You don't need to remove it immediately, if you want to keep it, treat it like any other substrate. If you see it go moldy which eventually it might then you get rid of it or if it gets dirty.

For my Corn, it's a moss box and I simply remove it afterwards cause I don't like the look of it in the tank. But for Python, the box never worked so I would just spread it in a section and mist, after shed I found no point in removing it and the contrast of it on the other substrate looked cool so I left.

Treat it like any other substrate and get rid of it when necessary.
