bubble deflation

a couple of days ago one of my two bubble corals just deflated until all
that was left was a white skim on a piece of rock. there were no water
quality issues that I can pinpoint other than the removal of about 24 sea
slugs that may have been plundering my corals.
now today it's pal has done likewise but after a few hours it has returned a
little to almost half it's original size. I can see a few very small
bubbles on the other piece and I'm wondering what would cause them to go
downhill so rapidly, one day great and within a few hours totally deflated.
the only thing I can see is a spike in the nitrates to 10ppm but that would
hardly cause this would it?
my xenia are all closed up to so have I released something into the water as
I captured the slugs (with tweezers) but the mushrooms etc... are fine and
larger then ever with the button polyps popping up all over the place.

You better start running some carbon immediately. If these corals continue to
decline and even die, they'll release their own toxins and it could lead to
further deaths.

Clean up the water now, and hopefully everything will recover. Run the carbon
actively through a HOB or Canister filter, rather than passively by tossing a
bag full in the sump.
