Really, no offense meant, but I would agree with RedVipe...it's hard to give advice after two months, too many of everything in your tank, and from what I understand from the explanation, some major losses in the beginning of those two months. You also say the LTA's came with torn feet...I highly doubt this. From having an anem that had a torn foot and seeing another at my LFS(not a regular runofthemill LFS either), I have come to the conclusion that a torn foot cannot heal. We have kept an anem with a torn foot for over 6 months, never to be released from his tray; he will never stick to rock or in sand again. Also, I always dose any frozen meaty foods for anything in my tank with Selcon...I would definitely not stop using it when the anem starts looking healthy. I do, however, agree that 1.023 is acceptable in a reef tank. 1.026 is about as high as you want it. The thing about reefs is they are usually understanding of issues. I've had my tanks over 1.030 and under 1.020 with minimal issue, but you should never get to those ranges(problem with my tss meter) and I would recommend 1.024-1.026. I think this is a happy medium that gives you a little room to play on each side...but not much, so always be careful. NSW is, after all, 34-36PPT in most cases.
Also, using a 90G reef as a hospital for an anemone is asking for disaster. If an anem craps out, bye-bye much of the reef.
Just my $.02. I am by far not an expert and I would not claim myself as one. I did, however, read many books, do a lot of experimenting, and been on these websites for hours every day. Go to rareclownfish.com or anywhere on here and I have a fairly stable(granted, not perfect) track record on information. I try to answer only questions I know or have strong feelings on. If someone asks something on a topic I don't know, many times I will do the legwork for them and do what they should do first: look it up on a few websites and find out what could be off from what they tell me.
