Looking for help/suggestions… I’m losing my LPS one after another. The losses started 2-3 months ago with a plate coral that came in damaged and an Acan from the same shipment, and the issue has been gradually been getting worse and moving faster ever since.
Now I’m losing corals that have been established and growing for six months or more. So far it seems to be mostly limited to corals that are on the sand or low on the rocks, and LPS only (acans, favia, goni, alveopora - just retracted today, cyphastrea). Some other nice favia and leptastrea not yet affected. Euphyllia, chalice, and various SPS higher up on the rocks not yet affected. Zoas not affected.
Parameters have been fairly stable and are currently as follows:
ALK: 7.9
CA: 430
MG: 1400
NO3: 4.8
PO4: 0.07
SAL: 1.025
PH: 7.9
Temp: 77.5 F
10% water change weekly. No change to salt. No change to lighting schedule. No change to flow. ICP test doesn’t show any major deficiencies or contaminants. Sent away a water sample to AquaBiomics on Tuesday but it will likely be weeks before I get results.
Thinking maybe it’s a bacterial infection. No visible signs of pests. Started pulling the affected corals for a daily cipro bath yesterday. Pics below. Any suggestions? Thanks!
