Testing the Waters
In order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness and even loss. Most common water quality parameters are Ammonia, Nitrite, Nitrate, and pH. All may vary over time and all are invisible to the eye which is why it is important to test weekly. Testing aquarium water weekly will aid in keeping your most important water parameters within the proper range for your aquarium. Choose from a wide range of API testing options, such as our popular FRESHWATER MASTER TEST KIT or 5-IN-1 TEST STRIPS, for accurate water evaluation. Regular testing will help you easily determine your aquarium conditions.

Important information
Directions
Copper is often used to treat 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 level. Copper should not be used in aquariums with invertebrates, including snails, shrimp, crayfish, and corals, as well as in aquariums or ponds with plants. This test kit reads the level of total copper (free and chelated) in parts per million (ppm) which are equivalent to milligrams per liter from 0 – 4.0 ppm. Chelated copper compounds are very stable and will remain in solution for long periods of time. Free copper levels will decline rapidly and must be tested daily.

EDIT: After letting the test tube sit for an entire day, I can actually distinguish a copper reading that seems to be nearly accurate with the amount of Cupramine I dosed. I tested ANOTHER sample of the same water, and got copper color immediately? Both tests look identical and it is actually reading right about 0.5mg/L. I am not sure if I should trust the readings, although they would be spot on with the amount of Cupramine I dosed. I'll test it with a Seachem test kit tommorow and update this review. Also make sure to follow the directions precisely, you need to remove the cap and look down the test tube with the white background of the color under the tube, but don't let the tube sit directly on top of the card, the color will appear much darker. Hold the test tube above the card an inch or two.
EDIT #2 02/19/18: The Seachem Copper Test kit arrived and the results are in: 0.5mg/L. Right at the amount I dosed. Tested again today with also the API Copper Test kit. Results again, are the exact same. 0.5mg/L. This means (in my case) both the API Copper Test Kit and the Seachem Test Kit are both precise measuring tools if you are dosing Cupramine.

I just ordered the Hanna copper high range checker as was suggested by humblereef and other aquatic sites. If accuracy is important, don't waste time or money trying to cut corners with this.

This works and it appears to pick up even trace amounts.
Distilled water has none according to this kit just as you would expect,
Tap water has just the tiniest amount, so it's good to know it can pick up such a small amount.
