In her case, pineconning isn't a symptom of something else, she has true dropsy. Dropsy is an internal bacterial infection. Medicines that kill bacteria and parasites are most effective at treating it. The reason it hasn't gone down is that the Jungle's Fungus Eliminator isn't affective against internal
infections, which is what she has. It is keeping it at bay, but probably won't kill it. Maracyn II will kill the bacteria causing dropsy, as will Jungle's medicated pellets. Jungle's pellets have some of the same ingredients as their fizz tabs but it is taken orally so it is effective against internal infections while most fizz tablets are not. You do not need Maracyn I since I have found that Erythromycin is not effective against dropsy.
I am concerned about the initial switch between the fungus treatment and Maracyn II since that will be stressful but I do think it is for the best... Good luck with her.
