The API Copper Test Kit provides a simple and accurate way to measure copper concentrations in your aquarium. Copper is a common and effective treatment for many external fish parasites, but it must be maintained at specific therapeutic levels. This kit is essential for monitoring these levels, as concentrations that are too low will be ineffective, while levels that are too high can be toxic to fish and lethal to invertebrates.

This comprehensive kit is capable of performing up to 90 tests, measuring copper levels from 0 to 4 parts per million (ppm). It is designed to measure both free and chelated forms of copper, ensuring you get a complete and precise reading regardless of the type of copper treatment being used. The kit includes a glass test tube, two reagent bottles, and a clear, easy-to-read color chart for fast and reliable results in both freshwater and saltwater aquariums or ponds.

This test kit is indispensable for any aquarist who is quarantining and treating fish with copper-based medications for parasitic infections like marine ich or velvet. It is also a valuable tool for hobbyists who want to test their source water for copper contamination, ensuring a safe environment for all aquatic life, especially sensitive invertebrates like corals and shrimp which have a zero tolerance for copper.
