First time doing copper qt… I have a 60 breeder with marineland emperor 400 hob filter. Comes with these filters which has some activated carbon in them. I read somewhere you shouldn’t run carbon with copper because it will deplete the copper.
Are these safe to use in a qt tank with copper or should I use something else inside the marineland hob filter??
