Yeah, sorry, I thought I mentioned this but I guess I didn't. I would think even a bacterial system will still take a least a week before producing any results, and you have a more immediate problem on hand.

I actually do still think this is a cycle. Whatever the cause, it's a cycle now, but I think it's even just a cycle that's self-escalating. (2-3 pages back you've got your parameters listed - and ammonia is present..) But the more I think of it, I think it's just that the move was enough to disrupt the processes, and a little cycle turned into a big cycle as things started letting go.

As for SPS and smaller clams in particular, these guys tend to be the most sensitive so, unfortunately, it makes sense to me that they are the first to let go.

I think at this point what you need to do is get whatever's left, that's still of a sensitive nature, out of there for a week or two. If you have any SPS left then those, and your remaining two clams, should probably be moved into an established tank. Softies might be able to weather this storm but I can't say for sure.

I think what your tank needs is basically just enough stability for the processes to re-establish themselves. It could take a few weeks but I'm sure it will settle out. It's just the "what do you do with the livestock" in the meantime.

PM me or call me if you want to use some of my tank space. I cannot guarantee survival but I'd do my best...
