Please help!

Save my 5+yr old Christmas Favia! For the past 6 months I've had it center tank, on SB. No problems until last week. It has started to bleach on top and I'm heart broken. I cannot pin point the problem. I'm only running my whites at 11% max, Blues 50% max. Could this be to much/not enough light?
Today I finally moved it to the far right side, lesser light area. Is there anything else I can do to help it recover?

That doesn't look like bleaching to me. Bleaching is when the tissue loses color. There appears to be no tissue at all. My experience with LPS tissue recession/loss is a water quality issue. Remember the neon candycane issue a year or more ago? Try doing some extra water changes. And be sure to feed it. You should have a full recovery in time.

I feed Rods Complete frozen plus frozen baby brine shrimp 2-3x a day....small doses. WC every 10 days.
0 nitrates/ammonia. ALK 8.4, ca 440, mag 1400, po4 0.02, ph 8.2 and temp 79.9. What more is there?

It hasnt started betting hit by any direct or heavier flow has it?

[Sir Patrick]

Any salt creep land on it maybe?

Well for the last couple weeks my Royal Gramma has been digging out, then spits the sand on top of this one and the 2 frags. I've been using a turkey baster to blow the sand off em. I'm thinking maybe I did so to hard, or the baster has bacteria in it. Could also have been from flow...maybe. Definitely no salt creep.
The more I think about it, I honestly think I may have did it with the baster. Either way, I've moved it far from the Gramma's spitting zone. :)

Sounds like you figured it out. Sounds like a probable reason for this issue to me.

Looking at it during lights out, there definitely are sweepers coming out from the bleached out areas. So no tissue loss-good thing? I turned off all flow and very lightly target fed some Reef Roids. Which I said I wasn't gonna use anymore-ugh! But it's the only coral food I have.
Sometimes I sound like such a noob!

[Tom@HaslettMI]

A little off topic, but... Are you target feeding the individual coral polyps, or broadcast feeding the whole tank?

Tom

[MizTanks]

Broadcast. Just what I feed the fish 2-3x a day, very small amounts. See there's tissue, it's just bleached. I target fed it last night.
