So all in all. We changed a lot. Cut vinegar to raise ph. Siphoned daily now. No uneaten food. None. Cut rock back so not to trap food. And make tank more sterile like conditions they were used to we took off our ozone also. Screw it. I run 310 320 orp without it. So I think it was the tank raised fish put into a reef system with extra fed with carbon source bacteria and trapped food non sterile conditions and maybe lower ph than these guys used to. Opened some windows and cut the vinegar. I wished I knew if it was for sure all or any of these or antibiotics that saved them. But this was thought process.
