Stinky QT

Came home to check on the frags I have in my quarantine system. It's been up and running for 24 hours now (I don't keep it running 24/7 just when I have something to quarantine.

It's an 11.5g that I equipped with a powerhead and a small piece of live rock from my sump. It's running at 80 degrees and 1.025-1.026 salinity with a fresh batch of Coral Pro salt that I mixed with distilled water. I've got 4 acro frags plus a zoa that I picked up from the LFS yesterday.

Dipped everything in Revive before adding to the QT. Some of the acros started throwing off some mucus as soon as they went into the dip. I tried to blow it off but it kept coming back so I just put them into the QT and hoped for the best.

Today when I got home from work and went to check on them, everything was stinky. Kind of like the smell you get if you ever open a coral shipment that arrived a little late and the stuff inside is dying. Not quite that bad but the same smell.

I did a 5 gallon water change (as much water as I had on hand) and threw a power filter on the back with a makeshift carbon bag.

I've successfully quarantined Acropora and zoanthids before without this issue and I've never run carbon on a QT before. Anything else I can do to lessen my chances of losing the corals? Are they dying from the stress?
 
Update: This morning the tank smells much more neutral. I think the carbon is doing its job. The stressed corals must have been releasing toxins into the water. No visible tissue recession on the acros, although only one of the four frags has any visible polyp extension, but IME that's usually the case in quarantine systems. The zoa polyps are wide open. Will do another WC tonight.
