GSP dying

[Hornet]

That's odd. I've never seen gsp flake away. When's the last time you did a water change?

I've seen some things here and there on different forums but I haven't found a good source yet.
It's weird, the last pieces left are still opening up. Even some of the parts that had gotten loose before were open but had fallen off.

I usually do them every Sunday. I clean my filterfloss on Wednesday.
