If you have plants in your aquarium, the copper will either stunt them or
kill them eventually. Stick with plastic or stainless steel.

I just replumbed my entire house with copper, and I have some left over. I
am thinking about building a DIY filter for my aquarium, just for fun. Any
thoughts on the safety of using copper in an aquaria environment? I figure
it safe for us to drink, it should be safe in the tank or pond for that
matter.

Any thoughts?
