Yes, photos show chemical burns but not as bad as I feared from your initial description. Hopefully it's doing better now? I only posted because you seem to dose a lot of medications. There simply hasn't been enough time for a colomnaris infection.
If you want a gentle no medication way to control your issues, look towards an over powered UV filter. Ick, Velvet, costia bacteria etc. Not saying you will have these diseases but the UV will give you peace of mind instead of constantly medication.
