Hi all. I have a 9 month old tank. I hope to be heavy SPS. I am running carbon, GFO, vinegar, alk, and cal. I have 2 Ecotech Radions w/ TIR lenses for lighting.
About 4 or 5 months ago I ordered 35 SPS frags from Mr. Coral - to get my SPS collection started - Plus I wanted to test cheap frags before investing in more expensive LE SPS pieces. I lost 5 DOA or within a week, leaving me with about 30. Today, 25 of them are doing great. Great coloration and good growth. They have encrusted their frag plugs and grown on to my live rock. 5 of them, however, are dying, and have been receding or looking crappy for a long time now. Here are 2 high-res photos of them on my frag rack. As you can see, there is living tissue on them still, and you can see the PE. But then there are those bare spaces sporadically on them. Back 4 or 5 months ago, they were all tissue with PE, so they have receded, but in a patchy way, not top to bottom or bottom to top. I don't see flat worms, red bugs, or nudi's on them, nor so I see bite marks, etc. I figure some SPS make it, and some don't, and maybe these just aren't going to make it for some random reason or another. I haven't tossed them yet because they do have the living tissue on them still. Maybe there is a way to save them. Clip off the dead parts, or dip them and keep them on the frag rack and see if they can recover, etc?
Anyway, has anyone seen SPS like this? Does it look like anything you've experienced before? My parameters are all good and have been stable for 6 months now. (Currently: Cal = 400; Alk = 8).
