I already use Prime for all my water changes does Prime actually reduce copper as long as it's like very low levels?Look under your sink or where your hot water tank is located. If the pipes sticking out are copper then that answers your question. Lots of homes have copper so I'm not sure if that's a real concern for shrimp. Use some Prime if you are worried.

Alright thanks well either way I'll keep dosing Prime because it's so cost efficient and amazing IMO. Thanks everyone for the feedback had to confirm itthe amount of trace copper element that would be in your water would be so minute it would not matter. if you are actively using your plumbing in your house for showers, dishes, washing clothes, brushing teeth and flushing toilets your water would move through your pipes...there would be little to zero copper in your water. Use prime if you are worried but I doubt you need that. I would be more concerned about chlorine or chloramines.
