Red Sea Magnesium Test Lab
* Tests marine magnesium levels with 20 ppm accuracy
* Magnesium helps you keep proper calcium, alkalinity, and pH levels
* Essential test kit for reef aquariums

Marine aquarium titration test for magnesium - accurate to 20 ppm. In addition to biological functions, magnesium helps maintain proper calcium levels to prevent a drop in alkalinity and sudden drops in pH. Includes full instructions, test tube, and easy-read color scale.

Magnesium plays an important role in the marine aquarium, as it is used by most animals along with calcium in construction of skeletons and shells. It also helps prevent the excess precipitation of calcium and bicarbonate, which lowers both the calcium level and causes a drop in alkalinity. A low alkalinity leaves the aquarium vulnerable to sudden drops in pH, which can be fatal to aquarium inhabitants. It is important, therefore, to ensure that magnesium is maintained at the correct level, according to the salinity of the aquarium.

Magnesium should be maintained at about 3 times the level of calcium in ppm.
