ARAGONIT 4.6 Kg – Natural Coral Sand for Active and Bacteria-Rich Substrates
ARAGONIT is a pure, natural coral sand ideal for creating biologically active and stable marine aquarium substrates. Harvested exclusively from pristine beaches near coral reefs, it provides the perfect foundation for the growth of benthic microfauna and beneficial nitrifying bacteria essential for biological filtration.
When used in combination with ZEObak and Zeostart, it quickly transforms into a living and fully active substrate within hours, accelerating tank maturation and improving ecosystem stability. Its natural composition and granule structure promote bacterial colonization and help maintain stable pH and KH levels, making it perfect for reef systems.
