I’ve had this GSP for about a month or so now. It initially took a few days to open up and then it did open. after about a week or 2 it kind of fell over and I repositioned it with a little bit of glue and it was in place. Ever since then it has never opened up again. It’s been at least 2-3 weeks. I recently cleaned it with a soft brush as there was algae on it - I noticed it was still in tact. However, today I did the same and it almost looks like some of it scrubbed off or just melted away. Is it dead?
