Black ich

[nightmarepl]

hey guys, I’m currently treating my yellow tank for marine ich and I’m using copper power as the treatment source. The Ppm is currently 2.0 and been there for about 4 weeks now today i noticed the tang has black ich on it literally the same looking ich just black... he’s still in the copper so not sure how he has this?! Need advice....

maybe you should try polylabs. it works well and does no harm to fish
