Something bad is happening

[EDJFA]

This started when I was on vacation. At least that's when I noticed theses changes.

To recap - I went on vacation. There was a storm here that reset my lights memory. My office assistant got them turned back on, but left them on 100% both channels all week, day and night.

I had the lights maxed at about 80% on the blue and maybe 25% white/other channel.

Now, weeks later, my coral still isn't looking good. Here's a couple examples

I've reset the lights to my normal schedule. I've tested my water. I was low on Calcium and Mag, but nothing different than before I left when things were fine. No nitrates or phosphates. I had Steve at Corals n more double check my findings. He said I needed just a little buffer.

This is driving me crazy. I don't even know where to start to diagnose the problem.

Am I blaming the light issue, but really I should be looking elsewhere?

Sorry for the crappy iPhone pics. I really just wanted to get this post up. I noticed the tissue recession on that second pic today. I'm not even sure what it's called. It's normally inflated 3X that size. It's even added a coupe new heads over the last couple months. It was finally starting to do something after a long time of just being one head.

My guess is they're starving right now with you having zero nitrates and phosphates. While on vacation you cooked all of the zooxanthellae out of the coral. It will take quite some time to get them back into shape.

That makes sense.

Is anyone here feeding their tank anything specifically to raise nitrates? As with anything on this whole forum, when you search for something like "nitrate dosing" you get a ton of threads with a bunch of people trying this or that. Lots of opinions not a lot of clear direction.

The after effects of coral stress can last for weeks due to their slow metabolism. Take your time, keep params in check and don't do anything drastic. Feeding the LPS small meaty foods once or twice a week will help to boost recovery and will add some nutrients to the tank for the other corals.
