TestPro Magnesium

This test kit is for marine aquarium keepers who need to monitor magnesium alongside calcium and carbonate hardness. Magnesium helps buffer the water and keeps calcium and bicarbonates from precipitating too readily, so regular checks make it easier to spot drift before it affects the tank.

Why it matters

• Magnesium takes part in building the skeletons of hard corals, so its level directly affects coral growth.
• It supports the buffering capacity of the water and limits excessive precipitation of calcium and carbonates.
• Natural seawater contains 1260–1500 mg/l (ppm) of magnesium, which gives a concrete reference point for your readings.
• One kit provides enough reagent for 55–60 magnesium determinations, so it covers a long period of routine testing.

What it works with

The test is designed for marine aquariums, including reef tanks with hard corals, where magnesium, calcium and carbonate hardness are monitored together. It is suited to routine checks of seawater parameters in these systems, and the readings can be compared with the natural seawater range given above.
