3 days ago my Duncan closed and it was half opening and the other day my globulus urchin was right beside him (maybe the urchin climbed the Duncan I don't know) and it was carrying a piece of gsp that got stuck on his back. Yesterday it wasn't fully open too but I think it was in a better situation. My problem is that 2 days ago I noticed these brown things in my Duncan but I didn't do anything about it. Parameters are good except for my phosphates and all of my parameters are pretty stable. Any ideas?
Salinity 1.024
Nitrates 5ppm
Alk 7.7
