Not sure what's the cause.
It's a new tank. About 5 months. All params are tested weekly and in order now,
however I regret using nopox at 1ml a day in the 90gallon. I think it was the cause for an algae/ dino outbreak since I had 0 nitrate and low po4 at the time. The rocks had a mat of dark brown algae like material in the photosynthetic areas. I cleaned most if it off but refer to the pics to see some of how it looked. Now my nitrates are 5 and po4 .04.
Also on the dead sps bird's-nest if I zoom in i can see little worm like things moving around , looks like dino, but not sure if it's normal since it's already dead (clean up or cause)? The healthier sps in the pics have a brown fuzz on tips or base.
