SPS ISSUES :(

Can u get some pics meowzer?

Could be slow tissue necrosis. Its commonly called STN and its where the tissue kinda degenerates in my belief.....im by no means an SPS expert though so id do some resrearch myself if i was u!

Wats ur alkalinity or DKH?   Sry i have no idea how to fix this. Im going off wat ive seen and read on other forums!

idk lol

u didnt test it before the w/c??? thats wat i would have done...you could prob test it in an hour or so! This is the big tank right? It should all dillute and mix quickly

lol i think it made us both happy....

I have had this happen to a green birdsnest out of nowhere too in my 75, and it spread to my blue acro. My advice is to frag it now before you loose it all. Make sure the fragged piece doesnt have any white areas. Large water changes did not help me, and if I had not fragged it when I did, I would not have it now.  

I got some SPS frags from king neptune and he told me to do the same thing! He said you could cut the white off but not to worry...as it was just bleached out! However it still is white and no polyps or new growth on the white area from wat i can tell!

First get out your magnifying glass and check for tiny red dots where the flesh meets the white skeleton. Do you notice any swings in your alkalinity? Not enough flow can cause tissue recession from the base up.

One of the most prominent issues for bleaching from the bottom up is shading. Your colony grows so thick that light does not penetrate to the bottom of the colony. This does not look to be the case here.

Another issue would be phosphate leaching from the rocks. Heavy feeding, not enough flow, not enough skimming, not blowing the rock work of accumulated detritus can all add up to phosphate on the rocks.

Just some things to think on.

Heavy feeding depending on your mechanical and biofiltering acapcity can leave uneaten food and yes this could lead to a buildup of phosphate that would wick into the rock from the sand bed and from the rock harm the coral. I woudl keep a good eye on them for the next week. In the meantime I would take a branch or two from each and secure them in another area to ensure the survival of the species. Remember when fragging, if you do, to cut a brand above the white and into the fleshy part.

Everything else looks good Lois. On the last two pictures you can see the effect of shading on the elkhorn and the monti where it is white under the parts that shade the other parts.
