    Like bleach, acid, alcohol, and fire: Copper is pretty good at killing things.

    We happen to be bigger things than most, so we have more resistance to it, but we’re not immune.

    I test my aquarium for copper fairly frequently because it i something that can kill my shrimp in small doses.

    They sell copper nails that can poison a tree.

        Honestly, in a stable tank with a solid ecosystem and no chemicals you shouldn’t need to test anything, usually.

        I just got the shrimp, and they’re especially sensitive to water parameters. I’m being cautious.

          I just keep mosquito fish, I swear they are hardy enough I could pour in bleach and they would just spit it back at me.

          Throw a penny in for decoration :0

          JK I love shrimp and have a ton. A while ago I used to fear copper too only because I once dosed a fertilizer with it and all my shrimp started to turn black. When I put them in new water it saved them though.
