Derek's 225g - Magnifica / SPS Reef

Major tank surgery performed today. Pulled out the big red digi and had to significantly trim back the pacman acro, mainly because I accidentally broke it off. I also got wacked by my mantis shrimp - twice! No broken bones or bruising, but it hurt a bit.

Here's the little asshole:

Removed about a 5gal bucket worth of coral from the tank today:

Pacman after accidental removal - had this thing in the tank since day 1 and it's always been happy, until the back started to die due to the red digi encroaching behind:

Took a bunch of photos with the lights raised.

Fantastic shots!
 
Been a while since I updated - have been super busy with work and traveling almost every week.

Unfortunately, having some major issues with the tank right now. Seeing random corals with what seems to be some kind of infection. It's not RTN or traditional STN, although it's turning into STN in some cases. In many cases PART of the coral starts to look bad and then it spreads. In some cases things are just kind of turning brown and grumpy before eventually giving up.

I can't really figure it out - things I've changed:

1. swapped in some non ATI T5 bulbs I got on sale. These are actinic bulbs with (apparently) a heavy UV spectrum. Given that only some corals are impacted, this doesn't feel like the problem but I swapped back to the old ATI bulbs just in case.
2. Used a box of old AF salt after many months of using IO. Have since swapped back to IO and performed some water changes.
3. Stopped/started vodka dosing. I can't imagine this made things that grumpy, as I've done this in the past, but it's worth noting I guess.

Here's an example of what I'm seeing:


Bottom left of the coral looks great, top right is clearly something going wrong. This will spread.

Same thing on the fox flame - you can see the grumpy infection starting on the right. Other parts of the coral look fine:

Here's a maleficent frag that was finally starting to branch, now it's browning out with burnt tip:

My oregon tort has some weird, bumpy flesh:

I suspect it's bacterial simply because I would be surprised if any minor changes in lighting or water chemistry are causing this. It very much has "infection" vibes to me the way it spreads around. Some rocks are impacted more than others - I lost every single coral on a specific rock, and it seemed to spread from there. Some parts of the tank are totally unaffected (so far...).

ICP results are all totally normal, have continued doing those monthly. Just going to try and ride things out and stay as stable as possible for now.
 
Has this happened before? I had a similar issue I couldn't figure out, I also assumed it was bacterial. Cipro helped. If I were to do it again, I'd take out all my bio bricks during treatment. Good to know even the Acro masters have issues. I always assumed your tank just never stops growing. Hope you figure it out, let us know what works.
