Thanks Kien!
I spent about 5 hours on it last week. It was my pennance for such neglect!
a lot of it I could just scoop out with a net it wasn't even attached to the rocks. There is still a lot left to pluck off the rocks but that Angel is really making a difference. It will be awhile before I do anything with the tank other than recovery.
I might start a "nano" tank for my room until My main is fully functioning again. otherwise I wont be able to stay patient lol.
