Absolue Purple is a highly concentrated natural aragonite solution derived from the sea. It contains the correct proportion of calcium, magnesium and aragonite necessary for the well-being of corals and especially enhances the growth of the highly desired purple and pink coralline algae. The use of Absolue Purple will greatly accelerate the formation of coralline algae in the reef aquarium.

Absolue Purple also replenishes iodine and strontium which are essential elements for coralline algae.
