Salifert Magnesium Test Kit for measuring the magnesium level in seawater
The magnesium test kit can perform a maximum of 50 tests. The test measures accurate steps by means of color change during the test.
When testing the water, we recommend starting with the Magnesium test. If the magnesium level is much too low, it makes no sense to add other substances such as calcium if this value is also too low. The calcium is then hardly absorbed in the water and can therefore precipitate.
