I already went the drastic route, so here is hoping you don't have to. Keep the thread going man and thanks for all of the updates.I just ordered a bottle of VIBRANT - Reef aquarium cleaner. I saw a video on youtube of a guys tank filling with bryopsis like mine. He used this stuff for a few weeks and and it completely eliminated it, along with bubble, and GHA. If this doesnt work i have a bottle of 35% H2O2, and a complete tear down with have to happen.
