The main characteristics of SPS Sea Salt are high calcium, high magnesium and high trace elements, which are suitable for the absorption and propagation of hard corals. These indicators are higher than the concentration of oceanic seawater.

The Reef Sea Salt index is close to the concentration of marine sea, suitable for all kinds of marine ornamental organisms breeding and growth.

The indicator of Tropic Fish Sea Salt is slightly lower than Reef Sea Salt, because the growth of fish does not need too high calcium and magnesium and other elements.

Aquaculture Sea Salt, the purity of raw materials is lower than the above three kinds of sea salt, so the index can be low, suitable for aquatic fish growing nearshore or deep marine sea.
