Does this look like mesenterial filaments?

[JCOLE]

I am currently dosing Vibrant and on the second month. I am stopping this week because 95% of my bubble algae is gone and I need to bring balance back to my system. I lost a frag in my frag tank yesterday to RTN and a couple of pieces in my DT look pale and have some receding flesh. I plan on doing a 30% water change tonight and hope it finds its balance soon.

I broadcast fed a mixture of Reef Roids, Benereef, and Reef Blizzard-S last night which I normally do about once a week or so. Shortly after feeding, I noticed most pieces appeared to have mesenterial filaments coming out of them. I did not see them a couple of hours later.

Do you think these are mesenterial filaments and if so do you think it is a positive or negative response? Sorry for the crappy phone pictures.

It does look like them.. They should be coming out of a corallite and the one picture does not though.

No they are usually not a good sign. It in most cases is a sign of aggression. Sometimes they do when feeding which is ok.

I rarely see it in sps.

That is what I thought. They do look like them though. Very weird that they are doing this. Can't see it as a defense mechanism because there are no other corals around them. Could have been a feeding response?

I will hold off feeding until my tank is stable again. I don't want to risk further stress during this time.

I had a Tort do this once. I placed a coral near him I had just got. A little later a few other in the same area started doing the same thing. I moved the coral away and it all stopped. I figured it was some type of coral allopathy.

I have seen a few sps corals do this when I added food before too.

Did this happen after feeding? Vibrant can lower nutrients. Is it a few sps or them all?

It was only a handful of them but more than usual.

I'm not sure what vibrant is, but I've seen this response in what seems to be an aggressive, damaging response at feeding time. I've noticed a higher likelihood of it happening when PO4 is too low or after big swings in alkalinity and/or PH. Low PO4 seems to most common IME and it seems to effect certain species more commonly.

Vibrant is a gift from God and also a curse from the Devil at the same time. It is the only thing that takes care of bubble algae for me. However, once done it always seems to throw my system off balance.

After a couple days I have noticed these a little more and it only seems to happen when I broadcast feed my tank with reef roids, benereef, etc.

When this first happened I tested my NO3 and PO4 and NO3 was around 25 and PO4 was around 0.06.

Vibrant doesnt kill any of my sps. Vibrant will lower your phosphates and nitrates if you're not careful.

If this is true, and there's a carbon source in there, I'd say low nutrients (N or P) are a very real possibility. When I struggled most with this I could practically tell when my nutrients were too low, as mesenterial filaments would be common at feeding time.

Yeah, I recently ran my phosphates down to .07ppm and some of my Acro's started getting mesenterial filaments. .15ppm it is then.
