Weeping willow rotting??

[beardedman11]

Just notice my weeping willow seems to be rotting or something in one of the folds. Powerhead got turned off for a week before I realized so didn’t have a ton of flow but turned it back on and saw this. Should I take it out and dip with some iodine or something to help it? What’s best? Or frag it out into a bunch of pieces and Toss out that bad part/area.

Doesnt look like rotting yet. Anyone eating it, i would dip to see if anything comes out and than do a lugols dip. If it continues to deteriorate i would frag, these things are super hardy
