War coral discolored

[Courtney Lovell]

Any ideas guys? It started getting discolored and it was suggested to move him to more shaded area. Which I did. Checked water levels and all are within normal range. Biweekly 30% water changes and cleaning weekly. Any suggestions on how to make him happy? All others are doing great. On a side note he has been near the top in a high flow area for about 4 months and seemed fine. No real growth but color was always the same. Not sure what changed to make him sick looking


Thanks

What are your parameters? That might help us.

to me it seems that the salinity is a little low 1.025 is the norm around here. what does your Alkalinity and Calcium look like? Might as well look at the Magnesium while we're at it....

the reason i bring up the Alk and Calcuim is i had an Acan start looking like your war coral and i strongly believe that it has to do with the Alk being low. I have been fighting to get mine up about 7 dKH and its stuck at 5dKH
