My thoughts exactly. Fish death from disease seems to be far more prevalent in the US than in Europe. A mass dying from disease Is an unlikely event in this part of the world, especially since a fish hasn’t been added in literal months lol. Seems to be a presumptuous and unlikely cause in this case.
I'm too invested and enjoy this hobby too much to quit.
Yeah sorry buddy but this is far from the truth. You cannot go around just spouting "skipping disease preps is the cause and case closed". It's obvious something else is up, but you're not too keen to help out.
Trying to jam everything you see into the some theoretically perfect evidence based differential diagnoses engine is not the most efficient way to find answers. You can’t shave off all other contexts to force the fit or wrap things in scientific sounding nomenclature to make it more valid (biosecurity assessment??).
When you say you added a sump from an old tank, was it yours initially, disease free? or an eBay “tank breakdown” jobby. I’m assuming it’s from an old tank of yours, including the bioballs.

So, you think the fish ate this decaying stuff which gave them a terminal case of diarrhoea or something? Brandon429 will be more likely to agree with that diagnosis than an ammonia related one, that’s for sureThought I'd chime in here. I had a similar issues
Mysterious deaths
Well I found the problem... For a recap I have a 1500 gallon + system made up of two large tanks. A 450G mixed reef upstairs and a 750G FOWLR in the basement. The sump, quarantine and frag tanks are also in the sump room. The 750 has one plank feeding pellets and the plank sits right on the...
My fish would have increased respirations prior to death and I found the my plank automatic feeder was full of saturated rotting food. The only a few fish survived including my purple tang. I also did massive water changes but I also removed all the rock, scrubbed and rinsed it. Removed and replaced the sand and refilled the system (1500 gallons). My fish were indeed quarantined and held in observation prior to adding. I'm sorry for your losses.
Just remember to add fish back slowly to allow you system time to adjust.
It was my old tank that I used before upgrading to my current tank. It was used several months.
The media was from the canister filter that I used on this same tank. The hasn't been used thoe in weeks, so the bacteria in the media might have died, plus I threw the media in the sump 5 days before I filled it. They smelled kind of like harborish, but I didn't think it was a problem. The sump started to get that smell and soon enough the display had the same smell, that was when I discovered dead fish. Now that I have done a water change on the display, the smell is gone. It was so dumb I know, and now I have learned.
I suspect a spike in temperature which will affect both Ph and oxygen.
Tap Water and vinegar, I was scared to use any other cleaning stuff I had. Danish tap doesn't contain chlorine or any other sustenance that is dangerous to fish.
The temp has been a bit high these few days, around 26c-26.7. Now it stays around 24.2C
You may be already doing this, if not do half buckets. I have bad shoulders and did full buckets for a long time then untill I figured out doing halves is so much easier. I've also used small pumps like maxi jets to empty pails when I'm really hurting.
