Review: Worked like a charm - This copper test kit worked well when I had a bout of ich that I needed to treat in my 55 gallon tank -- I used Mardel Coppersafe (now being resold again by Fritz Aquatics). I didn't have any trouble reading the level of copper when I looked down through the tube after placing it on a light colored surface (sheet of paper works well). I will say that this kit did NOT work with the Kordon Copper Aid that I originally purchased from Petco, but seeing as I ended up having to buy the Mardel to get rid of the ich, I think it was probably something with that medication and I was afraid of overdosing because the instructions and the level of copper according to the test kit weren't even close in lining up. All in all, recommended if you are treating your tank with a copper-based medication. As a side note, my tank is planted and has black fin corydoras in it and both suffered no ill effects. ## Features - Contains one (1) API COPPER TEST KIT 90-Test Aquarium Water Test Kit, including 1 bottle of testing solution, 1 color card and 1 test tube with cap - Helps monitor copper and prevent invisible water problems that can be harmful to fish or treatments ineffective - Accurately detects copper levels from 0-4 ppm - Low copper level could make parasitic infections treatment ineffective - Use for weekly monitoring, when water or fish problems appear and when medicating ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.4 out of 5 stars 814 Reviews | ## Images ![Copper Test KIT 90-Test Aquarium Water Test Kit - Image 1](https://m.media-amazon.com/images/I/81XNXAO7z9L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very easy to use and understand results. *by L***B on March 17, 2026* Very easy to use and understand results. ### ⭐⭐⭐⭐⭐ Worked like a charm *by K***N on August 9, 2016* This copper test kit worked well when I had a bout of ich that I needed to treat in my 55 gallon tank -- I used Mardel Coppersafe (now being resold again by Fritz Aquatics).

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. ## Frequently Bought Together - API Api Copper Test Kit 90-Test Aquarium Water Test Kit - Copper Power (Endich) ACP0016B Blue Treatment for Marine Fish, 16-Ounce - Seachem Ammonia Alert, Aquarium Test Colour Changing Indicator --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.mx/products/34863656-copper-test-kit-90-test-aquarium-water-test-kit](https://www.desertcart.mx/products/34863656-copper-test-kit-90-test-aquarium-water-test-kit) --- *Product available on Desertcart Mexico* *Store origin: MX* *Last updated: 2026-09-22*
