After 2.5 years of growing from 1 head to 14 heads + dropping new ones, my hammer corals are now receeding. The smaller one with 4 heads is already showing skeleton. It started about 3 weeks ago. Water parameters:
Temp: 77.7
pH: 8.38
Salinity: 1.024
NO3: 0 (Salifert)
Alkalinity: 9.3 (Salifert & Hannah)
Ca: 460 (Salifert)
Mg: 1200 (Salifert)
PO4: 0.05 (Hannah)
Tank: 29g Biocube, no skimmer, Chaeto with grow light in chamber 2, UV light in chamber 1.
I don't have a clue why this is happening. Has anyone experienced this?
Any idea what I should do? Thanks in advance.
