I have a new 120 gallon tank dedicated to SPS corals. It has cycled and all parameters are with in acceptable ranges. The corals are new (4 weeks old) and I know they will take awhile to color up. I ask this question because I had to move my fish to a quarantine tank due to an out break of ICK. So the only live stock in the tank right now is a small clean up crew. The corals look about the same as the day I put them in except for one of the corals is bleaching on one side (not much). My last water change and test was 4/28/13 and the parameters were the following:
NO2-0
NO3-0
SG-1.025
Phosphate-.04
ALK-8.9
Mag-1350
Calcium-440
I was wondering if the bleaching is due to too much light too soon or no food for the corals since there are no fish in the tank. My lighting schedule is 8AM -8PM Actinic and from 10AM - 4PM MH. I have a par meter and took reading by each coral and they do not seem too high but I could be wrong they are 325 - 465 by each coral the one that is bleaching is 375. If I should be dosing Amino Acids and such which products are recommended?
Thank you
