Actually I'm still gathering data, its only been a day and half since I posted this. I am also still waiting on the delivery of my ORP monitor so I can't do anything until I've decided on a course of action.

Sounds like some of your sps are doing better. I'm no expert and I might be completely off but if things go downhill again I would suggest looking at your lights. Having seen your tank first hand I can say that it allot of lighting for a small tank. If you have an extra halide, or oven a different reflector (one not so good, so pretty much a downgrade) and see what happens. All your other levels and everything seem good so I would investigate the light a bit more.

Maybe I will swap out the reflector for a week, and try that. I only like to try one thing at once though. I guess though doing a reflector swap would give me a week or two in the very least to search out other ideas.
Jason can we discuss the lack of slime a bit more? Are there any other causes?

I have another reflector on hand so its a cheap change.
If I were to add gauze or screening over the reflector what should I do? Cover it all, or just parts of it at time? If its light burn the I assume in a week or two I will start to see darkening of the SPS. Maybe brown out, or just a change in coloration.

C,
I have seen the slime coat lose in my own tank. It has occurred with High SG and again with a fist spike of ALK. Basically the coral starts to look dull and there is no polyp extension. I believe it is a recoverable situation as 4 or 5 of my corals have recovered. But others did not. The next stage tends to be tissue lose and growth of algae on the skeleton. Unlike RTN or even STN the lack of a slime coat (IMO) indicates a slow progression of a stressed coral with 2 outcomes a return to health or death. I don't think this helps too much with the diagnosis of what is causing it but instead leave us right where we are. What can be stressing your corals. We have ruled out measurable water parameters We have ruled out chemical or other coral attack (usually kills small sections of coral) We haven't ruled out silicone leaching We haven't ruled out unmeasurable water parameters (contamination) but you would think it would effect everything Light sure is a possibility. your running a 150W DE right? what is the UV is not being stopped? That would do it J

How would I go about testing for other contaminants? I contacted AWT in the states and finally got a response, they can't test Canadian water as they can't ship it back to us, and we may have problems getting it to them. Does anyone know of similar businesses in Canada?

The only other thing I can think of that others haven't really mentioned is to try taking out the frogspawn. I had sps in a tank that had frogspawn (as well as many other corals) and the sps started bleaching and the flesh started to fall off. I moved the sps corals to another tank that only had zoos and gsp in it and the sps made a full recovery. I don't really know for sure if the frogspawn was fighting with the sps or not, but if you have another tank the frogspawn could go into, it would be easy to rule it out.
