UNS Controsand Bora is a fine, light cream-to-white natural aquarium sand (about 0.4–0.9 mm grain) from Ultum Nature Systems. Its pale tone gives dark hardscape and green plants strong contrast, ideal for beach-style layouts, riverbed paths and Iwagumi foregrounds.
Smooth grains are gentle on Corydoras, loaches and dwarf shrimp. Rinse before use.
