Help - Mushrooms dieing - sps/lps all fine

[chrissreef]

Help, I went on vacation for a week, I come back and my mushrooms keep dieing/sliming. I've lost probably $1k in various premium mushrooms.

Basically the pop off with filaments and brown slime from the foot and the mouth is gaping. I've tried iodine and sucking/brushing them off. Today I come home and 2 more are gone and I have 2 more looking like the attached image. Should I just flush them to avoid further losses??

None of these are wild, all from host tanks

ca 500
alk 7
mg 1250

Did 15% water change earlier this week and running chemipure. no improvement.

all sps/lps/ricordea are doing great, like nothing is wrong.

Oh my ya he is not looking good.
Was someone taking care of the tank while gone?
Maybe run lots of carbon for any toxins

 

[chrissreef]

yea, running chemipure. yea a trusted reef friend watched the tank -/

Is that your normal alk? A swing maybe?

Wish you the best of luck. I've been away 2 weeks now and hoping everything is good when I go home

Looks kind of like trying to defend itself. Are any corals near the mushrooms that may be stronger chemically? What else is in the tank? What snails and starfish are in there? I had a starfish decide to begin eating mushrooms once. However, it was a choc chip for my harlequin, so no big surprise.
