I know your concerned about the general well being of the whole ecosystem of your tank. It looks good. Ive seen alot worse and Im definately a newb. I do agree that something is missing and with persistance and patience you (we) will find the key to righting the problem the the coloration of corals and lack of fish longevity. IT will happen. Dont give up. YOur corals are living and not dying. that definatly means something of your reef husbandry. Again, dont give up.
I am trying Chromamax right now. I just started last week.
Its all they had local.
Do you think the colors will come back?
I still want to get the fish but the last bunch died again. I will order some when I can get another one to live. Don't want to spend $1000 on a fish (incl shipping) to have it die as well.
I'm sure the color will come back over time. I'm not sure how nutritious the ChromaMax will be, since it's dead phytoplankton. Plus, it won't really do much for the SPS. You could try pieces of fresh shrimp from the grocery store for your LPS.
I've tried the 'Max' Expert Series stuff from Kent before, but never really saw much of a response from the SPS. I've used Oyster Eggs, which is primarily for SPS. I would really like to try Roti-Feast.
