The colorimeter is a must have addition for your daily usage.

The Hanna Instruments Copper High Range Checker (HI702) is a simple, accurate, and cost effective way to measure high ranges of copper. While using copper treatment, it works as a disinfectant and makes the fish suffer less while going through treatment easing their irritation. It’s extremely accurate and consistent. Essentially this is useless for telling if you have successfully elimated copper from a system but is great for getting the actual therapeutic levels right when treating fish.
