API Copper Test Kit

Allows easy and accurate monitoring of copper levels to maintain copper-based fish treatments at therapeutic levels. Copper, a common treatment for many parasitic infections, must be monitored in an aquarium or a pond. The copper level can drop too low for the treatment to be effective, or can increase to a point that is detrimental to fish health. Copper may even be present in your tap water. Tests copper levels from 0 to 4 ppm. Includes dropper bottle for accurate dispensing of test solution, easy-to-read instructions, and non-staining glass test tube with snap-tight cap.

Please click on "More Information" for the importance of testing for copper and directions for use.

Copper should not be used or be evident in aquariums with invertebrates, including snails, shrimp, crayfish and corals, as well as in freshwater aquariums or ponds with plants. Tap water may contain copper leached from pipes and, ultimately, it can accumulate in the aquarium.

Directions for Use:
This kit reads total copper level in parts per million (ppm). This kit works in both freshwater and saltwater aquariums.

Read thoroughly before testing. Do not allow test solution to get into aquarium.

To remove childproof safety cap: With one hand, push red tab left with thumb while unscrewing cap with free hand.

1. Fill the test tube with 5 ml of water to be tested (to the line on the test tube).
2. Add 10 drops of copper test solution, one drop at a time, holding dropper bottle upside down in a completely vertical position to ensure uniformity of drops.
3. Cap the test tube and shake the tube for 5 seconds. Keep count of the drops being added. Do not hold finger over open end of the tube as this may affect the test result.
4. Wait one minute for the color to develop.
5. Remove the cap from the test tube and while holding it over a white background on the test strip (included) compare the color of the sample with the colors on the test strip. Even a very faint color indicates the presence of copper.
