Hello reefers,
I have 2 hammers both with about 5-6 heads that over the past 3 weeks have started to turn white. My first thought was bleaching from light, but the odd thing, they are bleaching on the underside not facing the light. My tank is mostly euphilia and my lights haven’t changed in months. I have spent a lot of time getting the corals happy with light and random flow.
My Params:
Alk: 8.95
Ca: 478
Mg: 1349
No3: 9
Po4: 0.2
Salinity: 1.026
I have a trident and the alk swings about .3 a day depending on which time test is. I am auto dosing Aquaforest component 123. I know my po4 is high but has always been that high, my nitrates have fallen over last few weeks as my chaeto has been growing like crazy. Tank has been running for 18 months.
The strange thing, the corals are separated by about 2 feet, there are no bailouts, but polyp are receding. There are other hammers unaffected so far.
here are some picts, some with lights, some without. Sorry for poor pictures. Will bust out dslr if needed. Any help would be appreciated.
