When you say formalin, you are including ruby reef rally, correct?Methylene Blue is an excellent first bath, especially for fish that may have been exposed to ammonia during shipping. NFG is also a good choice, both are quite gentle and can only help, IMO. Formalin and FW dips, on the other hand, I think can be overly stressful and damaging to a new fish, and shouldn’t be used as a first line of defense unless absolutely necessary. But that’s just my opinion.![]()

I'd do MB and then peroxide right after, unless the fish looked like it wasn't going to survive a second bath. They're both pretty gentle baths, IMO - if a fish doesn't survive those back to back, it's probably unlikely that they were in very good shape to begin with.Jessica, if you felt it necessary to do both peroxide and methylene blue would you do them one right after the other (presumably the methylene blue first), or wait in between? TIA

100% agree. If the fish can't make it through a fresh water dip or bath using methylene blue (and the two are different) then in most cases they won't make it through other treatments. I say this only from my experience and success rate of using methylene blue dips and baths following Fenner's recommendations. It doesn't mean that a few here with more in-depth procedures and systems can't move the needle to a higher rate just that I have not been able to or what I have experienced.
I also can't say what sort of success one has when not doing them but the other QT practices deployed here. So there is also that. I just am really biased towards the freshwater methylene blue for my livestock.
I know Fenner used methylene blue but have been unable to find the info. Do you have a link by any chance?
Rally is a fine option for multiple scenarios:Now, in the context of the overall page he may be recommending this with a known-sick fish... that's a little unclear. Maybe @Humblefish can clarify for us?
thanks much!!
IME; Rally is far more effective as a 90 minute bath treatment than dosing in a QT. But if you're dealing with Uronema, a formalin bath is the better option:what about RRR bath in established qt tank? looks like uronema snuck past first 90 minute bath so i know fish need another bath and transfer to sterile tank. but can i run the bath in the established qt i already have, i can remove filter, biomedia and rocks. just wondering if established bacteria in tank will break RRR down faster than just setting up fresh tank. any thought?
