Help..I may have killed my sea urchin.

So I added some trace elements to my tank (Kent Trace Elements), but after I did that I saw it contained Copper EDTA. Now my urchin is on the tank floor and has lost some (not all) of its spines. However, my limpets are doing fine. I know copper is bad on inverts and thats made me freak a little after I saw it.

The last time my urchin "hid" from me and dropped spines it came back bigger and with longer spines. Trust I had a major face to palm moment.

How much did you dose in what size tank, just want to see if maybe you accidentally overdosed. I occasionally dose the exact same thing in my tank and none of my inverts ever responded negatively

29 gallon and I did 2 capfuls however much that equals. 1 or 2 mls maybe.

Just went downstairs and two capsule = 10 ml. Note I filled the cap to the brim

So then im wondering if I did kill my urchin. But wouldnt the copper affect all of the inverts in the tank?

I'd imagine that it would but I don't know how long it would take for them to show wesigns and we still don't know if this is the cause. Just to be on the safe side, I would do a water change and invest in a measuring cup or dropper

IM also going to get a copper test. Im hoping that maybe my urchin, which was actually a live rock hitchhiker, is just getting bigger (fingers crossed).
