Some of you may know me, and unfortunately I am a recurring theme on these threads. School started for me two days ago, and since then I’ve had to wake up at 5:45. My lights are usually set to about 8:30 to 9:00, but they came on at 6:30. When I got home from school there were more dinoflagellates than I had in the previous three weeks covering shells and GHA. Could an unusual lighting schedule cause such a relapse? Anyways after a 1-2 day blackout they’ve all went from a deep brown/red to a very light brown indicating that they’re either dead or dormant. I’m gonna siphon out any remaining particles on the base, and remove as much dead GHA as possible. Has anyone had this happen to them, and if so, what did you do? Dino species: prorocentrum
