I went to my LFS one day a while back, and a new guy had gotten confused on
instructions from the store owner and accidently dumped a bunch of copper
into the reef animal sales tanks. He didnt realize he had done anything
wrong and thus did not mention it to anybody. Well, somehow during
conversation a couple of hours later, it was realized that he had made this
horrible mistake. Upon closer inspection of the tanks, it was obvious
something was wrong. The corals had begun to close up, and the snails in the
tank were on the substrate, not moving much. Immediatly, the guys pulled the
corals from the sales tanks and jammed them into the one display tank the
store had. By the time this was done, all of the snails were pretty much
dead. I dont think any of them made it. The hermit crabs however were a
different story. They didnt miss a beat, and actually benefited by making
and easy meal of the dead snails. Some of the crabs were never removed from
the system at all, and none of them were lost (at least not due to copper).
The corals all recovered and were fine after about 24 hours. It would seem
that the poor snails were the most succeptible to the copper.
The owner did 100% water replacement. He then ran copper remover at double
dose for 2 doses, then did the same with carbon. Two weeks later he had the
sales tanks completly re-stocked and the corals he puts in them do fine, as
well as the snails and starfish.
Now, the LR he had in the system he removed any put in his FO tanks, so I am
not sure about that. But it would seem if you do the water changes, and run
a quality copper remover for a while, you should be okay even with LR. Maybe
run the copper remover and then afterwards, plop a snail in the tank and see
how it reacts. If it dies, you know its not ready. If he lives for a few
days, chances are your corals will do fine as well.
Just thought I would share that!
