    IMG_0484.JPG I had an outbreak of ich about 6 weeks ago from a powder blue that was fine for two months and after a water change one day decided to break out in ich , wiping out about a third of my fish! Everything I have tried adding just dies and I have added this blonde naso whom is ending up with the same discoloration as the one that died with the outbreak. But it does not look like ich at all to me.

    Looks like Brooklynella or a bacterial infection perhaps. Did you add any other corals/shrimps/rocks when the outbreak started? And do you do any carbon dosing?

    No carbon dosing. I do run ozone on a controller and UV. Always adding new corals etc. but always dip first.

    There is a good chance a fish disease came in on a coral, dipping won't kill every fish disease. Always a good idea to have corals somewhere in an established qt for 2-3 weeks without fish before introducing. If you are running ozone, white spot probably won't kill the fish, but other disease might. How are you running the ozone? Do you filter the water and air through carbon afterwards? And what is your ORP? Is there any chance the ozone molecules itself can get into the display and perhaps cause issues with the fish, it is highly oxidizing and even the gas itself can cause lung damage in humans if inhaled.

    Then a disease probably got in on a coral, as that does not look like white spot. White spot should also not kill so quickly, takes weeks for enough parasites to build up to kill fish, and with ozone running it should not kill the fish.
