no. that's not true. an iodine dip, can possibly help, but dosing iodine without testing for it is a bad idea. the brown jelly will not always be present. and i do not agree with the brown jelly being noticeable or something that you can look for before it happens. i believe that all info about it thus far is speculation.
btw, they list like 20 possible causes...they have no idea what the scoop is. they know about as much as you or i do now.
i do know that i have done many things to combat it, and then nothing but fragging the infected head off, and both had about the same results.
in the end, you want to separate the healthy tissue from the afflicted, ASAP.
it doesn't make any sense to run a UV
sterilizer part time. i'm an advocate for not running one at all. the only way it would work is if you had the entire tank under UV
light. we all know that can't happen.
it's a mistake to purchase another indo elegance. it will fail. just look online for an aussie one, or perhaps ask your LFS
to put one in the next aussie order. they do order aussie corals, right? it should be an easy task if they do.
