I have many aptasia and was told to try to use Joes Juice to get rid of them. I used the Joes juice and it did get rid of some of the aptasia. However, when I woke up this morning my yellow tang had died. The other fish in the tank seems to be panting. The instructions on the joes juice didn't say anything about lowering the O2 level so I only performed a 25% water change. What does anybody know about my problem.
