I am currently QTing 4 clowns while my tank sits fallow. I have started copper to kill any potential parasites. I am using Seachem Cupramine. I added the last dose today to get it up to .5ppm.
My question is this: the bottle says to treat 14 days, but I’ve read in several places to treat Cu for 30 days. What’s the consensus here? I know Cu isn’t good for the fish, but at the same time I don’t want to reintroduce velvet back into my DT.
