Hey Coach I know a lot of guys here have said I believe its Cutrine plus granular works well on Chara.
I too have a Chara issue to about 4 feet all around my pond. I have had my air going to 2 years now except in winter and it has not put a dent in the Chara issues I have. I have some GC like 3 or 4 that are taking care of my pond weed but the Chara is crazy! I also have heard you should not rake it as it will spread?? Not sure on that but I thought I read that out here somewhere? I am kind of torn myself. I do'nt really want to add more GC but I also don't really want to use chemicals either??? But my Chara gets so bad I can't even fish in the summer at times! Good luck and if you find out anything that works well PM me please!!!
