Magnesium (MG) Test Kit

Saliferrt magnesium testing is very good accurate i recommend highly for marine testing.

Good testing kit for magnesium.. always test your tank.

I run several marine aquariums. I manually test 6 parameters on each tank twice a week, have tried every single brand of test kits over the last 5 years or so, have owned automated testing systems (and found them completely inadequate and generally inaccurate), and routinely send in samples for ICPOES testing to confirm my manual results. This is clearly the most accurate hobbyist test currently available for magnesium. The test is easy to perform with a clear endpoint to the titration. Salifert recently shortened the test process by one step, making it even simpler to perform, without loss of accuracy. Some may be tempted to switch to the new Hanna magnesium checker. Don't do it. Overall, Hanna makes great hobbyist checkers, and they are my first choice for several parameters. Unfortunately, not so for the Hanna magnesium checker, which consistently gives reading of about 100 ppm lower than the actual value. I was frankly stunned how badly they flubbed this one, considering how good their gear is overall.

Simple comes with instructions and easy to understand.

Weird usage watch videos online to see how.

Easy and accurate for testing Magnesium in saltwater aquariums. I've used this for years and it's excellent! That said, open your shipment *carefully* - doubly so if it arrives in a soft bubble-pack envelope. The box includes a red or pink removable tip for the reagent syringe. That tip can go missing if the box is crushed. It's harder to go missing if it arrives in a box. Return the product *unused*, for a replacement if the tip is not present. It's required for accurate testing!

I often need to use the thing, my saltwater aquarium every week to test the water quality, easy to use, easy to operate.

I have a 72 Gallon Bowfront Reef tank. It is imperative to have proper magnesium levels for proper calcium and alkalinity stability. This test kit is accurate, easy to use and read. I had no problem with my first test. It precisely matches the test I had performed by our state university. I was relieved to see that my test was identical to the state test. Imagine my relief to see that I am achieving a successful and healthy environment. Viva la Nederlands!!! 😂
