Just letting the mind walk ... if the infectivity of Vibrio vulnificus is iron dependent, and if this microorganism plays an important role in coral diseases, as a very present part of the microbial complex involved, perhaps the concentration of iron in our aquariums has an importance higher than previously predicted and perhaps its induced limitation with the use of chelators, if necessary, may represent a pathway to be followed for the control of these diseases, especially STN.
There is a specific chelator for iron (which is also capable of binding to aluminum), which has been developed for use in human medicine, but has also been used in testing and is known to be safe for corals (but not for zooxanthellae). whose study for use in aquaria may perhaps be developed. This chelator is desferrioxamine B (Desferal® Vials, 500mg or 2g - Novartis Lab) and appears to be very effective.
However, there is a limit that should not be exceeded in iron depletion because it is also a very important element for the proper functioning of zooxanthella photosystems and when their concentration is below or above optimal levels, also depending on temperature and of the intensity of illumination to which the coral is submitted, oxidative stress bleaching may occur, as read in the article below:
