Sorry I am really confuse. Maybe it's just me not interpreting your answer properly so I apologize. I am trying to understand why would a SPS coral die within a hour being in a mature tank vs. slowly die off (which can be caused by a million things). People dip corals in fresh water with various kinds of chemicals and the corals survive just fine. To have lots of corals die within a hour in a 1 year mature tank is just very wrong.

I know I not providing much help but I am still trying to understand how this all fits together before throwing out useless random guess. Let me try this again.

You have the tank for 1 year and you are growing corals very well because you said:

I have had all the corals for awhile and have I have sps growning very well since Dec.

but then in your original question, you said:

I am loosing corlas left and right and can not figure out why. The coral will look good then I go back an hr later and the flesh is melting away.

At what point did you start to notice this drastic change? Do yo happen to have a picture of the affected corals? Did you always get corals from the same source?
