Copper cu+ test kit

Copper, a common treatment for many parasitic infections, must be monitored in an aquarium and pond, as it can drop too low for the treatment to be effective or increase to a point that is detrimental to fish health. The API^® Copper Test Kit enables easy and accurate testing of copper levels to maintain copper-based fish treatments at therapeutic levels, and tests copper from 0 to 4 ppm. It measures both free and chelated copper for your ideal underwater world!

Testing your water has never been so simple with API!
