Just use an effective treatment like copper or hypo to kill ich. |
Does UV make copper more toxic?
I have never had problem with straight copper when using UV.
Would UV affect cheleted copper?
I have not used a cheleted copper for over 25 years so I can't say for sure.
The use of the UV during eradication of ich is to reduce the chance of bacterial infection during treatment against ich, when stocking new fish per se.
