I think that the problems are viral or bacterial, combined with tank conditions which weaken the corals immunity to attack by virus or bacteria. The viruses and bacteria may be unavoidable, or they might be introduced.

My basis for this conclusion is an experience I had a couple of years ago. I transferred RTN into a tank by bringing in a "sick" coral that I was trying to save. RTN moved outward from the spot where I put the dying frag, killing SPS around it. The closer the SPS was to the frag, the faster it died.

That's my thinking, FWIW.

I take it these bacteria or viruses you are suggesting would be SPS specific in some way? Maybe just leaving the tank fallow isn't enough to kill something like this off. Would this be something that ozone may take care of?

Since I already plan to run ozone on my 180g it can't hurt to try it out on this tank. I think that might be my next step. What I'm hearing is that the issue could be one of three things; equipment/food/drygoods/etc. (I'm starting to doubt this though since I'm almost run through everything I can test), chemical contamination (silicone, the glass), or third a biological contaminant.

This (Red Sea Aquazone Plus 200mg/hr) was what we were thinking of buying for the 180g. Do you think it could be controlled enough to use it on this 28g system for a few weeks? If ozone was the solution to the problem I would buy a more appropriately sized ozonier for this system.
