Toadstool not looking good

[blkhawk10]

i have a green polyp toadstool that has been looking less than healthy the past couple weeks and it looks like the flesh is coming off the edges...here's a pic I just took...what could be going on? I won't have any water parameters until tomorrow but I have multiple other lps and softies in the tank and this is the only one that looks bad.

Can you rule out shedding?

 

[blkhawk10]

Yea...it hasn't been fully open for a while now after looking beautiful for months.

 

[CodyRVA]

Well, apparently shedding is a natural reoccurring event. I have a toadstool about a foot across and I swear it's never shed. Has your chemistry changed or your flow? Mine tends to like low indirect flow.

 

[blkhawk10]

I'll have to check the chemistry tomorrow, the only thing that I can think of that changed was I set a bristle worm trap and had some lps food deteriorate for a couple days and then I put a shrimp in it and left that for a day. I've done two water changes since then.

 

[CodyRVA]

Gotcha, they tend to tolerate nutrients, so if your LPS are unaffected, I can't imagine it would affect your toadstool. Any chance of coral warfare; no sweeper tentacles or anything making contact?

 

[blkhawk10]

I haven't seen anything I've been checking multiple times tonight and all I've seen was a bristle worm on it and maybe a copepod.

 

[CodyRVA]

Do the polyps extend during the day? They seem to be pretty resilient; I stripped my system of nutrients in the past and it went bone white for weeks then colored back up when the nutrients returned.

 

[blkhawk10]

Not too much...a little more at night but nothing like it should be

 

[CodyRVA]

Lighting all the same?

 

[eliramos]

Check your levels I had this same issue I just posted about.
Are you dosing anything?

 

[eliramos]

This was my before

This is my now

Turns out I've been overdosing for months and not realizing it.
My whole tank has been affected but I had no idea why because my test kit was faulty.
My mag and cal were off the charts and I had no idea. So make sure you test! It is finally starting to make a comeback so I'm sure you're can too

 

[blkhawk10]

I don't dose anything to this tank, just water changes and feeding
I just tested the water and the results were normal
pH: 8.3
Nitrate: 0
Alk: 10.5
Calc: 415
Mag: 1230

Should I do some sort of fresh water or iodine dip?

What's your PO4 look like? ALK seems a tad high, MG a bit low; stability is key.
