Monzer's tank restart

[SupraSaltyReefer]

Found my powder blue dead this morning. I don't see any scars/wounds. I'm just speechless.

Sounds like internal parasites to me. I had it happen in my frag tank a few years back. Every fish slowly lost their appetite and died. Dead fish everyday until they are all gone. How was the PBT appetite before it died? Was it eating nori aggressively. Like tearing it off the clip? How are the other tang’s appetite?

Apatite was decent. No, not tearing the nori off, but it was getting some and forging around. Same with the other tangs.

Your running a skimmer so doesn’t sound like low oxygen! .. Have you been rearranging any scape kicking up stuff thats deep in the sand bed.. Old undisturbed sand beds can release hydrogen sulfide but you would probably smell it or see numerous black/ red gunk pockets along the bottom of glass…
How much GFO ? And how much Gac were in the ractor? and was it rinsed real good before putting it in?
Since the whole reactor emptied into the tank Im wondering if the fish consumed some of the media? Like did you see any GFO & GAC floating around on the sand bed or sump? Hard to tell from the pics if their on the pinched side..
I have heard in the past that this could cause blockages in fishes gut depending how much they consumed…Doubt your new nems had killer sting..
Can call a local Vet who can send the fish to a lab for necropsy some want the fish in formalin which most vets have since they send in samples daily to labs or use local university labs some have their own requirements..Several years back a friend sent in a few of his koi to UC Davis Aquatic Animal Health Service Department which turned out his fish had KHV ( koi herpesvirus!) I was glad to know only koi get it since I was knee deep in his pond!! He lost 17 outa 20.. Wasn’t that expensive but he got piece of mind.. Sometimes you never know even after necropsies on animals which Ive had numerous done from breeding exotics back in the cowboy days of Miami…
Just tossing some thoughts out there tried to stay outa the rabbit hole!!
Sorry for the fish losses!! Sucks
Hopefully you will figure this out..
Best!!

That PBT looks really terrible to me - was it dead for a few days when you found it or did it look like that at time of death?

If the remaining fish are eating…
Are they pooping?
If so, what’s it look like?
