Derek's 225g - Magnifica / SPS Reef

I've checked all the basics - with two different methods for most of the big ones. No swings in parameters or anything out of normal ranges for my particular tank.

Corals have not all started suffering at once. Some corals are not impacted at all (so far). That's why I think it's some kind of infection. Certain corals in certain parts of the tank are hit pretty hard and others are totally unaffected, and look great. This is the case across SPS+LPS+Softies - examples of each with issues and each doing great.

Of the corals impacted - they are kind of presenting symptoms in different ways at different rates. Some are grumpy, some died off relatively quickly.

I don't think it's related to my tissue concerns, seems like a very different problem. It all started relatively quickly about a month ago.

I kind of suspect the box of AF salt because I did a round of big water changes about a month ago with this salt, and according to my journal that's around the time things started to turn. It's also when I swapped in the cheap non-ATI Actinic bulbs I got during the BF sale. I'd be surprised if this is a light issue but worth noting.

ONLY other thing I can think of - when I was working in the tank around this time, i irritated some zoas pretty badly. I actually saw them squirt out some black inky stuff - never seen that before. Possible they released some of that palytoxin and it did damage?

Anyway, have one more box of AF salt PIF if anyone interested :p

I think @boun11 said he’s out of salt.

Also. The corals that died. Were they the harder to keep one’s ? Is your digi polyps still open ? Are your colors washed out ?
 
I had similar issues years ago but never figured out the reason or cure. I've seen this condition referred to as neoplasia or tulip polyp syndrome. Unfortunately most of the acros affected didn't make it but I was able to save frags off of them where some grew back into colonies.

Here's one of them. What was a vivid rainbow delight

This is happening in my tank too, I'll post pictures in my journal.
 
One of the symptoms I noticed when I started loosing corals (not all at once btw) was that as the corals get weak from infection, the ones closer to the light STN first. They seem to hang on for dear life when they are at the bottom of the tank or shaded. Unfortunately I didn't realize this until way too late. Before I started treatment I reduced my lighting to 30-40%. Did my treatment and started seeing improvements. I then re-increased my lighting slowly. I'm now at 100% on my AI Radeons.
