Hello all,
I'm fairly new to reef keeping, and my tank has been established for about 5 months. Stable parameters all in range, alk around 9.3, nitrates 5 ppm or lower, and phosphates sometimes on the high side of .5 (I use a reactor to bring it down below that). Salinity is 1.026, calcium around 400 and mag around 1380.
I have this branching hammer coral that opens everyday completely and extends what seems to be a healthy manner. I recently added a second pink hammer that is not fully extended yet and has been sort of halfway extended for the last 2 days since I just added it.
I noticed when my extended happy hammer closes now, there is this wierd film that forms between the heads. I can't tell if it is brown jelly disease or something else, and why if it is, it is still extended just fine during the day. Attached pics of wierd film at night, and healthy extension during day.
Can anyone identify what is going on, and have you treated it before?
