Hello,
I need help specifically with my Acropora. I have a mixed reef that is coming up on 2 years old. Most of the corals look great. However I have many SPS Acropora (and 1 or 2 LPS) that are almost colorless or barely colored. These Acropora have been in my tank for almost a year now. When placed in then tank they had a very good amount of color. I have tried different parameters very slowly with no success. Here are my current parameters now:
Salinity - 1.026
Temp - 78.5
Nitrate 12.6
Phosphate - .10
Alkalinity 8.3
Calcium - 440
Mag - 1370
These parameters have been very consistent for the last year. I have tried small adjustments to include (6 months at phos - .05, Nitrate 5ppm/ 3 months at phos .08, nitrate - 10ppm/ and also 6 months of Alkalinity at 9. I decided to try and run a lower amount of Alk only in the last few months. My lighting hasn’t changed and I have happy Stylophora, Monti Cap, Montipora Digitata, Anacropora, euphylia and other LPS. Here is a pic of my whole tank as well as pics of problem corals.
