimmer. Main tank is 29 gallon. I put Fuel into my tank twice a week along with Oyster Feast once a week. I also target feet with cyclopeze and mysis every now and again. Coral is place mid tank about 12 inches from light in a medium high flow area. Thanks for any input you guys can give.
