Is this the start of RTN/STN

[Reef man 89]

Is this the start of STN or RTN? Start to show up like 5 days ago and now there are white strings coming off coral. My water is
1.025
78/79 temp
Po4 0.05
No3 10 ppm
Cal 410
ALk 8.0-8.5
Mag 1300
Ph 8.2 -8.4

dose BRS 2 part and acropower daily.
Base of coral right side you can see the tissue lost

You sure it's not growth? Sometimes growth looks discolored and jelly like.I hope it's that. Good luck

It’s definitely encrusting the plug but when I started to notice tissue lose and the white stings coming off I got concerned.

Anything changed in the tank? Parameters, lighting? Are other acres okay? Ask yourself all those and more. I saw a slight decrease in polyp extension and I said, somethings wrong. Guess what? I had reset my BubbleMagus to increase the two part and didn't exit. The thing stopped dosing for a week! My ALK dropped to 6.3. I started it up SLOWLY and the ALK is rising day by day.
Just an example of silly things that can have ill effect on our pets.

I did go over everything. Checked my Neptune dos to make sure everything was dosing properly. Check my temp with a Hanna. Compared all my trident parameters with Red Sea and Hanna checkers and they all with in there Accuracy window.the only thing I did was different dose vibrant 2 ml 2 weeks ago to try to help with bubble allergy. I do have a icp test be delivered tomorrow. All my other sps look great it’s just this one. Hopefully I am just over thinking it and it’s fine.

Go easy on the Vibrant with acropora. There are many anecdotes of negative impacts. No data, but lots of stories.

Keep an eye on nutrients if you keep dosing.

I am hardly an expert, but if this is what you're talking about, it looks like a mesenterial filament to me

Is this a Foxflame by chance?

Mine has the same look too it on the edges of the base where it is encrusting.

I've seen mine do that a lot when they're basing out. Might be mesenterial filaments clearing the way for new growth.
