The API Copper Test Kit provides a simple and accurate way to measure copper concentrations in your freshwater or saltwater aquarium. Copper is frequently used as a treatment for many fish parasites, but it is toxic to fish and invertebrates at high concentrations. This kit is essential for ensuring copper-based medications are maintained at a therapeutic level that is effective against parasites without harming your fish.

This comprehensive kit allows you to test copper levels from 0 to 4 parts per million (ppm), giving you a precise reading for safe treatment. It is designed to measure both free and chelated forms of copper, ensuring complete accuracy regardless of the type of treatment used. With the capacity to perform up to 90 tests, this kit offers excellent value and longevity for managing your aquarium's health or checking for copper contamination in your tap water.

This test kit is ideal for any aquarist who is medicating fish with copper for parasitic infections like marine ich or velvet. It is a critical tool for maintaining the delicate balance between an effective dose and a lethal one. It's also beneficial for hobbyists setting up a new system to test their source water for unwanted heavy metals, ensuring a safe environment for all aquatic life, especially sensitive invertebrates in a reef tank.
