Hi guys, I got a 40gallon qt that’s measuring at 2.25ppm copper (dosed copper power and checked with Hanna). I just started the 30 day countdown yesterday as I plan on keeping them in copper for at least 30 days to kill off the ich. Is 2.25 too much? Should I be worried about keeping them in 2.25 for 30 days?
