Description

Pisces USA AquaNatural Coarse Aragonite is a natural calcium carbonate substrate designed for marine and reef aquariums. It helps maintain stable pH and alkalinity (8.0–8.4) while releasing essential minerals that support healthy corals, invertebrates, and select freshwater species. Its porous structure promotes beneficial bacterial growth for enhanced biological filtration, and the coarse grade makes it ideal for high-flow aquarium systems.
