feather dusters?

[ccg24]

One of my Feather dusters didn't make it! He left his tube this morning and I was wondering if leaving tube in the tank was ok or not?

Its not gonna serve any purpose to leave it in the tank, so I always take any abandoned tubes out. In due time though they will rot away, but if it adds to a biio load or not I could not say.
