its pretty normal for all that type of algae to look like garbage when it comes in, it all looks really white, give it a week, keep your cal and alk up to support it just like a coral live plants i cant say enough good things about russ from live-plants, stay away from reefcleaners, lareefs has some small portions but sometimes rare stuff. Mike from sea had a big chunk of this green macro that i think sells as sponge but is a macro and depending on the angle you look at it, it turns from green to metalic blue
I have some reds i need to trim and i also have some purple 'octeles' i cant remember the species name ready to trim out of my little mangrove tank, pm me or call to come get some
