So I thought these fruit packages would be a good powerhead protectors, but I'm wondering if the material (styrofoam) will degrade or be an issue in the tank? Thoughts?

It sure is handy to have a proper chemist informing discussions like this!Pure "styrofoam" is polystyrene, which will not biodegrade in any reasonable time.
If exposed to bright light, especially UV, it can break down to powdery bits over time.
That said, i do not know if they put other ingredients into it.
I know huh! This forum is so great, Thanks @Randy Holmes-Farley !It sure is handy to have a proper chemist informing discussions like this!
