How long does it take for white spots to go away?

[Waynefish]

Hi Everyone, I've had a melanarus wrasse in QT for about 18 days now. The copper level, using Copper Power, is 2.42 as measured with the Hanna 702 checker. It appears to be eating well and swimming normally. However, it has small white spots on its fins (perhaps ich?) that haven't gone away yet. They've been there since the beginning of the QT treatment. Is it normal for the white spots to stay this long?

Thanks for your input!

Can you post pictures? Ich should’ve been gone by now but it could be flukes which don’t get affected by copper. It could also be injuries or lympho. Hard to say without seeing.
