Scuz....positive. just rodi water and oceanic salt, and only about 10 gal of it too. The qt tank I filled using water from my main system. Thing is only my tangs died, the blue chromis are fine. Just checked copper levels again and they are less than .25. Didnt even get a chance to up the dose to correct levels
Most ammonia tests don't work with copper; the little stick on ammonia alert badges. With two tangs, and other fish, in only 10 gals of water with no real bio-filtration-----it sounds like ammonia. Chromis can handle a lot more ammonia than tangs.
