Hi everyone,
Two days ago I noticed my hammer coral curled up, almost no polyp extension and really looking not that fluffy/happy...
The next morning the situation was unchanged but I noticed some of the polyps had let go, or were letting go at the moment.
Sorry for the bad quality picture, my iphone has some troubles with these close ups. You could also see the mouth very clearly, something I didn't notice before:
On the picture above you can see some of the hammers polyps have let go and it's mesenterial filemants are coming out...
The hammer was the first coral I bought and doing absolutely fine. It's been in the tank for almost 4 months, with no problems so far... The tank is up and running for 7 months so far. Beside some mild dino outbreaks, nothing 'bad' happened at the moment'. (ps. all other corals are doing fine, this is the only one showing signs of stress )
This picture shows how the coral normally looks when its happy.
I have absolutely no idea what caused this problem.
I performed my typical waterchange the day before, 25% on my waterbox cube 20, with Tropic Marin reef salt pro.
This are the water parameters I have at the moment:
salinity: 35 ppm
pH: 8.15 pH
alkalinity: 6.4 dkH (bringing it up to 8 dKH, dosing around 0.25 dkH daily)
ammonia: 0 ppm
calcium: 450 ppm
magnesium: 1380 ppm
nitrate: 2 ppm ( dosing 1 ppm daily with KNO3-solution)
nitrite: 0 ppm
phosphate: 0 ppm ( dosing 0.01 ppm daily with KH2PO4-solution)
I run carbon, no gfo, no skimmer.
Can anyone help me out?
