Yes PH is above 7.8 , ammonia even right after wc is still around 1ppm but I’m using seachem prime.
Mimic comes out more today but goes back to pvc pipe. And all I can see is his tail so can’t get to take good pic or have a good look at him.
Hippo tang and eibli tang I don’t see any more white spots or dust on body but I see them zooming around tank appears to be scratching or flashing on the heater. They prob had ich in addition to velvet?
Oh - 1 ppm ammonia measured with what test kit? Run a search here on Prime and ammonia control. People have had issues with it not really helping. I use Amquel myself.
Scratching/flashing are more of a sign of flukes than ich.
