Two Little Fishies Magnesium Pronto is a high-purity blend of anhydrous magnesium chloride and magnesium sulfate, specially formulated to quickly and effectively raise magnesium levels in marine aquariums.
Maintaining proper magnesium levels is essential in reef aquariums, as corals, clams, snails, tube worms, and coralline algae continually absorb magnesium from the water to build their skeletal structures. Magnesium also plays a key role in maintaining proper calcium and alkalinity balance.
