If this was my fish, I would use a furan antibiotic such as API Furan 2, Bifuran, or Jungle Fungus Clear.
(You can keep using Epsom salt for the popeye if you want. (But I think he really needs an antibiotic too.))
(You can keep using API General Cure if you want. (But it treats fungal and parasitical problems, not bacterial.))
For bacterial infections, you want the temperature on the lower side. (About 76-77F.)
I can see in the second picture of those posted last night a small bit of what looks like fuzz hanging off his gill. If that is actually fuzz hanging off his gill then I totally agree it's columnaris. But, at the same time I can't tell if it's just a reflection. Please advise us Lena on whether that is actually there, or if it's a reflection.
If it is columnaris then I totally agree with LBF. You can get Jungle Fungus Clear at Wal-Mart.
I think he actually looks better in the 2nd group of pictures than in the first. If it is just Popeye, and he already had a bad reaction (at least you think he was worse after it. correct?) to Maracyn II I would stick with the General Cure. If it is Columnaris, then Furan 2 or Jungle Fungus Clear would be your best option.
