Prsnlty, your aquarium is quite impressive. If you could set it up on a live feed I could break my tank down and use the space to stack old magazines.
On a serious note, I'm just over 4 days in and most all of it is white. Low flow areas are matted, and higher flow areas are wilting. It's pretty exciting. The dead red wire algea was eaten by my emerald crab. I am closely watching a large section attached to the glass. It has all turned white, except for the root/base where it is attached to the glass. If that dies, I'll have more confidence in it killing roots that are embedded into sand and more importantly live rock.
