Review: Very easy to use and understand results. - Very easy to use and understand results.
Review: Excellent test for testing Cupramine - Initial review: After following the instructions very specifically, I was unable to get a reading of copper after I dosed Cupramine into my 10 gallon quarantine saltwater tank. However, after letting the test tube sit for a day, I was able to get a copper reading. Read below for the full review and results: 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.

### ⭐⭐⭐⭐⭐ For experienced hobbiest
*by R***4 on June 10, 2024*

I've been doing marine/reef tanks over 30 yrs. And reviewing experienced fish Keepers, you can learn a lot. Use of copper for fish parasites is highly effective, but deadly if strict instructions are not met! This copper test is ok for experienced fish/aquariest. But i recommend a more accurate for the beginners and novice hobbiest. And most of all, time and patience must be followed.
