i have some gfo in a reactor with tank water thats been sitting there for months, i had it running only for a few days before taking it offline. Is it still good?

It probably can still remove phosphate but i would rinse it wellll before using it since I bet it smells really bad

If the smell is okay, it's likely safeto use, although it might be coated with enough bacteria to make it ineffective at removing phosphate.
