I had a GHA problem last year after a snail died in the overflow. I tried every single remedy I could find with no luck. It would not go away. That bible mentioned above did not work for me. There are different strains of gha...definitely not a single bible for all strains. I tried all methods I could find except hydrogen peroxide and fluconazole. After 3.5 months, I gave in and tried hydrogen peroxide according to whatever was suggested at the time. Still didn’t work. Then I dosed fluconazole and it was mostly gone in 10 days and all gone in 2 weeks. No harm to corals or inverts including rbta and red serpent star.
I now have the problem arising again as I cannot find my male mandarin after I was out of town on vacation. I still can’t find him. If he didnt carpet surf, then I assume my current problem will need the same remedy...fluconazole. (And hopefully I can’t find his rotting carcass). I freaking hate GHA.
****there is also some really bad advice on this thread. Take it for what it’s worth. No one is correct for your problem because reef is different than theirs. Fluconazole worked for my strain of GHA. Nothing else helped.
