Seachem MultiTest النحاس

The instructions were clear enough that I could measure both ionic and chelated copper, which is exactly what I needed for my reef tank after dosing treatments. The titration method gave me a precise endpoint without the guesswork I dealt with on my old strips. Took about ten minutes to run the full

Finally, a copper test that actually reads both ionic and chelated forms accurately. The titration method is much clearer than the compleximetric kits I've struggled with before. Saved my tank during treatment.

The titration-based design is a nice upgrade from the cheap dip strips I used before. It accurately measures both ionic and chelated copper, which gives me peace of mind for my sensitive fish. The instructions took a moment to get used to, but the results are reliable.
