I have been QT'ing an achilles tang for about 1 week now. He seems to be doing great, eats like a pig. I have been putting in Prime every know and then when my alert badge seems to be in between the yellow and green. This can't harm anything correct? I have been putting in the recommended dose. The only reason I am doing this is because I didn't have time to cycle the QT, I have had it up and running for 2 weeks. Also I am not dosing or going through any med procedures as I know this can render copper to high toxic levels.
