Okay so this may just be another paranoid reefer but I have 4 problems in my tank that I would like you all to look at, my water parameters are all zero 81 degrees 1.025 and 400w 10k mh, fourth in my series of questions is what can I do for what I think is a sick goniopora, I bought him from the lfs and didn't notic till I got home that on the back side part of it was dead or dyeing or whatever, so I put it under high current for a bit, dead stuff came off, but in this area as was before the tentacles there have a brown hue to them when compared to the front of the little guy which is bright green, hasn't gotten any worse or better in the 3 weeks or so I have it. what can I do to fix it. Please see pics attached.
