Hi hi, I talked to my medicator-- She told me she uses "salon select" brand peroxide, I think it's very high grade/potent.. Maybe a hair salon can give you some. She tells me that she puts 1cc for 20 gallons-- very strong stuff-- in a quarantine tank. She says that it softens the lymph, and to try to gently scrape some off on a daily basis, and to treat with mela/pima between lymph removal sessions, I think in another bucket, to promote growth and health. Don't try to peel off too much at a time, because it could cause serious trauma/injury to the fish. HTH
, it seems to work quite well on the angels we get at our holdings facility who have it really bad.
