Mistakes were made

[Greg B.]

Well. I made a post last week about my corals discoloring. Thinking that it may have been from dipping some of my coral. I narrowed it down to a used RODI system that I bought 2nd hand. The mistake that was made is that I didn't change the filters prior to using the water because I was impatient and didn't want to wait until the new filters resin and membrane came in. Long story short is all my corals have since perished. Some of them I've had for the last year. Problem that I am having now is what did this rodi unit put into my water to contaminate my tank? I have been running my carbon reactor since I noticed the color change in coral. All my water parameters were and still are stable and where I normally keep them. But now I'm scared to buy more coral because I don't know if the contaminate is still in the tank. I did a huge water change thinking that it would cut at least half of the contaminate out prior to the coral dying but it didn't change the rate of death. Where do I start now?

You need to get an ICP test to find out what is potentially still in your water. There are a LOT of possibilities and they differ depending on your source water.
