Damn, sorry to hear that Ant - definitely going with toxicity now. Pull out any filtration media you have in there - even if its ceramic. Check the impellor shafts on your MP40's (not sure what they are made of). Check inside your return pump.

Wow that went downhill quickly. Seems like one of those phenomena that isn't understood fully yet, so really sucks that you were a victim. Even Eric Borneman didn't really pinpoint the cause in aquaria, from what I found anyway. Just that it is stress related.
Did you ever try removing the leather? It's a pretty beasty one, so if it did go into warfare mode could have a big impact?
My other thought is metal poisoning ... somehow? Anything at all in your tank that could be leaching?
I can't remember, but do you have a QT tank? I would be moving any remaining LPS to another tank, see if the problem continues. Given you have done a 100% water change there must be soemthing your tank causing this. Unless the NSW itself is affected?
Fishing for ideas now because I don't want to see you bailout of marine given how far you have come, but understand you feeling that way right now.

I would be really interested to know the source of the NSW. Especially if it is from Sydney. There is some horrible pollution around including heavy metals and dioxins. Surely trying ASW could fix any problems. Or if the NSW source was known, there would be ways to find info about water quality and chemical impurities from the water authority, local council or environmental agency. They might even like to know about quality issues. All assumptions. But I think trying ASW could be just one way to control a primary source of possible contention.
I am very skeptical about it being NSW. It doesnt just all of a sudden become contaminated. The NSW I have stored had been in the tank for months and then I used all the rest changing the water over then got another delivery and threw about 800L through the system. It is collected at Dolans Bay and many people in Sydney, including people on the forum use the same guy. I will not be adding ASW, no more money is going into this.
I doubt it is the pumps also, I had 2 of them die so replaced with 2 new eheims. This was before the system flush so if it were pumps corroding etc it should have stopped.
It could be toxins but I am running double carbon 24/7 changing every 3 days I would think that it would take care of most of it?
Only thing I cannot find a reason that rules it out is parasite/disease?

I would be interested in the others using the same guy just commenting on whether they have had any issues lately... I just like investigating thoroughly. Dog with a bone.
I am so sorry for your loss mate. Xxx

Dude. Look at this. Dolan's bay is polluted with zinc and copper. You can get tests for that. Switch to ASW. I will buy the salt for you and lend you my RO maker if you like! I'll give you frags. I only have 4! You can have them!!!
PLEASE DON'T GIVE UP!! *clings to your arm and wraps self around your legs and begs*

On this note: I have a friend who discover after a couple of years of doctor visits he had copper poisoning. He had to change his diet and take lots of medication. It's obviously worse for water based life.

Copper is in alkalinity, calcium & magnesium supplements used in Two-Part supplements. We don’t want to add too much of these supplements at one time. This gives time for the organics in the water to attach the copper and make it less toxic. It also allows tome for the copper to bind to surfgaces like rock and sand, reducing its availability to most organisms. You want to use chemically pure supplements with the lowest levels of copper. Using deicers may be risky since we don’t know their copper level. You do not want to increase the calcium and magnesium level by more than 100 ppm using Two-Part supplements due to this type of concern about impurities.
I believe you have heavy metal poisoning. I would strongly recommend testing the water or seeking out test results. A more recent report also shows mercury, copper and others.
I understand your reasons for giving it up.
If anyone is interested, here is another report on the area:

*sigh* bummer. There goes that theory. Thank you for testing to satisfy my hyperactivity.

I appreciate you trying to help @ezza , you are all so kind
We need an autopsy for the victims to determine COD
I might try to contact the authors of the study that produced these results and see what they say as to the suitability of this area for supplying NSW. Quite frankly... I wouldn't use it myself. It just isn't that pure.

If your dosing malfunction caused the possibly minute metal traces to amplify in their toxicity it might have been enough to cause the die off. That's what it talks about in the first article... Bah. I wish I had access to a scientist in a lab.
