The Salifert magnesium test kit works as advertised. Results are consistent with expected values. When I add magnesium chloride to raise the magnesium level by 100 ppm, the measured valued is close to 100 ppm higher. I even obtained good results when I cut the test sample in half, though results are a bit more variable, less precise., but this doubles the number of tests per box.

I have used this kit as well as several others for years. I like the Salifert Mg kit the best because I think it is accurate and easy to use. There are not a lot of steps involved. Its an important test to do if you have a reef tank. The price here is excellent. Lower than at my local fish store.

A very easy to use test kit and accurate. Checking your Magnesium levels is important and often overlooked by some hobbyists. This test kit is fairly simple -3 steps basically and you get your reading.
Overall it is a great product and it is costs less here than at my LFS.

With clear instructions, a small number of steps, and distinct color change, this Mag test kit is by far the easiest I've used. And with the results being very accurate and trust worthy, this kit should be in every reefers cabinet.
