Did you start with dry rock? That almost seems impossible.
Tech M's current formula did nothing for me in the past. Give it a try, but don't hold your breath.
Fluconazole is awesome, but after having used it multiple times, I can say that it will NOT 100% rid your system of bryopsis. But it does seem to condition the rock in a way that the bryopsis doesn't come back on existing rock.
I had treated with fluco and my bryopsis was visibly gone. I didn't see any for many months. Then a few heads of a torch died when my return pump seized. In a couple weeks, the dead heads were sprouting feathers. I chopped them off and haven't seen any since. So it seems bryopsis spores of some sort still exist in the system, but they don't start to grow unless they find a new clean place to root.
If your system is new, I'd move everything to a QT for the fish and then reboot the rocks. I'd kill it all by taking the rocks out and dunking in h202 or drying them.
Good luck.
