OK, I'm kinda proud of this one... About 2 months ago, I got 4-5 little stems of this stuff which were half covered in BGA from my lfs's display tank. Now I have it taking over the front left corner of my 29 gal and it's time to do a little pruning. Is it OK to just cut this down like a haircut? If so, how often can I do this before I need to pull out the bottom and re-plant the tops?

Thanks in advance!
