Salifert Trace Hard is a concetrated additive designed for use in the marine aquarium.

It is perfect for the best development of Hard Corals. The blend of trace elements of manganese, iron, cobalt and zinc, will promote good skeletal growth and as such, lush coral formations.

In any marine set up, the trace elements are naturally absorbed from the water, so using a treatment such as Trace Hard will ensure levels are at the optimum level.
