You're welcome FishPharm.
This medium (of writing notes -- posting) doesn't easily convey the 'tone' or 'intent' of the written words. I often write abruptly, but I mean to be helpful and informative without being offensive. So I am very glad you have not read into my writings anything derogatory, condemning or judgmental on yourself.

The Maracyn products are my favs, but they aren't the only ones. Do you already have other antibiotics?
Here's some info on Maracyn for you:
One of the best meds is Maracyn Two for Saltwater fish. That contains the antibiotic, Minocycline, along with B complex vitamins to improve appetite. This antibiotic is absorbed through the fish's skin and will help it with internal infections. For a slightly more hard hitting punch when the bacteria may be Gram Negative, is to use both Maracyn Two and Maracyn One, together.
It is preferred to use these Maracyn products for Saltwater Fishes. That formula contains B complex vitamins to stimulate appetite of the fish. However, you can achieve success using just Maracyn Two and/or Maracyn One for freshwater fishes, in your saltwater QT.
A good article on antibiotics:

Maracyn contains Erythromycin, Maracyn Two contains Minocycline. Two very different meds for different bacteria. One antibiotic attacks gram positive bacteria and the other, gram negative. Knowing the type of bacteria you are battling comes in handy when choosing one over the other. If you donââ"šÂ¬Ã¢"žÂ¢t know the kind of bacteria you are dealing with, then you need to go by the fact that most bacterial infections in marine fish are GRAM NEGATIVE bacteria. Thus, Maracyn Two for Saltwater fishes would be the medication of choice. The great thing about this medication is that it will work even when your fish will not eat. It penetrates into the fish and even helps the fish overcome internal bacterial infections (like those that cause eye swelling and/or Popeye conditions). Also, it has no adverse affect on your bio-filter activity. It leaves those bacteria alone.
Maracyn One for Saltwater fish is an antibiotic that attacks GRAM POSITIVE bacteria. This medication will have a distinct negative impact on the biological filter (as do most GRAM POSITIVE antibiotics). Itââ"šÂ¬Ã¢"žÂ¢s a
must to only use this medication in a QT.
While Mardel does not promote the use of any of these meds in a reef aquarium, Maracyn Two has been reported to be successfully used in a reef. I have used Maracyn Two for Saltwater fishes in a FOWLR aquarium on several occasions without adverse affects. However, Mardel (and I) recommend you only use these products in a quarantine tank. Also, Mardel claims their Maracyn can be used while using their CopperSafe treatment.
