Copper – a treatment for many parasitic infections – must be monitored in the aquarium or pond. The copper level can drop significantly, rendering the treatment ineffective, or it can rise to a point that is harmful to fish health. Copper may even be present in your tap water.

The API® Copper Test Kit allows you to easily and accurately monitor copper levels to maintain copper-based fish treatments at therapeutic levels, testing copper levels from 0 to 4 ppm. The kit measures both free and chelated copper and is suitable for use in freshwater and saltwater aquariums, or with ponds.

Contains 90 tests and includes one test bottle, easy-to-read instructions, a glass test tube, and a color chart.
