Colombo Magnesium Test (marine)

Colombo Magnesium Test (marine)

The Colombo Magnesium Test is also suitable for the Mastertronic, so you should select the Giesemann test, as the Colombo is equivalent to the Giesemann test. You will need two test sets to fill the Mastertronic reagent bottles up to 20ml.

The Colombo Marine Magnesium test accurately measures the magnesium content in seawater. It is user-friendly and provides reliable results.

Magnesium plays a crucial role in maintaining a sufficiently high calcium concentration (Ca) and hardness (kH) in the water. If the magnesium concentration is too low, it can have a negative impact on both the calcium concentration and hardness in your aquarium.

The ideal magnesium content ranges between 1300 and 1400, but this can vary depending on the calcium and KH values.
