Description for API Copper Test Kit
Test reads 0 to 4 mg/L or parts per million (ppm) of copper. Helps to maintain a healthy aquarium or pond for fish by ensuring that copper (a common treatment for many parisitic infections) levels are within the healthy range. Test kit of 90 tests.Importance of Testing for CopperCopper is often used to treat many parasitic infections on fresh and saltwater fish. To be effective, the copper concentration in the aquarium must be maintained at the therapeutic level for several weeks. Frequent testing is required to monitor the copper level in the aquarium. Some fish species are very sensitive to copper treatments. Therefore, follow the copper treatment manufacturer's directions carefully.Copper should not be used or 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.Testing TipsThe Copper Test Kit reads the total copper level in parts per million (ppm) which are equivalent to milligrams per liter (mg/L) from 0 ppm (mg/L) to 4.0 ppm (mg/L). The Copper Test Kit works in both freshwater and saltwater aquariums. The color chart provided with this test kit should be used to test for copper levels in fresh and saltwater aquariums and ponds.Directions for Testing Copper Levels: 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. Fill a clean test tube with 5 ml of water to be tested (to the line on the tube). Add 10 drops of Copper Test Solution, holding dropper bottle upside down in a completely vertical position to assure uniformity of drops added to the water sample. Cap the test tube and shake the tube for 5 seconds. Do not hold finger over the open end of the tube, as this may affect test results. Wait one minute for the color to develop.

I know some have said the colors are hard to distinguish. I didn't find that to be true. The colors are pretty light, but as long as the tube is up against a white background it is pretty clear if the GH one is pale green or pale orange, or the KH one is blue or yellow. If you are mildly colorblind this might be rather hard.
Being a titration test, you basically add one drop, shake it, and look at the color. Repeat until it changes, counting drops. This is fine for me, but if you have very high hardness it might take a while to run the test. My tap is 7dGH and 5dKH, and I raise the GH to 10. 10 drops doesn't take too terribly long.
Here's the thing though: a few years ago the freshwater color card (used to read the NO3 level) went from having 7 clear colors to choose from to having a muddled mess. At the low end of the range (where you would want your water to be), the colors are clear and decipherable. At the middle part of the range (where I tend to find things a bit too often), the colors start to look the same. Maybe it's just my eyes. I can see subtle variation between 10ppm and 20ppm and between 40ppm and 80ppm, but it's not enough to tell the difference when actually performing a measurement. Instead, I just split the difference and go with a generic "orange" is 15ppm and "red" is 60ppm. I can still pick out an intermediate "red/orange" that's around 30ppm, but I'd appreciate having a real color card capable of full resolution.
After 2 weeks of 0-.25 readings without fluctuation, I wondered if the tests were even accurate. I decided to test 5ml of pure ammonia instead. Imagine my disappointment when the pure ammonia sample turned the same yellow (0%). Before you go sending hate mail to API, there's a good reason for this. It turns out, the ammonia level was too high and essentially "blew out" the testing liquid. API is assuming your fish isn't living in pure ammonia and, therefore, didn't make this kit to test levels that high.
Next, I tested 5ml of water from a 1 gallon jug filled with tap water and 1 drop of pure ammonia. Yes, I apparently have too much time on my hands and a latent mad scientist gene. This test proved accurate. The tube turned dark green almost instantly (picture attached). I feel much more secure using and believing this test now.
This works well and I'm glad to add it to my tool kit.
