What's wrong with this acro?

Here's a pic before

And today when I woke up. Have you seen this before?

It looks like a polyp is losing its zoox. I did some dosing last night of alk cal and mag like I always do and topped off water before. For what it's worth, my red digitatas polyps aren't extending the way they were but I took it out to get some algae off the base and reglued it back but this acro hasn't been touched. My green digi is doing amazing and so is my sunset monti.

Here's all three together

Sal 1.026
Cal 375
Alk 8.4
Mag 1250
Po4 0
No3 5

your calcium seems a little low, I personally wouldn't let mine get below 400 especially with an alk level in the 8's.

Ok thanks. I dosed last night and will test today again for calcium. Do you think this can continue? It looks like one or two polyps only and I've seen a little growth since I've placed them in the tank a few weeks ago.

just keep an eye on it, do you have snails or crabs. one may have just hit it a little before you looked at the tank? Another thing I would do is check out the PE at night, a lot of people say that's the best time to see how healthy an SPS is.

I do have snails and crabs. It almost looks like my zoas when they expell zoox. It doesn't look like tissue necrosis like I had before. Kinda looks like it's pooping. I'll check the PE tonight when I get home. Thanks for your help
