Concentrated Magnesium supplement for all marine and reef aquaria
Brightwell Aquatics Magnesium is a highly concentrated ionic magnesium solution that provide magnesium which helps regulate the balance between calcium & carbonates in aquarium water. It is also a component of aragonite, the mineral secreted by reef building organisms such as corals, clams and their allies to form skeletal material.
Magnesium plays a vital role in reef aquaria as it helps maintain the calcium and carbonate concentrations. If magnesium levels fall, calcium & carbonate ions bond together lowering their levels and causing a false impression that more is required. No matter how much calcium is added, the natural level of 412 ppm will not be achieved until the magnesium level is returned back up towards 1290 ppm.
The rate at which magnesium is used up will depend on stocking density of reef building livestock, type of lighting etc. Keeping a level of magnesium between a range of 1290 to 1320 ppm will maintain the desired balance.
