I have a 10g qt and added 10 drops of cupermine the first day and 10 drops the second day. I’m just waiting for 48 hrs to pass before adding more. I did a test using Hanna copper checker and my results came back to 0.52, isn’t this the amount we want to be at? do I need to add more after the 48 hrs are up.
