I am setting up a qt to treat for ick. I am going to use coppersafe. I am wanting to put some limestone in for hiding. Is this okay? I was also thinking about putting my protien skimmer on the qt. It is a hob pro prizm. Does acrylic absorb the copper? I also have hob filter that I am wanting to put on the qt it is made of some kind of black plastic. Will this make it unsafe to put them back on the main when I am done. Will they absorb the copper?
