Help

Help, I have been running my 75G BB SPS tank now for a little over a year now. Everything has ben doing great, growth, color, all parameters have been fine. All of a sudden on my Cali Tort, I started noticing less PE, then a couple of the tips started to slowly start to lost tissue, all the while these same tips were sort of, "spiderwebbing". My parameters are perfect still, and I haven't added anything recently to my tank that may have brought in some sort of bug. The one change I did do was to add a remote DSB to lower my nitrates. They were at 7ppm, and are going down. But, around the same time, maybe even a little before this started(don't remember the exact time frame)
Anyway, here's some pictures of what I'm talking about, it doesn't happen on every coral and many are still thriving, but, some of them still are affected by whatever is causing this.

Thanks for any help.

Have you read through some of the other threads on here about SPS bleaching? Maybe worth the read...see if there's any simularities to any of them?

If anything in any of those threads relates to your problem, let us know, we can take it from there.
