I'm thinking Bryopsis as well. I'd hit it with Flucon just to be safe.
I’d also hit it with Fluconazole. It’s the only thing that worked for me
I ordered some Fluconazole and it will be here tomorrow. I really didn't want to resort to this right after the cycle but if Bryopsis, then it is taking over quickly. I guess that's a good sign that the lights are working.....or that they are algae magnets.
Probably a good idea not to add the macro algae for the next couple of weeks?
