coming to the end of 30 day treatment of copper power for ick in my D T, my concern is as follows, does all the copper need to be removed before I turn on my UV light again. Was reading that the breakdown of copper by UV will make it toxic. Anyone with knowledge on this subject, I would greatly appreciate it, Thanks.
