I think I got it mostly untangled Rock but that was something I considered carefully. I have two 10 inch airstones directly under the mass and I loosened things up a pretty fair amount I felt.......I could literally feel air bubbles coming up through the root mass after untangling for awhile and while I did lose some smaller roots I really don't feel I lost anything major rootwise and really think I got everything loosened up, flushed through with some H202 water and improved circulation to everything by about 50-60%. I spent quite a while at it.

Tip: Untangling the roots was much easier and less damaging overall when done while the roots were underwater and floating around......and the airstones helped as well.
