Hi Folks,
About 10 days ago I purchased a nice plate coral which was doing fine in my tank until yesterday when I noticed that it was beginning to turn brown. This morning I can see that parts of the skeleton are now visible.
I am using the normal RSM salt as I had high mag problems using the RSM Coral Pro variety.
The coral is placed on my sand bed, in a moderate flow of water and moderate lighting.
I initially tried to feed it Fauna Marin pellets twice, but on both occasions it half swallowed these only to bring them back up and not pull them in again. I then switched to mysis shavings which it's eaten twice.
The day before things started to look bad I did a water change, but nothing that would have knocked my params by too much in any way. Speaking of which:
Temperature: 26.2c / 79f
Salinity: 34ppm
pH: 7.8
Ammonia: 0ppm
Nitrite: 0ppm
Nitrate: 0ppm
Phosphate: 0ppm
Calcium: 400ppm
Alkalinity: 7dkh
Magnesium: 1350ppm
To me the pH seems a bit low? It used to be 8.2 when I was using the RSM Coral Pro salt, but has gradually settled down to 7.8 with each water change on the regular RSM salt. Perhaps Alk is a bit low too?
My tank is mostly softies, but my two other LPS (Duncan & Blasto) are doing great.
I'd really appreciate some help - I really liked this one and it's a real shame to see it perish
