How do we feel about using the same Hanna salinity checker for both water destined for your reef, as well as QT water with copper in it? Am I overthinking it?
I find myself with a few gallons of QT water dialing in salinity and copper levels, so new batches have some residual copper in it. Am I being paranoid thinking this is an issue? I always clean the checker in RO after use and let it dry completely before capping it and putting it away.
