Thanks for this thread, after ten years of fighting bryopsis in my 2000 liter system, I am extremely excited to see if finally I could get rid of this curse.
I went to a local wholesale medical and agricultural supplier, and he gave me a bottle that says on it enilconazole 15%, when I told him that what I need is fluconazole he told me that it is the same exact thing, but this is for agricultural use and it would work the same in my tank, I am not relying on this at all, and would not experiment on my tank without confirming 100% that this is true.
So if anyone has any knowledge on this, I would highly appreciate your input.
