recovering bleached acros (pest damage?)

[ajm83]

I bought a lovely pink millie and two other acros a few months back. Recently my doser malfunctioned dropping alk slightly (8 to 7) and the milli STN'd, this gave me cause to look at these two with the tank lights off, they were looking pale but I didn't realise how bad they really looked until I looked at them with a torch last night.

Could I please get some advice on the best course of action to save them? I cut the light power from 80% to 50% in case it's just too much light (80% was PAR of around 350 uMol).

The white patches are concerning me though that it could be flatworm damage. It could be just the skeleton showing through the very thin flesh.
Unfortunately they are encrusted to the rock so I cannot easily dip them or examine with a microscope without scraping them off.

When I had a major bleaching event(everything in my tank bleached but did not loose flesh), I actually did nothing! Never did figure out why or what caused it.

Well not nothing, I did do a WC and aggressively run carbon(changed every 2 days to get whatever contaminated my water out). But did nothing else. I run a non dimmable T5 setup so no way to turn my lights down.

Within 2 weeks everything started to recover, and now 2 months later everything is colored back up and growing very nicely.

Sorry not much help, but it's what I experienced.

Thanks man, good just to be reminded not to panic and take things slowly to be honest.

I guess the thing i'm most worried about is that it might be AEFW. Does anybody have any comment on the white marks?

The aiptasia could be another reason as well if it dies off.

Ah, that's actually a barnacle I think! Cool little thing actually. It sticks that fan out and waves it around like a radar dish!
