Am I going to kill this Bryopsis ?

I agree with this, if you do, you have to grab each branch with your fingers and make sure you don't let go. Even when i did this, i would see it reappear in new places about a week later

 

I removed all my rock and bleached it and I am starting over I am not gonna just put band aids on and hope it will die and maybe not come back I have done all I could I added a better skimmer a few months back, I added a phosphate reactor, I added a bigger sump with a refugium ,I barely feed ,I changed my lamps I added a huge clean up crew the Bryopsis was the only algae there and it was kickin my ass. I nuked the rock I am gonna start over I didn't like the layout anyway I am just pissed off about spending all that cash on nice LR to just have to bleach it out a few years later I even tossed a few corals that the Bryopsis was infecting I think this officially is called taking it to the next level. Thanks for the input guys.
