Best way to trim Bolbitis

Well I've got 2 13w cfl on my 10g. The leaves right under the lights have some GSA. I do have parts that are slightly transparent like yours, but no color change. One piece has thick broad fronds, while the other piece has tight curly fronds. :huh:
 
I can only image what the rhizome looks like. lol

This looks like it will be my weekend project. Between this and the java moss...this tank is amazingingly stuffed!
