Torch Receding but Full Polyp Extension

[duncantse]

I have had these torches for about a couple months now and I have started to notice that most of them are receding from the base but the polyps are all out and healthy.

 

Trying to figure out what is wrong with them as I'm worried they will die on me soon. They are getting around 200 par in that area

 

37 gallon reef

Alk 8.5

Ca 425

Mg 1380

Sg 1.026

NO3 10

PO4 0.06

 

I have attached a video of my tank so you can kind of see how much flow they are getting

Have you been feeding them?

 

IDK, my first guess for stony corals is usually alkalinity swings.  Any chance of that?

Wow those torches look like angry frogspawn

No I haven't been feeding them directly 

 

I test alk weekly and its been pretty stable at around 8.5 dosing 2 part

Yea I took those pics when the lights were off with flash on so you can see the skeleton when it's all closed up

Have you checked for EEFW? The last pic looks like there are a couple on the base, unless those are partial asterinas.

Yup those are just asterinas 

 

So I just did a dip on the torch that was receding the most and found this in the water.

Can somebody give me an ID if these are EEFW or does it just look like the slime coating of the torch

Need a darker background for more contrast....hard to see.

I've never heard of EEFW, but those are definitely something.
