I think I might have had copper in my tap water so I changed to RO water (even if i don't have copper in my water i needed to change to RO water.) I did a 30% water change yesterday. Do I need to do something to get the copper out or will it leave with water changes? Do i need to add any additives with RO water? I have 5 fish and no corals but have the lighting for the corals and want to as soon as i clear up whatever is killing my inverts.
